Honeywell® FS24XPlus™ | User Manual
12
Notes:
l
Heater turns ON at -13°F [-25°C] in Normal Operation)
l
Heaters are used during extreme cold to bring the internal electronics up to a
minimum temperature. During this time, which can last up to 30 minutes
when the environment has a temperature of -55°C, the internal
microcontrollers are not running, halo will be off and the current loop will
report less than 1.5 mA.
l
12W = 0.67 A at 18 V or 0.5 A at 24 V worst case.
Inrush Current is 0.75A for a maximum duration of less than 5ms.
Weight:
Aluminum 3 lbs. 11 oz. (1.7 kg)
Stainless Steel 7 lbs. 7 oz. (3.4 kg)
Flame Detection Performance:
See Appendix 2: FS24X Plus™ FM Performance Appendix for
details of specific fuels, detection distances, and false alarm
immunity.
Note that fire is random and chaotic. The Flame detector will
typically respond in less than 10 seconds.
Housing material:
Low Copper (less than 0.25%) marine grade Painted casted
Aluminum of ASTM A356.0 grade.
Polished cast Stainless Steel of ASTM CF8M grade.
Outputs:
Fault, Alarm and Auxiliary SPDT relays Max. 32 Vdc/ac, max. 2 A,
min 10 mA at 12 V resistive load.
4-20 mA source, sink or isolated current output. Uncertainty is 1%
of reading.
FP2 over RS-485 and USB (USB is accessible through Detector
Module electronic device only).
Modbus over RS-485.
HART
The FS24XPlus™ Flame detector has HART® 7 communication;
registered with FieldComm Group. EDD and DTM files are
available.
Local notification indicator:
LEDs HALO Light ring. Shows instrument status.
HALO is visible at 50 ft. in daylight conditions. Suitable for indoor
and night applications.
