5 Maintenance
Most modern control units do not require periodic adjustment or field repair other than replacement of a module or printed circuit board assembly. Defective printed circuit board assemblies or modules can best be serviced at the manufacturer’s plant or at their authorized service facility. Where the control unit uses printed circuit boards, care should be taken to clean off excessive dust. The boards should be maintained clean and dry to ensure proper operation.
5.1Auto Reset feature (One-man test)
This function only works when the panel is in the standby mode. Pressing sets the panel into one-
man test mode. When a zone goes into alarm, the audible circuits are pulsed ½ second for identification of the zone; i.e. zone 1 has one pulse, zone 2 has two pulses, etc. After the zone number is pulsed, the panel automatically resets the zones by cycling power. After 15 minutes of no activity, the panel provides
5 pulses on the NAC and goes back into standby condition. Pressing again (no pulses with this exit) returns the panel to standby condition.
5.2Inspection and Test procedure
5.2.1Testing the control panel
Notify the building occupants, the fire department and/or receiving station personnel before and after testing is performed. Notify the fire department and/or other receiving station personnel if alarm,
supervisory, and/or trouble signals are transmitted. (Transmissions may be inhibited by pressing .)
In addition to the testing procedures described below, the FireLarm 2500 system and all of its associated protective signaling adjuncts should be inspected and tested in accordance with the
1.Notify the proper building personnel so audible and/or visual signals can be viewed as a test by building occupants.
2. Press | . This will cause all audible and visual indicators on the panel and the NAC outputs to | |
come on. Releasing | will restore the panel to the condition it was in prior to operation of this | |

3.Press each . This will result in a trouble condition and operate all indicators as described in section 2.5.5 Initiating Zone Trouble. Repressing will restore all indicators to normal.
4.Momentarily open each of the following circuits. Observe that each of these results in a trouble condition and appropriate indicators operate as described in the section for the particular circuit that is faulted. (See section 2.5.5 Initiating Zone Trouble)
•Each initiating device zone (there is a brief delay when these circuits are in the Style D (Class A) mode.
•Supervisory circuit.
•Notification appliance circuit
5.Momentarily shunt each of the circuits listed in the previous step (except the supervisory circuit) with 4.7K ohm resistor and again observe that a trouble condition is generated for each test. Use 1.5K ohm for the supervisory circuit.
6.Turn off the AC power at the circuit breaker panel. The green
