Installation Instructions
1 Overview
The EN1242 smoke detector is a wireless, battery powered photoelectric
smoke sensor. The sensor includes a built-in sounder for alarm alerts, a
visual status LED, and an Inovonics Wireless EchoStream transmitter. The
sensor works as part of a security/fire alarm system and communicates
with the system control panel. Under normal (non-alarm) conditions, the
LED flashes once every eight seconds while the sensor monitors the
surrounding conditions. When the sensor detects smoke, the LED lights,
the built-in sounder beeps loudly, and an alarm signal is transmitted. The
smoke sensor is powered by the two included three-volt lithium batteries.
When the EN1242 detects an inactive smoke sensor a tamper message
will be transmitted.
Note: The EN1242 smoke detector transmitter is intended for use as a
supplemental residential fire alarm device, and is only UL listed to provide
localized functional annunciation.
