not be permitted to be transmitted as a General Alarm or Zone condition.
Wiring
 All initiating device circuits, and signal line circuits shall be Class “A” with a minimum of 4-feet separation
between supply and return circuit conductors
 All notification appliance circuits shall be Class “B”
 The Initiating Device Circuit from an addressable device used to monitor the status of a suppression system
may be wired Class B, provided the distance from the addressable device is within 10-feet of the suppression
system device.
 Wiring may not be supported by the ceiling grid support wires.
 Suspended wires added to support the fire alarm wiring must be painted red and attached to the above

Devices
 Detectors shall not be installed until after all other construction trades have completed cleanup unless
specifically required. Detectors required to be installed during construction shall be cleaned and sensitivity
tested before commissioning of the system. (NFPA 72, 17.7.1.11)
 A smoke detector is required over all fire alarm control panels, notification power supplies, and monitoring
transmitting equipment. (NFPA 72, 10.4.4)
 Duct detectors shall be supervisory in constantly attended occupancies all other shall initiate an alarm signal.
(NFPA 72, 21.7.4 & 21.7.4.1)
 Duct detectors shall be provided with a listed alarm indicator and remote reset switch which is accessible
from the floor without a ladder, or have the ability to be reset from the fire alarm panel.
(NFPA 72, 23.8.5.4.6.4)
 Tamper switches shall be individually addressed and labeled to match the description that is programmed in
the fire alarm control panel. (Example: Tamper 1)
 Where two or more strobes are visible, they shall be synchronized.
Fire sprinkler monitoring systems
In addition to all other requirements the following are specifically required of fire sprinkler monitoring systems.
 Fire sprinkler monitoring panel or an annunciator panel is required in the fire riser room
 Fire sprinkler monitoring panel shall be labeled “FIRE SPRINKLER MONITORING PANEL” and any annunciator
panel identified.
 Primary power shall be a dedicated circuit that is indicated in red and labeled “Fire sprinkler monitoring
circuit”. Location of dedicated circuit disconnecting means shall be identified in the panel.
 All valves controlling the water supply for automatic sprinkler systems, pumps, tanks, water levels and
temperatures, critical air pressures, and water-flow switches on all sprinkler systems shall be electronically
supervised. Exception: fire department hose connection valves
 Water flow switches must activate an alarm within 90 seconds. (2013 NFPA 72, sec.17.12.2)
 Sprinkler and standpipe system water-flow detectors shall be provided for each floor tap to the sprinkler
system.
 Manual dry standpipe systems shall be supervised with a minimum of 10 psig and a maximum of 40-psig air
pressure with a high/low air supervisory alarm.
 Provide a weatherproof horn strobe as close as practicable to the fire department connection.
Completion and System Documentation
 A Texas Department of Insurance installation certificate shall be provided.
 A record of completion in accordance with NFPA 72 verifying that the system has been installed in
accordance with the approved plans and specifications shall be provided.
 Operating, testing and maintenance instructions and record drawings (“as-builts”) and equipment
specifications shall be provided at an approved location and conform with NFPA 72 section 7.7.2 Document
Accessibility.
Inspection & Testing Requirements
The following tests and inspections are required for new installations or modifications of existing systems.
 Rough Wiring/ above ceiling: All fire alarm wiring shall be inspected for proper installation and penetration of
any firewalls. Fire alarm wiring shall not be tied to ceiling grid wire. Contact Code Enforcement/Permitting
Department for low voltage electrical inspection.
 Initial Acceptance test: Contact Fire Prevention Division at least 48 hours prior to scheduling initial
acceptance test.

A representative from all fire protection systems interconnected with the alarm system must be
present at the time of the acceptance testing unless these components have previously been tested.
(sprinkler, vent hood extinguishing, etc.)
All analog or addressable systems will have all devices pulled and/or activated. The print out must
comply with the devices that were pulled.
Water flow alarms will be tested by opening the inspectors test connection and must activate alarm
system within 90 seconds.
Supervising station must contact Fire Department within 3 minutes of device initiation with proper
occupancy address and device identification.
Verification of class A wiring required by testing device on opened circuit and verification of trouble
signal on open circuit required
Fire Alarm System Modification Requirements
Documentation for fire alarm system modifications shall follow NFPA 72 section 7.5.6.6 Revisions.

 Plan submittal to the Fire Prevention Division is only required for the following modifications:
o Addition or modification of initiation devices (such as smoke, heat, pulls and water flow switches)
o Panel replacement only if relocated. (requires acceptance test)
o Addition of power supply or panel of any type
 Minor fire alarm system modifications (such as adding horn/strobe for fire sprinkler monitoring or expanded
notification coverage) do not require plan submittal. Work not requiring plans submittal: Contractors shall
