Figure 3. Antenna wiring as shipped
‰ Option 2: Hang antenna in wall (longest range).
When you mark the back mounting plate's two
mounting holes, also mark where the antenna
hole is (see Figure 2 for antenna wire hole loca-
tion).
Where the antenna hole was marked, drill a
hole into the wall.
Remove the antenna loop (see Figure 3) from
the panel cabinet clips and feed through the
antenna hole and down into the wall.
‰ Option 3: Optional antenna housing (included in
accessory pack) and attach it to the panel (medium
range).
Push the antenna housing down into the top-
right hole of the panel until it snaps into place
(see Figure 4).
Remove the antenna
loop from the last clip
on the panel cabinet
and insert it into the
antenna housing.
9. Place panel cabinet into back
mounting plate and snap into
place.
Connecting Detection Devices to Panel
Zone Inputs
Zone input is supervised using a 2k-ohm, end-of-line (EOL)
resistor (included with panel) at the last device on the cir-
cuit. It accepts either normally open (N/O) or normally
closed (N/C) detection devices.
The maximum loop resistance for each zone input is 300
ohms, plus the 2k EOL resistor.

Connecting Intrusion Detection Devices

Figure 5 shows the typical wiring for N/C and N/O door/
window intrusion detection.

Connecting the AC Power Transformer

(22-117)
The panel must be powered by a plug-in stepdown trans-
former that supplies 8 VAC, 300 mA.
Connect the power transformer to the panel as shown in
Figure 6.
CAUTION
Do not plug in the power transformer at this time. The panel
must be powered up using the sequence of steps described
in the "Powering Up the Panel" section

Connecting the Backup Battery Pack

The panel will receive its primary power from an AC class
II transformer. In the event of an AC power failure, the
panel will be powered by a battery pack containing four
rechargeable NiCd batteries.
