Control Panel Checkup - Fire-Lite Alarms MS-4012 Instruction Manual

System Test - Slide the system test switch down and ensure that all LEDs except the zone alarm LEDs light.
Release the switch and ensure that all alarm LEDs light. Note: The Supervisory LED may not light during
System Test, depending on whether or not Zone 4 is programmed for supervisory service. To test the
Supervisory LED, remove the jumper across Terminals 9 and 10, creating a supervisory condition. If the LED
lights, it is good.
Conclusion - If the problem still exists, four conditions may prevail:
Problems concerning the AC power supply or the batteries are covered in Section 5.2.
5.2 Component Troubleshooting
Battery Test (Battery Trouble Indication)
The batteries may be tested by conducting the procedure in Section 4.7.
Transformer Test (AC Power LED off)
Ensure that circuit breaker CB1 is not tripped. Measure the AC voltage applied to the transformer primary
winding (pins 5 & 7 on plug P1- see Figure 3L for plug locations). This voltage should fall in the range 102
- 132 VAC. Measure the transformer secondary voltage on plug P1 to determine if it falls within the following
specifications: P1 - Pins 2 & 3: 24 - 32 AC volts

If any LED fails to light or the audible trouble device fails
to sound, the panel must be repaired or replaced.
a) Main board has failed.
b) Power Supply (transformer) has failed.
c) Batteries have failed.
d) Combination of the above three.
If the AC led is on, the transformer can be eliminated as the source of
the problem. If the battery trouble LED is off (but passed the system test),
the batteries are not the source of the problem. If the batteries and
transformer are known to be good, have the panel repaired or replaced.
QUALIFIED SERVICE PERSONNEL ONLY!
The test procedures in Section 5.1 must be conducted prior to conducting the
test in this section in order to accurately troubleshoot the control panel.
If the transformer secondary voltage does not
meet specifications, replace the transformer.
