To install the circuit board onto the back plate (Figure 7),
insert the antennas into the antenna shrouds, then gently
slide the top of the circuit board under the two top latches,
and snap the circuit board in at the bottom latch to secure it
in place.

Wiring
To wire the receiver, do the following:
1.
Remove power (if applied) from the control panel.Use 22-
gauge, or larger, stranded wire to connect the +12, GND,
and DATA terminals on the receiver (Figure 8) to the power,
common, and data terminals on the control panel.

DIP switch settings
The DIP switches (Figure 7) on the circuit board are used to set
the receiver module number. Use Table 2 to set the DIP switches
to the desired module number.
Power up
When you apply power to the control panel, the green (power)
LED on the receiver (Figure 8) blinks for approximately 10
seconds. Table 3 describes the receiver status based on LED
conditions.The lower red LED at the bottom of the receiver
(Figure 8) may emit a dim glow, but is not used as an indicator.

LED indications
Green (power) LED status
Meaning
Power-up blinks
LED blinks represent Product Version Number
(PVN). Long blink on is 1, short blink on is 0. PVN
is in binary, from most significant to least signif-
icant bit.
Off
No packets from sensors being received.
Short blink on
Receiver received a valid packet from an
unknown sensor.
Long blink on
Receiver received a valid packet from an
enrolled sensor.
Red (data) LED status
Meaning
Off
No data communication with the control panel.
Check wiring and power source.
Short blink on
Normal data communication with the control
panel.
