7. Operating Instructions

7.1 Scope

The following instructions are designed to obtain optimal performance from the

detector over its life-cycle.

7.2 Power-Up

1 Apply power and wait up to 40 seconds for the automatic self-test of the

detector.

Note:

Applying power initiates the following sequence:

• The yellow LED blink (2 Hz)

•

BIT is executed.

If successful then:

•

The yellow LED blink (0.5 Hz)

•

Fault Relay contacts close

2 Wiring inspection. If a short-circuit or line discontinuity exists, indications will

appear on the control unit display panel. Review your wiring.

3 The detector goes into its FAULT state when supply voltage drops under

16.5V. The detector status goes back to NORMAL when the supply voltage

is above 17.5V.

4 Detector inspection: Visually inspect the viewing window of the detector. It

should be clean and clear. The yellow LED should blink (0.5Hz) and the

Alarm and Accessory Relays should be off and the Fault Relay should be on.

5 If any of the outputs or indications is different from the description in step 3,

see section 8.6 for troubleshooting.

7.3 Reset

To reset a detector when in Alarm Latch state, turn OFF power supply for 10

sec., or initiate a manual BIT.
