1. Public Address Systems

This document provides best practices, based on the collaboration of members from the Telephony; Voice, Data and Video (TVDV) working group and CG Subject Matter Experts (SME’s). All cabling installed at U.S. Coast Guard (CG) facilities shall follow the most current Telecommunications Industry Association (TIA) requirements and specific CG system requirements in this document.

1.1. Description: Public Address (PA) systems are an electronic sound amplification and distribution system typically using a microphone, amplifier and loudspeakers to allow a person to address or alert a large amount of people. Certain events require personnel to be informed either immediately (in the case of an emergency), continuously (during an event or evolution) or as needed. Events and services that utilize the PA system include but are not limited to:

a. Emergency alerts or alarms

b. Intrusion alarms

c. Mass broadcast or zoned notification

d. Morning Colors, Taps

e. Emergency, all zone override

f. Background music, entertainment, and official ceremonies (portable systems)

g. Locating people and night ringers

1.2. Operation: The PA system is accessible by dialing paging access codes via telephone through the VoIP or PBX system, or by using a microphone station.

PA systems can be installed or portable and can accept inputs via analog, digital or IP signal. Systems can be architecturally configured with many zones and grouped zones to provide coverage indoor and outdoor, in single buildings and/or campus environments comprised of many buildings. Notifications are sent to a variety of speakers types to provide different capabilities. Some examples are:

a. Auto answer speakers

b. Talk back speakers

c. Portable or podium-based speakers

d. Telephone sets

e. Grouped zones

f. Zones

1.3 Installations and Recapitalizations: PA system installations and recapitalizations are coordinated by Mr. John Bibby @ TISCOM EISI. A new installation provides all hardware and wiring for sites that do not currently have PA system capability, or, the expansion of an existing system. A recapitalization replaces an existing system in its entirety that is deemed obsolete or beyond economical repair.

(This document defines the standards to be used for Shore-based Public Address systems within the U.S. Coast Guard)

a. Units may request PA system installation or recapitalization via CG Memo or CGFIXIT (Remedy work order) to the EISI PL via their Servicing ESU.

b. Once a PA system project is initiated, an EISI Project Manager will perform a site survey with assistance from the servicing ESD or the Unit’s IT Support.

The PM will develop site drawings, Statement or Work (SOW) and Independent Government Estimate (IGE).

c. PA system recapitalizations are normally funded by the EISI Product line using AFC-42, as funding becomes available. New PA system installations or expansions are normally funded by the requesting unit.

d. If PA system work is included as part of a larger civil engineering project to renovate or construct new facility, this work will be funded using AC&I or AFC-42 SSMR as applicable.

e. The PBX IDIQ contract is the sole source for all materials and installation services for PA system work at shore facilities. To standardize the installations and support, units are not authorized to use alternate solutions or vendors.

f. Portable PA systems are funded and maintained solely by the Unit. The EISI PL does not provide or support portable PA Systems.

2. Installation Standards:

2.1 Hardware Frames: All hardware shall be terminated on frame room backboards.

If a backboard space in a designated telecom space is not available, a fire-rated backboard shall be installed. The thickness of the board will match the existing frame, or if a new backboard is installed, shall not be less than 5/8” thick and securely mounted to wall joists. All backboards should be painted to match existing backboard colors or a light colored paint for new backboards.

a. On occasion, hardware is mounted in standard 19” telecom equipment racks when space is available. If installed in telecom equipment racks, the installer shall use manufacturer recommended rack mount brackets for amplifiers, pre-mixers and zone control hardware. Plywood may be installed for termination blocks as needed.

b. The zone control hardware (Telephone Interface Module (TIM), Central Processing Unit (CPU) and a Zone Paging Module (ZPM) modules shall be mounted securely to the backboard (or rack).

c. Multiple CPU modules are connected by front panel RCA data jacks as per manufacturer instructions.

(This document defines the standards to be used for Shore-based Public Address systems within the U.S. Coast Guard)

d. TIM, CPU and up to three ZPM may be connected by internal power and voice ribbon cables.

e. Each CPU will be served by its own power supply.

f. Each screw terminal on a TIM, CPU and each ZPM shall be pinned out to a 66M50 termination blocks. All distribution connections should be made on the opposite side of the block ‘split’ configuration for testing / troubleshooting. Pin use will be labeled using black permanent marker, written on the white conductor separator tabs.

g. Each 6 pin modular jack on the TIM (trunk, station, over ride) will have a connector, and pinned out to 66M50 blocks. All pin out connections will be made on the opposite side of the block ‘split’ configuration for testing / troubleshooting. Pin use should be labeled using black permanent marker, written on the white conductor separator tabs.

h. ZPM modules will be labeled with zone numbers (i.e. zones 1-3, zones 13-15, etc).

2.2 Cabling Installation Standards:

a. Single pair shielded speaker wire shall be used for all installation in the CG.

Beldon P/N 2C18FS-CMR-GY-B-BED (non-plenum) or 2C18FS-CMP-NA- RFA-BED (plenum) specifically.

b. All speaker cable runs shall ‘home run’ to the nearest telecommunications closet. Speakers shall not be connected in series, parallel, or daisy-chained.

c. Industry standard telephone terminal blocks such as the 66M50 will be used to terminate cable runs. Terminal blocks shall be labeled with the specific speaker served.

Note: Speaker cable associated with the standardized PA installation at Shore Units is the only installation that braided Cable is authorized for punch down block termination in the CG.

d. Cables shall be tagged with speaker numbers within 1 foot of each end. Cable tags should be visible, ink should be indelible and printing should be at least 12-pitch.

e. Exposed cable in some locations shall be placed inside conduit or low voltage raceway.

f. ‘As-built’ redline drawings shall be completed indicating the basic cable routes.

(This document defines the standards to be used for Shore-based Public Address systems within the U.S. Coast Guard)

2.3 Speaker Installation Standards:

a. Speakers shall be identified and labeled by number. Identification shall follow this order:

Building number-floor-type-XX

Example: 215-01-F-12

Building number 215, 1st floor, flush mount speaker, speaker #12

Speaker Type designation: S = Surface mount speaker ceiling X = Exterior horn speaker B = Box wall speaker F = Flush mount speaker assembly

b. Each flush mount ceiling speakers and box wall speakers will have a built-in volume control. Each horn speaker will have a built-in wattage adjustment.

2.4 Amplifier and Electronic Device Installations:

a. All amplifiers, preamps, mixers, will be visibly labeled in a professional manner with lettering of indelible ink, font no less than 14 pitch and include:

Building name-floor served-zone-amp wattage

Amplifier Example: Hangar-2E-1-100 (2E = 2nd floor East)

Pre-amps will be labeled using this example:

Preamp example: Hangar-2-1-pre

Mixers will be label using this example:

Mixer example: Hangar-2-1-mix

More than one amp serving the same area will have the addition of .x at the end of the designation.

Example: Hangar-2E-1-100.1 Hangar-2E-1-100.2

b. Amplifier locations will be identified on the ‘as-built’ drawings with their designation and location as close to the actual location as possible.

c. The Bogen TPU model amplifiers and Zone Control assembly have built-in pre-amplifiers.

d. The zone control assembly and tone generator may be rack mounted in a

(This document defines the standards to be used for Shore-based Public Address systems within the U.S. Coast Guard)

USCG provided rack.

e. Any control buttons connected to the TG4C alarm generator should be push-button, single pole-single throw. They shall be labeled with their designated use in a professional manner using no less than 14 pitch lettering.

2.5 Equipment Standards:

a. Amplifiers: There are 2 standard amplifiers used in the CG; the Bogen TPU-

60, and the TPU-100.

b. Zone Controls: Several years ago, Bogen introduced a sophisticated zone paging controller know as the Paging Control Module 2000 (PCM). A PCM unit consists of a Telephone Interface Module (PCMTIM), Central Processing Unit (PCMCPU) and a Zone Paging Module (PCMZPM). Each zone module supports three zones.

• The units primary PCM assembly must have:

1 PCMTIM

1 PCMCPU

and at least 1 PCMZPM

• Up to three PCMZPM’s may be stacked, allowing the primary unit to have 9 zones plus all-call (zones 00-09). This assembly requires one PCMPS2 12vDC power supply. Additional assemblies consisting of a CPU and up to three ZPM’s may be added, increasing the possible system zone count to 99. The second set would be zones 10-19, a third set would be zones 20-29, etc. CPU’s are connected with an RCA type plug on each CPU. A switch on the CPU identifies the CPU’s and what zone assembly they are

in. Each CPU assembly requires a power supply.

• The Bogen PCM Zone Control has multiple configurations and can use any combination of modules. Configuration will be based on information gathered during the site survey and documented in the as-built drawings.

(This document defines the standards to be used for Shore-based Public Address systems within the U.S. Coast Guard)

TIM CPU ZPM

c. Tone Generators: Bogen model TG4C Multiple Tone Generator and Bogen VMix are capable of generating four distinct signals: pulsed tone, slow whoop, repeating chime, and steady tone. Each of these four signals may be applied continuously or limited to a double burst (single burst only of the steady tone) for alarm signaling or pre-announcement. Signals are triggered by an external device that provides a contact closure. Both tone level and pitch are adjustable.

(This document defines the standards to be used for Shore-based Public Address systems within the U.S. Coast Guard)

d. Speakers: There are four (4) types of speakers authorized for use in the CG.

Surface mount, 2 type of ceiling mount and a horn type.

Surface Mount:

Ceiling Mount:

Horn type:

(This document defines the standards to be used for Shore-based Public Address systems within the U.S. Coast Guard)

2.6 Additional Hardware:

a. All installations will include a tone generator assembly for sending alarm tones in the event of an emergency. The Bogen VMix assembly will support a Bogen TNGS1 tone generator card. It is recommended that the card be placed in slot 6. In order to decrease the noise potential, a Bogen RIO1S (relay in/out) card should be installed in slot 7. Because of internal audio signal BUS connections, most locations will use the RJ11 jack on the RIO1S card, connecting directly to the RJ11 Override jack on the PCMTIM module. This connection using a multi-conductor cable will provide audio and relay control to the TIM module. Operation of any alarm will override all other inputs to the PCM assembly and play the alarm over all zones. In some locations, the alarm assembly does not serve the entire campus. Later paragraphs discuss other alarm signal solutions.

b. Control switches for the VMix alarm generator will be installed in the Operations area. In most cases, existing switches will be reused. If new switches are required, these switches should be push-button, single pole-single throw. They shall be labeled with their designated use in a professional manner using no less than 14 pitch lettering. Tones used should be: SAR (slow-whoop), Fire (siren) and if used; Crash (burst/steady) and General (mechanical bell).

c. On occasion, a large campus with multiple commands may limit the alarms to the Search and Rescue response units/areas. In this case, the alarm audio signal may be connected to the BGM (back ground music) input on one or more ZPM modules. BGM jumpers should be adjusted to allow the signal to pass to zones that should hear the alarm signal. In some cases, noise will

(This document defines the standards to be used for Shore-based Public Address systems within the U.S. Coast Guard) cause the amplifiers to constantly operate. Most often a Bogen WMT1A (line matching transformer) placed in the circuit will help eliminate the noise.

d. Some units play music for colors. Most often colors music is played on the outside zone/s only. The standard zone configuration uses the last zones (or on very large locations, multiple zones using the last available zone numbers) for colors. In this case, the music audio signal may be connected to the BGM (back ground music) input on the last zone of the PCM assembly ZPM module. BGM jumpers should be adjusted to allow the signal to pass to the zone/s which will hear the music. In some cases, noise will cause the amplifiers to constantly operate. Most often a Bogen WMT1A (line matching transformer) placed in the circuit will help eliminate the noise. At no time is it suggested that the audio source stay connected to the Bogen PCM assembly.

Most music sources provide battery to their output ports (RCA, screw terminal, phono jack), causing constant noise. The music source is always provided by the unit.

e. Additional hardware may be required based on unit specific needs. These connections and parts could include:

• Connecting a location specific music source (i.e. medical clinics).

• Connecting a location specific audio input source (i.e. event podiums with auxiliary output).

• Bogen PCM talkback modules.

• Ambient noise sensors.

• Digital feedback eliminators.

• Assorted Input modules for the VMix assembly.

2.7 Inter / Intra-Building Connections:

a. All locations that are supported by Coast Guard owned and maintained copper and fiber cable plant between buildings (or secure spaces) can receive public address hardware. Connection is only made by using the existing outside cable plant. The scope of the project PA system installation project does not include new outside plant.

b. The Coast Guard takes responsibility for identifying cable paths for the installation vendor to connect low voltage audio signals for the Public Address System. It is preferred that low voltage PA audio signals be placed on the upper pair count of any outside copper cable used for inter-building service. In no case shall 70V audio signal be transported on inter-building cables. The PA system installation vendor will make the connection to the cable pairs assigned by USCG.

(This document defines the standards to be used for Shore-based Public Address systems within the U.S. Coast Guard)

c. In cases where the outside plant will not support the installation of low voltage audio signals, the site may employ VoIP. Bogen offers 2, 4, and 8 port VoIP units. If required, the installation team will install and program the Bogen VoIP assemblies. The Coast Guard support ESU/D will program a VLan for use. Both the vendor and Coast Guard must work together to assure connection and to test service. VoIP is the preferred solution for access to secure areas where copper cable plant penetration of the secure space is not authorized.

Due to each LAN having its own C&A package it is the decision of the ESU (ISSO) whether to allow use of a VLan as a last resort for extending PA service.

(This document defines the standards to be used for Shore-based Public Address systems within the U.S. Coast Guard)

3 Basic Troubleshooting

Each installation includes a one year warranty for parts and labor from the installation vendor. All failures during this warranty period should be reported to Mr. Tom Juratovac, TISCOM (EISI-PL) for resolution @ 510-409-4835.

After the warranty expires, standard support procedures are used for all electronics hardware support. In all cases, each supporting ESU/D/DD is left with an initial supply of spare parts to substitute for failed parts. Confirmed failed parts may be shipped for repair or replaced (if the part value is low, the part may not be repaired and will be replaced with local disposal of failed part).

Each servicing shop received at least one Bogen TPU100 amplifier as a shelf spare. A TPU100 may substitute for a failed TPU60 amplifier. Although most amplifiers installed as part of this project are loaded at about 60% capacity, TPU60 should never be used to substitute for a failed TPU100 amplifier.

3.1 Amplifiers:

a. Is the power LED on?

- If not, check your AC outlet

- If not and AC power is good, depress the overload protection breaker.

b. Is the peak level LED on?

- Is the amplifier hot? The amplifier should never be hot to the touch.

Unload the amplifier by opening the 70V output circuit, most often accomplished by removing bridging clips from the 66M50 block used for the amplifiers distribution. Shorts in the 70V output circuit are the most common cause of overheated amplifiers. Leave the output circuit open for several hours to see if the amplifier cools down

(This document defines the standards to be used for Shore-based Public Address systems within the U.S. Coast Guard) and/or overload protection breaker stays on.

c. On occasion, an amplifier could overload from an input source. If the amplifier remains overheated even after the output signal load is removed, the amplifier input circuit/s should be opened.
