When pressing the Reset button, do not touch the
Frequency Band pins. Touching the Frequency Band
pins while pressing the Reset button can inadvertently
set the detector to the wrong frequency band.
4.0 Mask the Zones
If masking is required, use Figure 6 to mask the appropriate zones.
Use opaque masking material, such as electrical tape.

To enable the look-down zones, peel the mask from the look-down
lens. Refer to Figure 2 on page 1 for the location of the look-down
lens.
5.0 Install the Battery
Remove the tab from the battery’s (+) terminal.
Refer to Figure 2, page 1.
The detector must stabilize for at least 3 min after
power-up, at which time the detector is not
operational. During this period, the LED blinks once
per second.
When the 3-min stabilization period ends, the
detector requires a 2-sec quiet period. After the 2-sec
quiet period, the detector enters walk-test mode and
remains in this mode until it detects no motion for
120 sec.
6.0 Register the Transmitter
To ensure that the detector is supervised by the system receiver,
you must register its transmitter with the system receiver. Each
detector has a unique factory-programmed identification number.
Refer to the receiver, network coordinator or control panel
installation instructions for details on registering a transmitter.
1. If necessary, open the detector housing.
2. When prompted to reset the detector, press the Reset button.
Refer to Figure 1 on page 1.
If using the optional housing screws for added security, use a
2.78 mm (7/64 in.) bit to drill out the housing holes on the top
and bottom of the detector housing.
3. Close the detector housing.
7.0 Test the Detector
To ensure correct operation, test the detector after it
registers with the system receiver. To test the
detector, activate each of the conditions and ensure
that an appropriate response occurs.
1. During the 3-min stabilization period, press and release the
housing tamper switch to cause a tamper condition.
Refer to Figure 2, page 1, for the location of the housing
tamper switch.
2. When the stabilization period is complete, replace the housing
cover, and walk in front of the detector to create an alarm.
