When using this feature, operation of initiating devices shall result in limited system outputs, so that the notification appliances operate for only a few seconds and the event is indicated on the system printer, but no other outputs occur. A yellow indicator light must be provided to indicate when a zone is under test conditions.

2.1.10.12 History Logging

In addition to the required printer output, the control panel shall have the ability to store a minimum of 400 events in a log. These events shall be stored in a battery-protected memory and shall remain in the memory until the memory is downloaded or cleared manually. Resetting of the control panel shall not clear the memory.

2.1.10.13 RS-232-C Output

Each local control panel shall be capable of operating remote service type cathode ray tubes (CRTs), printers, and/or modems. The output shall be paralleled ASCII from an EIA RS-232-C connection with a baud rate of 1200 or 2400 to allow use of any commonly available CRT, printer, or modem.

2.1.11 Amplifiers, Preamplifiers, Tone Generators

Any amplifiers, preamplifiers, tone generators, digitalized voice generators, and other hardware necessary for a complete, operational, textual audible circuit conforming to MFPE shall be housed in a fire alarm control unit, terminal cabinet, or in the fire alarm control panel. The system shall automatically operate and control all building fire alarm speakers except those installed in the stairs and within elevator cabs. The speakers in the stairs and elevator cabs shall operate only when the microphone is used to deliver live messages. Each amplifier shall have two channels; one to broadcast a message and the other for paging.

Amplifiers shall utilize computer grade solid state components and shall be provided with output protection devices sufficient to protect the amplifier against any transient up to 10 times the highest rated voltage in the system.

2.1.11.2 Inputs

Each system shall be equipped with separate inputs from the tone generator, digitalized voice driver and panel mounted microphone. Microphone inputs shall be of the low impedance, balanced line type. Both microphone and tone generator input shall be operational on any amplifier.

2.1.11.3 Tone Generator

The tone generator shall be of the modular, plug-in type with securely attached labels to identify the component as a tone generator and to identify the specific tone it produces. The tone generator shall produce a slow whoop tone, which shall slowly ascend from low (500 hertz) to high (1200 hertz), and shall be constantly repeated until interrupted by either the digitalized voice message, the microphone input, or the alarm silence mode as specified. Each slow whoop cycle shall last approximately 4 seconds. The tone generator shall be single channel with an automatic backup generator per channel such that failure of the primary tone generator causes the backup generator to automatically take over the functions of the failed unit and also causes transfer of the common trouble relay.

2.1.11.4 Protection Circuits

Each amplifier shall be constantly supervised for any condition which could render the amplifier inoperable at its maximum output. Failure of any component shall cause automatic transfer to a designated backup amplifier, illumination of a visual "amplifier trouble" indicator on the control panel, appropriate logging of the condition on the system printer, and other actions for trouble conditions as specified.

2.1.12 Manual Stations

Provide metal or plastic, semi-flush mounted, double action, addressable manual stations, which are not subject to operation by jarring or vibration. Stations shall be equipped with screw terminals for each conductor. Stations which require the replacement of any portion of the device after activation are not permitted. Stations shall be finished in fire-engine red with molded raised lettering operating instructions of contrasting color. The use of a key or wrench shall be required to reset the station.

2.1.13 Notification Appliances

Fabrication marks and holes shall be ground and finished to provide a smooth and neat appearance for each plate. Each plate shall be primed and painted.

2.1.13.2 Visual Alarm Signals

Provide strobe light visual alarm signals which operate on a supervised 24 volt DC circuit. The strobe lens shall comply with ACTIVFIRE and the MFPE.

The light pattern shall be disbursed so that it is visible above and below the strobe and from a 90 degree angle on both sides of the strobe. The strobe flash output shall be a minimum of 15 candela based on the MFPE and ACTIVEFIRE requirements. The strobe shall have a xenon flash tube.

Visible appliances may be part of an audio-visual assembly. Provide synchronized operation of all strobes in the facility. The visual alarm devices must comply with AS1603.11.

2.1.13.3 Connections

Provide screw terminals for each notification appliance. Terminals shall be designed to accept the size conductors used in this project without modification.

2.1.14 OPTICAL FLAME DETECTION

Optical flame detection will be the X3301 Multispectrum IR Flame Detector manufactured by Det-Tronics. Optical flame detection system will use triple infrared (IR)flame detectors listed/approved for the expected fuel hazards in the building and meet EN54-10 standard. The detectors will be immune to radar and radio frequency emissions. Provide shielding for the detectors and their circuits from radio frequency interference. All circuiting from the FDCIE or FSCP to the detectors will be shielded, and shielding will be grounded at one end. Optical flame detector alarm signals to the FDCIE or FSCP will be latching.

Detectors must be mounted in accordance with their listing at approximately 8 ft. (2.4 m) above the finished floor of the room. The specifics for each design must take into account facility construction, piping and equipment configuration and positioning, fixed and mobile equipment within the area, and all other relevant factors. Do not mount optical detectors in inaccessible locations. The detectors will be angled and blinds will be provided such that the cone-of-vision does not extend more than 5 ft.

(1.5m) outside the area being protected. The horizontal and vertical axis of the detector determined during commissioning will be permanently marked on each detector. The optical flame detectors will be installed with 5 ft.

(1.5 m) of flexible conduit to allow for any minor adjustments during testing or changes in mission. Provide a sufficient number of optical flame detectors such that a fire at any position within the area being protected will be within the range and cone-of vision of at least one detector.
