OPERATION

5.1 Normal
When the system is healthy only the green supply LED will be illuminated.
5.2 Alarm Condition
An Alarm condition will occur on abnormal Infra-red detection by the Sensor Head.
Normally this status will Latch On, however in special configurations the condition can be
set to momentary operation; auto resetting after a selected delay.
During the ALARM :-
•
One or more Red DETECTOR indicators will be illuminated.
•
The Red ALARM indicator will be illuminated.
•
An ALARM output is signalled by means of a relay contact.
5.3 Trip condition
A Trip condition will occur on abnormal Infra-red detection by the Sensor Head.
Normally this status will be coincident with the ALARM condition and will Latch On.
In special configurations the condition can be set such as to require more detector triggers
than for ALARM. Similarly, the condition can be set to momentary operation; auto resetting
after a pre-selected delay.
During the TRIP :-
•
One or more Red DETECTOR indicators will be illuminated.
•
The Red TRIP indicator will be illuminated.
•
A TRIP output is signalled by means of a relay contact.
5.4 Reset
Latched Alarm and Trip conditions may be normalized by :-
•
Operation of the Controller's integral Reset push-button.
•
Operation of the remote reset push-button / signal (if implemented)
5.5 Fault Warning
The equipment continuously monitors for various fault conditions and is equipped with
indicators to identify the failure.
•
Yellow AIR FAULT indicator illuminated - Sensor Head "purge air" failed.
•
Yellow SEN FAULT indicator illuminated - Sensor Head disconnected.
•
Yellow AUX FAULT indicator illuminated - Auxiliary equipment fault input signal.
•
Green 24 V ON indicator extinguished - Electrical supply failed.
On any of the above conditions a FAULT output is signalled by means of a relay contact.
The indications and output will automatically normalize on rectification of the fault.
5.6 Lamp Test
Operation of the Controller's integral Lamp Test push-button illuminates all indicators.
Output relay signals are not initiated on this test.
5.7 Head Test
Operation of the Controller's integral Head Test push-button signals the Sensor Head and
simulates a detection condition on all circuits. The system will respond as if a true Alarm /
Trip condition has occurred, including operation of Alarm & Trip relay contact outputs.
