6.2 Using the Reset Switch
The purpose of the Reset switch is to allow you to clear an alarm when you turn off a circuit
breaker. When you press the Reset switch, any alarms currently existing are cleared but any new
alarm will be reported.
Use the following procedure:
1. If for some reason you need to turn off power to a particular circuit, switch the circuit
breaker to an off position and then immediately press the Reset Switch.
2. When ready, turn the circuit back on.
7 MAINTENANCE
Maintenance includes performing a routine inspection and replacing a circuit breaker.
7.1 Performing a Routine Inspection
1. Inspect the panel for damage to the circuit breakers and for damaged or broken wires at the
power and external alarm connections.
2. If excessive dirt is found during the inspection, brush or wipe dust and dirt from the panel
with a soft bristle brush or soft cloth.
3. If any circuit breaker is broken or damaged, replace the circuit breaker.
7.2 Replacing a Circuit Breaker
Any existing circuit breaker may be field-replaced with an identical circuit breaker or with a
breaker that has the same rating. Use the following procedure to replace an existing circuit
breaker with a new breaker:
1. Turn-off or disconnect the power from the power bus (either A or B) that supplies current
to the circuit breaker to be replaced.
2. Press the Reset switch to suppress alarms for the “off” circuits.
Note: Switching the circuit breaker back on returns the circuit to the normal alarm
reporting mode. If any other circuit has an active alarm that was cleared by the Reset
switch, that alarm will continue to be cleared until the circuit breaker for that circuit is
turned back on.
Caution: Take care to avoid damaging the circuit breakers or wiring.
Danger: During normal operation, the terminal connections on the circuit breakers are
electrically energized. Failure to disconnect the power from the power bus that supplies current
to the circuit breaker being replaced may cause severe personal injury to the installer and/or
equipment damage.
