Intelligent Base Mounted IR
Installation & Maintenance Guide
General
The Intelligent Base Mounted Triple Infra-red (IR
designed for use where open flaming fires may be expected. It is sensitive to low-frequency,
flickering infra-red radiation emitted by flames during combustion. False alarms due to such
factors as flickering sunlight are avoided by a combination of filters and signal processing
techniques. This product is not compatable with the 45681-321 isolator base.
Response to flames
In quiescent condition, i.e., in the absence of a flame, the detector returns an analogue
value of 25. When a flame is visible, the detector signals an alarm by increasing the ana-
logue value returned to 55, usually within 1.5 seconds. The analogue value may continue to
rise until it reaches a pre-set maximum of 64.
In the alarm state the IR
Flame Detector latches for 20 seconds, with the analogue value
³
decreasing to 25 once the flame is no longer detected.
Electrical considerations
The IR
Flame Detector is loop powered and needs no external supply. It is connected to a
³
control panel using either the XP95
or Discovery
®
may be connected to the flame detector.
Sensor window contamination
It is important to keep the sensor window clean and checks should be carried out at
regular intervals–determined locally according to the type and degree of contamination
encountered–to ensure optimal performance of the flame detector. Although flames can
be detected when the window is contaminated, there may be a reduction of sensitivity as
shown in the table overleaf.
It is recommended that the IR³ Flame Detector be disabled when the window is being
cleaned.
