COMMISSIONING
4.1 Cable
Checks
The installation wiring should be checked for correct connection, continuity and insulation.
For relay mode implementation the relay coil link connections at terminals 6/7 & 8/9 should
be checked. Refer to figure 8 section 2.7.1.
For line powered (trigger circuit) mode the Alarm resistor at terminals 2/7, and EOL (end of
line) resistor at terminals 2/9 should be checked for both correct value and fitment. Refer to
figure 9 section 2.7.2.
Terminals 25/26 should be linked if appropriate.
4.2 Unit Set Up
The program SIL switch must be set for the required operation.
The setting below is for double channel coincident detection with a 1.3s scan. The unit
latches on coincident alarm until manually reset.
The detection sensitivity is set to level B.
4.3 Power Up Procedure
Note 1:
The unit has three signaled / output states which are monitored by
remote equipment. These are referenced as Normal - Fire - Fault in the following.
For relay mode :
Normal = Fire relay de-energized & Fault relay energized.
For low power mode : Normal = EOL resistor connected across trigger circuit.
Fault = EOL resistor disconnected from trigger circuit.
Fire = Alarm resistor connected across trigger circuit.
Note 2:
The tests of 4.3.2 & 4.3.3 can only be conducted with the enclosure lid /
fascia open. This may not be permissible in hazardous areas in which case go
straight to 4.3.4.
4.3.1
Apply power to the detector. (Connect supply or trigger circuit)
Check supply = 20 to 30 Vdc for relay mode or 13 to 30 Vdc for relay mode.
4.3.2
Operate detector Test PB - Check : Detector Alarm LEDs A & B illuminate.
Operate detector Reset PB - Check : Detector Alarm LEDs A & B extinguish.
4.3.3
A general check of detector field of view may be conducted at this stage whilst the
module LEDs, Reset PB and SIL switch is still accessible. Refer to section 4.4.
For “Single Knock” mode Pole 3 may be set ON for non-latching alarms.
For “Double Knock” mode Pole 4 may be set ON for auto-reset.
The SIL switch must be returned to the setting of 4.2 before proceeding to 4.3.4.
4.3.4
Fit detector lid and connect compressed air hose.
4.3.5
Check at the Detector that purge air is blowing from the optical aperture.
4.3.6
Momentarily remove the electrical supply and check that the unit signals Fault for
the duration of the supply interruption.
4.3.7
If an air pressure switch is employed momentarily interrupt the air supply and
check that a the unit signals fault.
