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 shall be kept as
required by the authority having jurisdiction.
• Required tools:
-Slotted screwdriver, insulated
-Digital multimeter
-1.1 k
Ω , 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 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 be powered when primary
power is lost, the batteries should be periodically
inspected, tested, and replaced (at a minimum) every four
years.
Preventive maintenance schedule
Refer to NFPA 72, Chapter 7 Inspection, Testing, and
Maintenance, Canadian Electrical Code Part I, ULCS524, or
ULCS536 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, directly short one leg of the circuit to
chassis ground
. The Ground Fault and Trouble LEDs must
light.
For NAC and IDC open circuit tests, remove the EOL resistor
from the last device on the circuit. The Trouble LED must
light.
For NAC short circuit testing, place a short across each NAC
output individually. The individual NAC LED must light as
well as the common LED.
For AUX power short circuit testing, place a short across the
+24 V and -24 V at the panel. The common trouble LED must
light.
For communications testing, place a short across C+ and C-.
The annunciator trouble LED must light.
