FSL100 Series Flame Detectors 
Technical Handbook 
  FSL100 General Specifications   
Selectable LEDs and relays latching/non latching, factory 
setting: latching 
- a fire control panel by means of end of line (EOL) and alarm 
resistor (current increase) 
- a device that can take relay outputs 
- a PLC with a 0–20 mA input 
 
 
End Of Line And Alarm Resistor 
To match the fire control panel, free terminals dedicated for 
the resistors are available 
Note: the alarm and EOL resistors must be rated 2 W minimum 
each and the total power dissipation of both alarm and EOL resistors 
should not exceed 2 W 
 continuous green: normal operation 
 continuous yellow: fault (blinking yellow: repeated self-test after a 
self-test fault) 
continuous red: alarm 
 
De-energized during normal operation, no alarm, SPDT, 30 VDC – 
2 A, 60 W max. 
Energized during normal operation, no fault, SPDT, 30 VDC – 2 A,
