About this file
This document is Chapter 6 of an electrical design criteria guide for Job Corps facility construction projects, specifically addressing fire alarm and security systems.
Fire alarm systems must comply with NFPA-72 requirements and be equipped with Class A zoned systems determined through code analysis. All fire alarm wiring shall be installed in conduit with no exposed or plenum cable permitted. Required components include hardwired heat or smoke detectors for individual spaces, audio/visual notification devices compliant with ABA Accessibility Standards and NFPA 72, local annunciation panels at building entrances (lockable and accessible to fire departments), and flow/tamper switches on sprinkler systems. Multiple buildings may utilize a central fire alarm control/annunciator panel if underground connections are feasible and cost-effective. Independent testing by a fire protection engineer is mandatory, with written certification required confirming compliance with design and NFPA-72 requirements. Complete fire alarm riser diagrams must show all devices and wiring methods without "typical" notations. Building-specific criteria apply to administration buildings (central annunciator panel normally located in security office), cafeterias (connections to fire suppression systems for kitchen hoods with gas solenoid valve and electrical disconnects), housing units (smoke detectors in sleeping rooms with presignal alarms to RA offices), and recreation facilities (device guards to prevent damage).
Security systems shall be designed based on risk analysis, with wiring installed in conduit and kept separate from fire alarm systems to preserve life-safety reliability. Two security types are addressed: intrusion detection and unauthorized egress detection. Housing units require egress detection systems on all exterior entry/exit doors with concealed, tamper-proof contact devices reporting to the RA office. Administration buildings may require intrusion systems with master control panels in the security office. The document specifies that commissioning of fire alarm systems is required per the Statement of Work, with effort levels varying based on facility systems.

Chapter 6: Electrical Design Criteria
6.6 Fire Alarm System
6.6.1 General
All fire alarm system installations shall meet the latest NFPA-72 requirements. In general, there will be no direct connection to the local fire department unless the center will not have security staff on site around the clock. When there is 24-hour security, all alarms will be monitored and investigated by the security staff. Upon determination of a fire, notification of the local fire department will be made by the security staff. Should In an area where local code requires direct connection of the main fire alarm control panel to the fire department, the A/E shall bring this to the attention of the ESC PM for resolution.
If required by code, all buildings will have a fire alarm system equipped with a “Class A” zoned fire alarm system. The A/E shall define and describe the fire detection systems protection goals for each building in accordance with the classification of the building. The occupancy-specific requirements of NFPA 101 and subsequent requirements of NFPA 72 shall be used to design the required fire/smoke detection, initiating and notification system. The proposed fire alarm system and component selections shall correlate with the required written code analysis. These items shall be carefully coordinated and discussed with the ESC beginning with detailed code analysis and design narrative. All fire alarm system wiring shall be installed in a conduit system.
When multiple buildings are constructed, a central fire alarm control/annunciator panel will be specified if underground connections are feasible and the installation would result in a lower installed cost. The decision for a central panel or connections to an existing centralized system shall be carefully considered in terms of cost and maintenance.
The fire alarm system must be tested by an independent testing agency in accordance with NFPA-72, Section 7-1.2.2, and witnessed by a registered fire protection engineer. The tests must include those outlined in the latest edition of NFPA-72 and any additional tests deemed necessary to establish the adequacy, quality, safety, and suitability of operation of the system. The required sequence of operations is to be tested. A written certification by the fire protection engineer, indicating that the system is performing in accordance with the design and the requirements of NFPA-72 and that it is installed in accordance with manufacturer requirements and the intended design, will be required as well as all required documentation as outlined in NFPA72. Provide for adequate training and O&M materials by carefully noting these requirements within the construction documents and coordinate in relevant specification sections.
Carbon Monoxide monitors shall be provided as required.
6.6.2 Fire Alarm Design
All fire alarm wiring shall be installed in a conduit system; no exposed cable or plenum cable will be permitted. Each building fire alarm system shall be equipped with the following fire alarm system devices as determined through code analysis:
A hardwired heat or smoke detector for each individual space requiring monitoring.
Audio/Visual notification devices shall be located as required to comply with the ABA
Accessibility Standards provided by GSA+ requirements, and NFPA 72. (Provide candela values on plans for assuring code compliance; devices allowing adjustment shall require field testing with settings documented in test reports and as-built drawings.)
Provide a local annunciation panel identifying the status of the building’s fire alarm system devices for each building zone. The panel shall be located at the building entrance that is accessible to the fire department. Each building system shall function independently. Panels at entrances shall be lockable.
For assembly spaces, smoke detectors shall be installed in storage, janitor closets, electrical/mechanical rooms, and all tenantless spaces areas not occupied, as required by code. Where nuisance alarms will occur frequently (such as kitchen areas), heat detectors will be provided in lieu of smoke detectors as allowed by code.
Flow and tamper switches on all sprinkler systems connected to the fire alarm system for monitoring and alarm initiation.
6.6.3 Riser Diagrams
Provide a complete fire alarm riser diagram. This riser is to show all devices and wiring methods.
Wiring details for the system shall be included on the riser diagram. “Typical” notations are not acceptable. The A/E shall show all heat detectors, smoke detectors, duct smoke detectors, pull stations, audio/visual devices, annunciators, fire alarm panels, battery boxes, flow and tamper switches, and all other devices and connections which are to be installed on both plans and fire alarm risers. Special requirements shall be indicated. Portions of the fire alarm system that are to be provided by other disciplines (e.g., duct smoke detectors) will also be indicated, and cross referenced.
6.6.4 Details
All controls that will be a part of the fire alarm system are to be indicated. Locations, devices, and wiring methods are to be indicated. The controls will include fire shut down of air handling equipment, and other similar systems in accordance with all applicable codes.
6.6.5 Building-Type, Specific Criteria
6.6.5.1 Administration
The central annunciator panel will normally be located in this building for new centers.
However, if there is a designed Welcome/Security building on the campus, then the panels should terminate at that building. The security office, which is normally manned 24 hours a day, 7 days a week, is used to monitor this panel and investigate any alarm signals prior to contacting the fire department for assistance.
6.6.5.2 Cafeteria
Provide all necessary connections to the fire suppression system for each kitchen hood used for cooking. The system shall be connected to the fire alarm system, gas supply solenoid valve, and electrical appliances under the hood so that the gas and electrical sources will be disconnected in the event of a fire under the hood. This requirement extends to hoods provided for culinary arts.
6.6.5.3 Education
Pull stations will be provided with cover plates that will discourage nuisance tripping of these devices.
When a culinary arts vocation is provided, it shall meet the same requirements as the cafeteria.
6.6.5.4 Housing
The local control/annunciator panel shall be located in the RA’s office with a remote annunciator at the entrance.
Provide detailed drawings indicating the dimensioned locations of all fire alarm devices.
Coordinate these locations with furniture and architectural features.
Provide smoke detectors in all sleeping rooms with appropriate wire guards. Activation of these devices shall cause a presignal alarm in the RA’s office.
Pull stations will be provided with suitable covers to minimize nuisance alarms by the occupants.
6.6.5.5 Medical/Dental (Wellness Center)
There are no Job Corps-specific criteria for this building type.
6.6.5.6 Recreation
Provide suitable guards that will prevent damage to detection, notification and initiating devices.
Pull stations will be provided with suitable covers to minimize nuisance alarms.
6.6.5.7 Warehouse and Maintenance
There are no Job Corps specific criteria for this building type.
6.7 Security System
6.7.1 General
DOL attempts to provide a non-institutional atmosphere for the student population, and emphasizes student/staff interaction over electronic surveillance. In keeping with this philosophy, elaborate electronic security systems are generally discouraged. The security system will be designed as dictated by the risk analysis.
6.7.2 Security System Design Standards
In general, there are two types of security: one to detect intrusion, and one to detect unauthorized egress from a building. Depending upon the system that is chosen, the process used for notification will vary. When egress detection is provided, such as in dormitories, the notification of unauthorized egress shall be provided to the Resident Advisors office. In areas where intrusion detection systems are to be provided, the alarm reporting method will vary. This notification could vary from a local audible alarm to notification to a central location at the security desk. Any security system wiring shall be installed in a conduit system. A security system shall not be an integral part of a fire alarm system. The fire alarm system is considered as being required for life safety and as such its reliability in general will not be jeopardized through integration with non-life-safety systems.
6.7.3 Riser Diagrams
All devices, which are a part of the security system, shall be shown and identified on the riser and on the plans. The A/E shall differentiate between security systems designed for intrusion protection, and those that are designed to detect egress from the buildings.
6.7.4 Details
All devices that are to be a part of the security system are to be indicated on the drawings.
Wiring requirements will be shown in detail. Location of main, local, and annunciator panels shall be shown as necessary for proper construction.
6.7.5 Building-Type, Specific Criteria
6.7.5.1 Administration
The site of the master security system control panel (if applicable) will normally be located in this building. The security office, normally manned 24 hours a day, 7 days a week, is used to monitor this panel and investigate any alarm signals generated. An intrusion system may be required for this type of building. Due to the various types of facilities that are constructed, the need for, and type of system, including requirements for local or central alarm annunciation, shall be coordinated with the ESC PM.
6.7.5.2 Cafeteria
There is no Job Corps specific requirement for this building type.
6.7.5.3 Education
There is no Job Corps specific requirement for this building type.
6.7.5.4 Housing
An egress detection system will be designed for all housing units. All exterior entry/exit doors shall have contact devices. All contacts shall be concealed, for example, in the door jambs and of a tamper-proof design and construction. Unauthorized egress alarms will report directly to the Resident Advisors office. Controls in the Resident Advisor’s office shall be provided to activate/deactivate the detection system. There is no need for central notification of this type of alarm. Local door alarms which can be activated and deactivated manually by a key are often a viable cost saving alternative.
6.7.5.5 Medical/Dental (Wellness Center)
There is no Job Corps specific requirement for this building type.
6.7.5.6 Recreation
There is no Job Corps specific requirement for this building type.
6.7.5.7 Warehouse and Maintenance
There is no Job Corps specific requirement for this building type.
