The JA-85ST Wireless combined smoke and heat detector
The JA-85ST Wireless combined smoke and heat detector
2 / 2
MLW55605
Caution: When the detector is installed in caravan trailers, use only
the “smoke only“ or “both smoke and heat” settings.
4. Proceed according to the control panel installation manual.
Basic procedure:
a.
Switch on the enrollment mode in the control panel.
b. When you insert all batteries into the detector, an enrollment code
is sent to the system – its sending is confirmed with a short flash
of the LED indicator (3).
c.
The control panel confirms the enrollment with a flashing of the
“A“ LED on the system keypad at the corresponding position.
Note:
The detector can also be enrolled into the system by entering its
production code (5) in the O-Link program. (Enter the last 8 digits
under the bar code).
5.
Insert the detector into the plastic base.
The detector can be
inserted into the base in one position only. It is marked with
arrows (4) on
both
plastic parts. Close the detector cover by
turning it clockwise (2).
Note:
Detector cover closing is blocked unless all 3 batteries
are inserted!
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 in the
Devices
window in the
O-Link
program and with the configuration terminals.
The
Reaction
option in the
Devices
window allows you to set the
type of reaction of the system to the activation of the enrolled
detector. The configuration terminals on the detector PCB
determine other reactions:
SIR
enables deactivating the built-in siren.
MEM
alarm memory signalling – if enabled, the detector LED
remains active for an additional 24 hours Signalling can also be
terminated by pressing the detector body against the base.
SMOKE and TEMP
the combination of these terminals defines
whether the detector will react to smoke and heat.
INST
if a reaction different than
NATURAL
is set in the
O-Link
program, the control panel will react as set in the program.
Fire alarm
A fire alarm
is signalled acoustically and optically according to
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 and quick flashing the LED indicator (3).
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
then, the siren is reactivated.
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 5 s after silencing the
siren. When the detector chirps, you have to release the pressure
within 1 s. 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, alarm indication continues even
when the smoke clears or when the temperature decreases. The
slow-flashing indication lasts 24 hours unless it is terminated by
pressing the detector body.
Tamper alarm:
When the detector cover is opened, the detector
sends a tamper signal.
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
the LED indicator switches on. The LED flashing signals switchover
to test mode. The LED 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.
The result of a test is sent to the control panel. If the detector is
OK then the LCD keypad shows the text “Test OK”. When there is a
problem or fault then the keypad shows the text “Fault”.
The complete functioning of the detector can be tested with a test
spray (e.g.. SD- TESTER) ) or hot air (e.g a hair dryer).
If the control panel is not in the SERVICE/MAINTENANCE mode,
a fire alarm is triggered.
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 briefly 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 briefly.
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 and if the batteries are
running low, the detector signals that they need replacing by short
flashes repeated every 30 s. The information is also sent to the
control panel. Replace the batteries as soon as possible.
Exchange procedure:
-
If the detector is already enrolled to the system it’s
necessary to enter service / maintenance mode
-
open the detector
-
remove the old batteries
-
press and hold the test button (8) until the LED (3) goes ON
-
when the LED goes OFF , it shows the capacitors inside the
detector have been discharged
-
insert some new batteries
Always replace all three batteries with the same type and
manufacturer.
Use only high-quality 1.5 V AA alkaline batteries.
Do not throw used batteries into ordinary household waste.
Deposit them at authorized collection points.
