9. 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.
Table 3. 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.
