5. Install anchors where studs are not present.

6. Partially insert a screw into the top mounting hole location then hang the back mounting 

plate on the screw.

7. Recheck for level, insert the lower screw, and tighten both mounting screws.

8. Install the antenna. There are three antenna options to choose from:

• Standard Range- Leave the antenna as is.

• Extended Range - Attach the optional antenna housing (included in the accessory 

pack) to the remote station.

a.Push the antenna housing down into the top right hole of the remote station until it 

snaps into place (see Figure 2).

b.Remove the antenna loop from the last clip on the remote station cabinet and insert 

it into the antenna housing.

• Longest Range - Hang the antenna in the wall.

a.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 location).

b.Where the antenna hole was marked, drill a hole into the wall.

c.Remove the antenna loop (see Figure 2) from the remote station cabinet clips and 

feed through the antenna hole and down into the wall.

9. Place the remote station cabinet into the back mounting plate and snap into place.

The remote station has one hardwire input. The input is 
supervised using a 2.2 k Ohm, end-of-line (EOL) resis-
tor (included with the remote station) at the last device 
on the circuit. It accepts normally closed (N/C) detec-
tion devices. Figure 3 shows the typical wiring for a N/
C door/window intrusion detection.

The maximum loop resistance for each zone input is 
300 ohms, plus the 2.2 k Ohm EOL resistor.
