Curtain A (without the reflecting mir-

Curtain B (with the reflecting mirror)
covers these areas:
If you want to use the curtain lens and
select Curtain A, follow these steps to
remove the reflecting mirror.
1. Use a Phillips screwdriver to
remove the screw from the printed
circuit board (PCB), then lift out
the PCB.
2. Use pliers to squeeze together the
two tabs on the back of the PCB,
then gently lift the mirror from the
PCB.
3. To prevent reflections from the
sensor’s internal components
from affecting the sensor, put the
supplied rubber ring over the sen-
sor.
WIRING THE SENSOR
To wire the sensor to the alarm sys-
tem’s protection loop and to connect it
to 9- to 16-volt DC power, you need
24-gauge or larger six-wire cable (Ra-
dioShack Cat. No. 278-874).
