Installation Instructions - 05362F
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: For UL installations, refer to the EN4216R Installation and Operation
Manual or the EN7285 Installation Instructions.

2.3 Select the Frequency Band
EchoStream products are able to use a range of radio frequencies, and
must be configured for your geographic area. To configure the transmitter:
1. Place a selection jumper on the appropriate frequency band selection
pins.
• Place the jumper on the left two pins, marked AU, to set the frequency
range to 915-928 MHz for Australia.
• Place the jumper on the right two pins, marked NZ, to set the
frequency range to 921-928 MHz for New Zealand.
• Leave the jumper off the pins to set the frequency range to 902-928
MHz for North America.
2. Press the Reset button to complete configuration.
Caution: When pressing the Reset button, make sure you don't also touch
the frequency band selection pins. Touching the frequency band selection
pins while pressing the Reset button can inadvertently set the device to the
wrong frequency band.
