Chapter 5: Diagnostics, maintenance, and testing
Vigilant VS1 and VS2 Technical Reference Manual 183
Control panel testing
Before starting, 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
-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.
For annunciator communications testing, place a short across channel 1 (+ and −)
and verify that the system Trouble LED turns on. Repeat for channel 2.
