SENSOR MODULE REPLACEMENT
Replace the sensor module after 5 years operation (or by the date on the ‘REPLACE SENSOR BY’
label on the side of the unit).
After 5 years operation, the amber light will flash once every 40 seconds (without a beep) to indicate the
sensor should be replaced.
(1) Remove the alarm from the mounting plate as described previously.
(2) Pull out the sensor module from the rear (see figure 6).
(3) Replace with a new sensor module (Model No. Ei261MEN - Contact Ei Electronics, for your nearest
module supplier).
(4) Carefully align the module including the connector pins and push firmly home.
(5) Remove the ‘REPLACE SENSOR BY’ label on the side of the alarm.
(6) Slide the alarm back on to the mounting plate.
(7) Wait 4 minutes for the new sensor to stabilise and then press the Test/Hush button - the horn should
sound.
END OF LIFE
Note:
When the second sensor has completed its 5 years of operation the amber light will flash every 40
seconds. The sensor module can only be replaced once.
The entire unit must then be replaced after 10
years
. The date for replacing the entire unit is given on the ‘REPLACE UNIT BY’ label on the alarm.
