To enable the look-down zones, peel the mask from the look-down 
lens. Refer to

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.

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.

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.
