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 approximately 60 seconds for the automatic self-test of

the detector.

Note: Applying power initiates the following sequence:( POWER LED blinks

BIT is executed, if successful then: POWER LED turns ON continuously

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 inspects the viewing window of the detector. It

should be clean and clear. The POWER LED should be ON and the ALARM

LED should be OFF. The ALARM and ACCESSORY relays should be OFF

and the FAULT relay should be ON. The 4-20mA Output should be 5mA.

5 If any of the outputs or indications are different from the description in step 4,

see paragraph 8.6.1 for troubleshooting.

The Flame Detector is now ready for Functional Testing.

7.3 Reset

To RESET a detector when in its ALARM state, disconnect power (terminal No. 1

or terminal No. 2), or initiate a manual BIT.

7.4 Functional testing

Following is a testing procedure for proper functioning of the detector. The

detector can be tested using the Manual Built-in-Test or the Spectrex IR3 Fire
