EN1266 360° Ceiling Mount Motion Detector
Installation and Operation Manual
1 Overview
The EN1266 360° ceiling mount motion detector is a four-element passive
infrared intrusion detector for use in electronic security systems in ceiling
mount applications. The EN1266 reduces false alarms to a minimal level
due to its elimination of background noises and nuisance stimuli, employs
automatic pulse count to make it adaptable to various environments, and
uses sophisticated signal processing to make it virtually free of false
alarms. The lens provides wide coverage patterns, even at low mounting
heights, and is especially immune to sunlight, as well as halogen and
fluorescent lights.

2 Installation and Startup
2.1 Installation Notes
• These products are designed to be installed and maintained by
professional security technicians.
• Products are tested for indoor use.
• All products should be manually tested weekly.
2.2 Install the Batteries
The EN1266 can accommodate two batteries for extra battery life, but only
one is required for operation.
Note:
When installing batteries, it is recommended that batteries are
replaced in new pairs from the same manufacturer.
To install batteries:
1.
Remove the housing cover from the base.

2.
Install the batteries included with the unit.

2.3 Select Pulse Count
The pulse count options provides control for difficult operating
environments. Automatic pulse count is recommended for reliable
operation in environments subject to temperature fluctuation that can cause
false alarms. The single pulse count mode is more sensitive to minor
temperature variations, and should be used in sites where variant heat
sources will not cause alarms. Automatic pulse count is the factory default
because it allows more reliable operation in environments subject to
temperature fluctuation. To select pulse count:
1.
Press the tamper button five times within three seconds.

2.
Wait for the green LED to blink five times, then:
• Press the tamper button one time within three seconds to select single
pulse count.
• Press the tamper button two times within three seconds to select
automatic pulse count.
3.
Confirm your selection.
• The green LED will blink once to indicate single pulse count has been
selected; twice to confirm automatic pulse count has been selected.
2.4 Select Fixed/Variable Sleep Time
The sleep time jumper setting provides control for normal or high-traffic
operating environments. When set to fixed, if the EN1266 senses motion, it
will transmit an alarm, then enter sleep mode for 180 seconds; if motion is
sensed when the sleep time has expired, the EN1266 will transmit another
alarm. Fixed sleep time is recommended for normal operating
environments. When set to variable, if the EN1266 senses motion, it will
transmit an alarm, then enter sleep mode for 180 seconds; if motion is
sensed before the sleep time has expired, the EN1266 will restart the 180
second interval. Variable sleep time is recommended for high-traffic
operating environments, and is the default setting as shipped from the
factory. To select sleep time:
1.
Press the tamper button four times within three seconds.
2.
Wait for the green LED to blink four times, then:
• Press the tamper button one time within three seconds to select
variable sleep time.
