Installation & Maintenance Guide
General
The XP95 Triple Infra-red (IR) Flame Detectors, part no 55000-020 and 55000-021 are
designed for use where open fl aming fi res may be expected. They are sensitive to low-
frequency, fl ickering infra-red radiation emitted by fl ames during combustion. False alarms
due to such factors as fl ickering sunlight are avoided by a combination of fi lters and signal
processing techniques.
Response to Flames
In quiescent condition, ie, in the absence of a fl ame, the detector returns an analogue
value of 25. When a fl ame 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 XP95 Flame Detector latches for 20 seconds, with the analogue value
decreasing to 25 once the fl ame is no longer detected.
Electrical Considerations
The XP95 IR Flame Detector is loop powered and needs no external supply. It is connected
to a control panel using either the XP95 or Discovery protocol. A remote LED alarm indicator
may be connected to the fl ame 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 fl ame detector. Although fl ames 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 fl ame detector is disabled when the window is being cleaned.
