 Wireless Smoke 

Detector

Installation Instructions

1 Overview

The EE1243 EchoStream wireless smoke detector is a wireless, battery 
powered photoelectric smoke sensor. The sensor includes a built-in 
sounder for alarm alerts, a visual status LED, a back tamper, and an 
Inovonics 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 EE1243 detects an inactive smoke 
sensor a tamper message will be transmitted.
