Ei Electronics Ei650i Operating Instructions

40
6. Interpreting signals
(Note: This does not reduce the protection against fire, as an alarm that goes off
constantly due to a fault is useless anyway and must be replaced. The steps described
offer some additional benefits: The user is reminded every 10 minutes, by the two short
beeps, that the alarm must be replaced.) If you press the test button again, you can
silence the alarm for another eight hours.
6.2.3 Damage to the smoke chamber
If the sensors in the smoke chamber are damaged, the alarm gives two short beeps
every 32 seconds and the red LED flashes at the same time. The alarm must be replaced
if this happens.
i series only: If you are not able to replace the device straight away, you can press the
test button to silence the beep and turn off the yellow LED for 12 hours. The red LED
will continue to flash every 8 seconds. This step can be repeated until the battery goes
completely flat, but the alarm should be replaced as quickly as possible.
