5. Operation
LED jumper is used for LED indication without interfering with the detector. Jumper
in ON position (pin 1 & 2) light on. Jumper in OFF position (pin 2 & 3) light off.
Factory standard: LED on.
The P.COUNT jumper controls the pulse count for alarm activation. With the jumper
in the 1P position, the sensor provides maximum sensitivity (one pulse, pins 1 & 2)
With the jumper in the 2P position, the sensor provides intermediary sensitiveness
(two pulses, pins 2 & 3), and in this position, the sensor provides proper detection
for environments with high incidence of EMI and RFI interferences. Factory stan-
dard: 2P.
Note:
if the P.Count jumper is open, the sensor sensitivity will be 2P.
The RELAY jumper controls the relay contact status. With jumper in the NC position,
the contact is normally closed. With jumper in the NO position, the contact is
normally open. Factory standard: NC
