4.1.3 Keeping Maintenance Records

It is recommended that maintenance operations performed on a detector are recorded in a Log-book. The
record should include the following:



Installation date, and contractor



Serial and tag no



Entries for every maintenance operation performed, including the description of the operation,
date and personnel ID

If a unit is sent to Sierra Monitor or a distributor for service, a copy of the maintenance records should
accompany it.

4.2

Troubleshooting

This section is intended to be a guide to correct problems which may happen during normal operation.

Problem

Cause

Corrective Action

LEDs Off; Fault Relay at
N.O. 0-20mA at 0mA

No power at the unit



Check that the correct power is sent to the
detector



Check power polarity



Check wiring in the detector



Send the detector for repairs

Yellow LED flashes at 4 Hz
Fault Relay at N.O.
0-20mA at 0mA

Fault Detector



Low Voltage



Faulty Detector



Check the voltage at the detector; verify at
least 24V at the detector terminal



Send the detector for repairs

Yellow LED flashes at 4 Hz
Fault Relay at N.O.
0-20mA at 2mA

BIT Fault - Faulty
Detector



Clean detector window



Re-power the detector



Replace the detector

Red LED constantly on

If no fire exists, then,
Detector alarm latched

Perform

Reset

to the detector

Alarm Relay at On 0-20mA
at 20mA

Alarm condition



Check cause for alarm



If no alarm, re-power the detector



Send the detector back for repair
