LED Status Indicators
The Model FS24X Detector uses three (3) separate, bright LED's to indicate the Detector's status.
•
The Green LED blinks (flashes) once every ten (10) seconds to indicate a Normal, safe operational
condition (i.e. no Faults and no Alarms). The Green LED is OFF when no external 24 VDC input power is
applied to the Detector.
•
The Red LED turns ON when a fire is Alarmed.
•
The Yellow LED blinks (flashes) when the window lens is dirty. For all other Fault conditions, the Yellow
LED will turn ON.

Normal Operation
In Normal operation, the bright Green LED blinks (flashes) every 10 seconds. See Figure 3-4 for the location
of the Green LED. Normal Operation is defined as the Detector with 24 VDC applied and no Alarm or Fault
conditions are present. If one of the 4-20 mA options are selected (Table 3-1), the current, sink or source, will
be 4.0 mA (±0.6 mA). Only the current source mode has been certified to the EN54-10 standard.
3.5
Alarm Condition
When an Alarm condition occurs, the Red LED will turn ON, (factory setting with the Auxiliary relay set to "0"
seconds). See Figure 3-5 for the location of the Red LED.
