When the height of the installation is less than 6 meters. The distance between the lower surface of
the detector and the ceiling shall not exceed 0.3 m.
The smoke alarm should not be installed within 3m (9.8ft) in front of the air supply ducts.
The detector should be installed more than 0.6 meters away from the wall or the wall-beam.
Detector protection area:
When the space height is 6 ~ 12 meters, the protected area is 60 square meters
When the space height is less than 6 meters, the protected area is 40 square meters
Testing: Push the button on the cover and hold it down. This will sound the detector if the electronic
circuitry, horn and battery are working properly. The detector will emit an audible
‘
Didi tick
’
every 2
seconds and the red indicator on the detector will remain on. If no alarm sounds, the unit has defective
batteries or other failure. Erratic or low sound coming from your alarm may indicate a defective alarm.
Release the button the detector will return to normal operation.
VI. Operation and instructions
Indicator status :
Normal condition: the indicator (green light) flashes every 60 seconds.
Battery low power mode: the indicator (yellow light) flashes every 30 seconds.
Circuit failures condition: the indicator (yellow light) flashes every 2 seconds.
Alarm status: the indicator (red light) remains on.
Buzzer status:
Battery low power mode: emit an audible
‘
Di
’
every 30 seconds.
Circuit failures condition: emit an audible
‘
Di
’
every 2 seconds.
Alarm status: emit an audible
‘
Didi tick
’
every 2 seconds.
Alarm status:
When the concentration of the smoke reaches the set point, the alarm will emit an audible
‘
Didi tick
’
every 2 seconds and the red LED on the detector will remain on during the audible signal.
The alarm can revert to the normal condition when the concentration of the smoke goes lower than the set
point.
Hush function:
The hush function is very useful in a kitchen area or other areas prone to nuisance alarms. If a nuisance
alarm is set off, press the test button and holding it down for a minimum of 3 seconds. This will
temporarily desensitize the alarm circuit, the detector will silence immediately during this time. This
indicates that the detector is in a temporarily desensitized mode. The detector will reset in these following
situations:
A. Higher concentration of smoke;
B. The detector will automatically reset after approximately 1 minutes;
(The hush feature can be used repeatedly until the air has been completely cleared.)

IIX. Maintenance
Test the detector once a week to make sure it works. Never use an open flame or combustible materials to
test the smoke alarm since this may damage the smoke alarm or ignite flammable materials nearby and
cause a fire.
Under normal circumstances, the battery life can reach about five years, but harsh environment such as
high temperature and humidity will shorten the battery life.
