Preventive maintenance
Before commencing testing, notify all areas where the alarm sounds and off-
premises locations that receive alarm and trouble transmissions that testing is in
progress.
Records of all testing and maintenance must be kept as required by the authority
having jurisdiction.
Required tools:
• Slotted screwdriver, insulated
• Digital
multimeter
• 1.1 kΩ, 1 W resistor
• 12 in (30.5 cm) jumper lead with alligator clips
• Panel door key
• Sound-level
meter
A complete check of installed field wiring and devices should be made at regular
intervals in accordance with NFPA 72, Canadian Electrical Code Part I, ULC
S524, and ULC S536 requirements. This includes testing all alarm and
supervisory initiating devices and circuits and any off-premises connections.
Panel operation should be verified in the alarm, supervisory, and trouble modes.
To ensure that the panel can operate correctly when primary power is lost, the
batteries should be inspected and tested periodically. Batteries should be
replaced (at a minimum) every four years.
Preventive maintenance schedule
Refer to NFPA 72, Canadian Electrical Code Part I, ULC S524, or ULC S536 for
more information on required inspection and testing methods and frequency of
fire alarm systems and devices. For detector sensitivity and functionality testing,
refer to the detector manufacturer’s installation instructions.
Canadian tests for grounds, opens, and shorts
ULC requires that you test ground fault, open circuit, and short circuit indications.
For ground fault tests, short one leg of the circuit to chassis ground and verify
that the system Ground Fault LED and Trouble LEDs turn on.
For NAC and IDC open circuit tests, remove the end-of-line resistor from the last
device on the circuit and verify that the system Trouble LED and the circuit’s
trouble (TBL) LED turn on.
