LED Status Indicators
The Model FS20X 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.
3.4 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.
