Operation
WARNING
When the unit is powered up it performs a self-test during which the green LED light
blinks for a period of one and one half to two minutes. Afterwards, the green LED light
will turn on continuously to indicate the unit is in normal operation (ARMED). If the self-
test fails or the green LED light does not turn on continuously do not use. Failure to do
so may adversely affect product performance and
result in sickness or death
.

Power Up
When power is first applied to the detector, it will go through a warm-up period of two and one-half minutes, during
which alarms are inhibited. The green LED light will turn on and off during the delay period. The green light will turn
on continuously (ARMED) afterwards to indicate the unit is in normal operation.
