4.
connect the ALARM and TMP (5) terminals
– first study the
control panel installation manual before connecting the wires to
the detector terminal board
5.
connect power supply to
12 V terminals (6)
6.
Insert the detector into the plastic base.
The detector can be
inserted in the plastic base in one position only. It is marked
with arrows (4) on both plastic parts. Close the detector cover
by turning it clockwise (2). Bear in mind that the connecting
wires must not restrain the functioning of the testing buttons.
Note:
Detector insertion into the base is blocked unless all 3
batteries are inserted!
(only if EN 14604 compliance is required).
When batteryless detector operation is required (EN 54-x), the
blocking mechanisms preventing insertion of the detector without
inserted batteries should be removed.
The mounting base must not be replaced by bases meant for
detectors without the test button consisting of pressing the body
of the detector.
Detector setting
The detector properties can be set with the configuration
terminals.
SMOKE and TEMP
combination of these terminals defines
whether the detector will react to smoke and heat.
When the detector is installed in caravan trailers, use only the
“smoke only“ or “both smoke and heat” settings.
MEM
alarm memory signalling – if enabled,
the
detector LED
remains active for additional 24 hours. The signalling can also be
terminated by pressing the detector body against the base.
SIR
allows deactivating the built-in siren (in stand-alone mode the
siren always works).
BAT
blocks the low battery detection during operation in EN 54-x
mode
Caution: if the detector is used without batteries then it stops
working completely when the +12 V power is disconnected
NO
determines the function of the ALARM output terminal
(switching/break), the TMP output is always NC (break)
Fire alarm
Fire alarm
is signalled both acoustically and optically (depending
on the settings).
When the conditions for fire alarm triggering are met (smoke is
detected in the room, the alarm temperature is reached, or both
conditions are met), the detector signals the danger by sounding
the siren, quick flashing of the LED indicator (3) and activation of
the ALARM output terminal.
Silencing the siren during an alarm:
The siren can be silenced
by pressing the detector body against the base. The siren is
inactive for 10 minutes. If the detector still detects smoke or heat
after this time, the siren is activated again.
When the need arises (e.g. in the case of a detector failure), it is
possible to postpone siren reactivation by up to 12 hours. This can
be done by pressing the detector again for 5s after silencing the
siren. When the detector chirps, you have to release the pressure
within 1s. The switchover to the postponed siren mode is confirmed
with 5 chirps. The detector LED flashes all the time during the
postponement.
Alarm memory:
If it is enabled, LED indication with slow
flashing continues even when the smoke clears or when the
temperature decreases. The indication lasts 24 hours unless it is
terminated by pressing the detector body.
Tamper alarm:
When the detector cover is opened, the TMP
output terminal is activated.
Detector testing and maintenance
The detector should be tested at least once per month.
To
test the detector press the detector against the base and wait until
a LED indicator switches on. The LED flashing signals switchover
to the testing mode. The LED is flashes for the whole duration of
the test. When the test is complete, the LED switches off. The detector
then signals the result. If the detector beeps once, the test has been
done successfully. If a failure is discovered, the LED flashes and
beeps three times. If the battery is low, there is no acoustic
signalling but just one flash when the test is completed.
When the testing is completed the ALARM terminal is activated
for a short time.
The complete functioning of the detector can be tested with a
testing spray (e.g. SD-TESTER). The heat sensor can be tested
with heated air (e.g. with a hair dryer).
Warning: never test the detector with fire.
Fault indication
The detector checks its functioning. If it discovers a fault, it chirps
and flashes the LED three times and then flashes shortly three
times every 30 s.
A detector test can be carried out when a fault is signalled. To test
the detector, press its whole body against the base. During the test the
detector checks whether there is still a fault. The red LED flashes
during the testing. When the test is completed, the LED stops flashing
and then signals the result. A persistent fault is signalled by 3 flashes
and 3 beeps. If the fault has been fixed, the detector chirps shortly.
If you have not managed to fix the fault, the detector must be sent to
a service centre.
Battery replacement
The detector checks the battery status if used and if the batteries
are running low, the detector signals that they need replacing by
short flashes every 30 s. Replace the batteries as soon as possible.
Always replace all three batteries of the same type and
manufacturer.
Note
: For the best possible operation we strongly recommend using
only batteries supplied by Jablotron’s authorized distribution (avoid usage
of so called no-name batteries).
Do not throw used batteries into ordinary household waste.
Deposit them at authorized collection points.
