LED Status Indicators
As with all FSX Detectors, the Model FS17X Detector uses three (3) separate, bright LED’s (rather than one
tri-colored LED that can be difficult to recognize the different colors outdoors or in a brightly lit area) to indicate
the Detector’s status.
The
Blue
LED blinks (flashes) once every ten (10) seconds to indicate a Normal, safe operational
condition (i.e. no Faults and no Alarms). The Blue LED is OFF when no external 24 Vdc input power is
applied to the Detector.
The
Red
LED turns ON when the FS17X goes into ALARM. The Red LED flashes when the FS17X-R
version goes into ALERT.
The
Yellow
LED blinks (flashes) when the window lens is dirty. For all other Fault conditions, the
Yellow LED will turn ON solidly (see Section 3.5).
3.3
Normal Operation
In
Normal
Operation
, the bright
Blue LED
blinks (flashes) every 10 seconds. See Figure 3-1 for the location
of the
Blue LED
. Normal Operation is defined as the Detector with 24 Vdc applied and no
ALARM
or Fault
conditions are present.

Blue LED Location
The number of Blue LED flashes immediately following the
power-up sequence identifies the type of FS17X:
Two (2)
Flashes for the
FS17X-S
(Semiconductor Detector)

(General Purpose Detector)
Six (6)

ALARM
When an
ALARM
occurs, the
Red LED
will turn
ON
, (factory setting with the
Auxiliary
relay set to “0”
seconds). See Figure 3-2 for the location of the
Red LED
.
The Detector has the following
