F-Guard IR3-H2 User Manual

76-M-6010-02-02

Enable dirty window warning 0-20mA 

If enabled, this feature assists predictive maintenance by indicating an alert when the BIT signal has 

reduced by 75% of the value needed to trigger a BIT fault failure.  When activated, the milliampere 

output will drop to 3mA and the LED will remain steady green, it should be noted that a fire signal 

will override the dirty window warning.  A process variable of optical contamination (BIT signal level) 
is 

accessible via HART and / or MODBUS.  The value of the field ranges from 0 (clean) to 100% 

(BIT fault).

 

Auxiliary Relay 

The Aux relay can be set to operate in parallel to alarm relay, at pre-alarm level or on “dirty 

window warning”. 

Window Heater 

The detector is equipped with a heater to prevent condensation and icing on the window. If 

enabled, the heater is operated automatically depending on temperature.  

Modbus Address 

The detector can communicate with the 

Gastech

 communicator software using a Modbus RTU 

compatible protocol on RS-485. This protocol allows for a network of detectors to be connected, 

each with a unique Modbus address. The address of the detector can be set to any value in the 

range 1–247. 

 

Manual BIT – Alarm Output Test (Full Loop test) 

When enabled, the alarm outputs (Relay and mA) are activated when a 

Manual

 BIT is initiated. 

See section 4.2 for details. 

 

WARNING

 

Make sure to disable all fire extinguishing actions or alarms connected to the detector when the 

manual BIT is initiated and the “Manual BIT – Alarm Output Test” is enabled as the Manual BIT will 

set the 0-20mA terminal to 20mA and close the alarm relay and auxiliary relay if configured.
