Press the tamper button two times within three seconds to select fixed
sleep time.
3. Confirm your selection.
The green LED will blink once to indicate variable sleep time has been
selected; twice to confirm fixed sleep time has been selected.
2.5 Register the EN1266
The EN1266 must be registered. Refer to receiver, network coordinator or
control panel installation instructions to register the EN1266.
1. When prompted to reset the transmitter, remove and replace the
batteries.
Caution: The EN1266 should be tested after registration to ensure
operation. To test the EN1266, activate each of the conditions and ensure
an appropriate response.
2.6 Mount the EN1266
2. Use the included four mounting screws to mount the EN1266 mounting
base to the ceiling.
Note: The screw in the middle of the mounting base activates the tamper
function if the EN1266 is removed from the ceiling.
Figure 4 Mount the EN1266
The EN1266 can be mounted to a maximum height of approximately
12 feet (3.6 meters). As mounting height increases, distance between
detection zones also increases toward the perimeter, and the effects
of factors such as floor surface temperature and intruder direction and
speed are intensified. This can contribute to reducing speed of
detection. Every installation should include a walk test of detection
zones, including intrusion paths crossing the edges of the zones.

3. When the housing base has been attached to the ceiling, attach the
housing cover.
3 Test the EN1266
3.1 Walk Test
When in walk test mode the test LED will light red every time the EN1266
senses motion. The unit will not transmit alarm signals during this test
period. Once initiated, the walk test will last for ten minutes and then the
EN1266 will automatically return to normal operation. To initiate a walk test:
1. Press the tamper button three times within three seconds.
Note: The test LED only lights red during the walk test.
4 Operation
The EN1266 contains a tamper switch on the board to alert the user if the
housing cover is removed. The EN1266 also contains tamper contacts in
the mounting bracket to alert the user if the unit is removed from the wall.
