Chapter 5: Diagnostics, maintenance, and testing
Vigilant VS1 and VS2 Technical Reference Manual

Control panel testing
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 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.
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 open circuit tests, remove the end-of-line resistor from the last
device on the circuit and verify that the system Trouble LED turns on.
For NAC short circuit testing, place a short across the NAC output
terminals and verify that the system Trouble LED turns on.
For AUX power short circuit testing, place a short across the AUX
power output’s plus (+) and minus (
−
) terminals and verify that the
system Trouble LED turns on.
