Manual disabling of the detector

It is possible to disable the detector for a 15 min.
period:
• Prior to activities likely to produce dust (sweeping of
a dusty room, of a chimney...) and cause unwanted
alarm activation,
• To stop alarm in the event of detection of non-
dangerous smoke.
In order to disable the detector, press the test key
until the 1st beep sounds or until the detector stops its
built-in audible alarm. The indicator signalling the state
of the detector fl ickers every 2 sec.
After the 15 min. disable period has passed or after
a manual test, the detector is set back automatically
into normal operation with the detector state indicator
fl ickering every 10 s.

Indication of faults

Power supply fault:

Detector at the source of the fault indication
TG 500A/TG 500B
the unit fl ickers once
every 5 sec.
the unit emits 2 fast beeps every 60 sec
If the sound indication of the power supply failure occurs at an inappropriate time, it is
possible to postpone its occurrence for an 8-hour delay over a maximum 7-day period by
pressing the test key until the 1st beep is emitted.
This is the time period available for replacing the battery.

TG 501A
-
For the 15 min. disable period,
the detector will not detect
any smoke, nor emit any
audible alarm.
In the case of an installation
in network and of a non-
dangerous smoke detection, it
is obligatory to inhibit the
detector at the origin of
detection (led red twinkling) to
stop the ringing.
After the power supply fault
has occurred, the detector will
operate normally for a 30-day
period. However is advisable
to replace the battery as soon
as possible.
