JA-11A RB BUS external siren
JA-11A RB BUS external siren 1 / 1 MLQ54101
The JA-11A RB is a component of the JA-10 system. It is used for
system alarm indication outside a building and as a pre-sensing tamper
detector. It can also be used for supplementary acoustic signalling.
The siren is equipped with a backup battery which powers the siren
during tamper alarm reporting when the connection to the digital bus
is severed. The JA-11A RB is completed by assembling two parts,
the JA-11A-BASE-RB base with the PCB and the JA-1XA-C-WH cover.
The siren occupies one position in the system.
Installation
The siren should
be installed on a vertical
wall, with the flasher
facing down-wards.
Avoid installing the siren
near the gutters and on
other places where there
is a danger of ice
accumulation.

cover for easy
installation
1. Open the external siren cover by releasing the screw (9).
2. Push the bus cable (5) through the hole (4) in the bottom part and
secure it using the plastic tabs.
3. Attach the siren to a suitable place using 2 screws through the holes
(1) and (8). The spirit level can be used for easy installation (7).
When connecting the siren to the system
bus, always switch the power off.

4. Connect the bus cable to the terminals (11).
5. Connect the backup battery to the connector (17).
6. Proceed according to the control panel installation manual.
Basic procedure:
a. When the siren is switched on, the yellow LED (16)
indicates that the siren has not been enrolled into the
system.
b. Go to the N-Link software, select the required position
in the Devices tab and launch the enrollment mode by
clicking on the Enroll option.
c. Press the enrollment button (12) – the siren is thus
enrolled and the yellow LED indicator goes off.
7. Put back the siren cover and attach it using the screw (9).
8. The siren can be tested by N-Link software by clicking the Test
button in the internal settings option. After clicking the button the
siren sounds for three minutes and after that flashes for one
minute.
Internal settings of the siren
The siren properties can be set in the Devices window of the
N-Link program. When at the siren position, use the Internal
settings option to open a dialog window where you can set:
(default settings are marked *):
Setting tab:
Acoustic indication of alarms from sections: to set for which
sections the siren should indicate an alarm, as well as setting chirps.
The default setting is indication for all sections.
Reaction: defines whether the siren should indicate EW* (external
warning) or IW (internal warning); Alarm indication can also be disabled
completely (other functions remain enabled).
Siren sound: intermittent*, continuous.
Maximum siren time: No, 1, 2, 3*, 4, 5 minutes. Option ‘No’ – the
siren doesn’t indicate alarm acoustically (optical indication remains)
During section control: YES / NO* if enabled, the siren chirps once
upon setting and twice upon unsetting and three times upon unsetting
after an alarm. The signalling only works for the preset sections.
Optical indication
Flashes every 60 seconds: YES / NO* optional indication of siren
functioning.
After alarm expiration: During alarms, until memory erased,
30 minutes after an alarm - the optical indication can be extended
until the alarm indication is terminated (by new system setting/
unsetting) or the extended time can be set to 30 minutes after the alarm
expiration.
Signalling PG tab:
The siren can indicate PG output activity with its chirps.
The siren can indicate the activity of selected PG outputs with its
beeps.
Slow beeping - 1 per second (for the whole period when the PG
is active)
Quick beeping - 2 per second (for the whole period when the PG
is active)
1xOn/2xOff - 1 chirp when the PG is activated, 2 chirps when the PG
is deactivated
20 seconds of beeping – a long 20 s beep when the PG is activated
Sound priorities
The siren sound has the highest priority, the control chirps have a
lower priority and the PG output activity indication has the lowest priority
(PG1 has a higher priority than PG2 etc). The chirp with a higher priority
always terminates the chirp with a lower priority.
Loss of communication with the control
panel
If the power supply wire is severed, the siren keeps sounding and
flashing for 3 minutes (this function does not work in service mode). If the
system power supply is disconnected due to a discharged control panel
battery (long lasting power failure) then the siren does not sound and
flash.
Backup battery replacement
The system reports a low battery automatically. The control panel
must be in service mode before you start changing the battery
otherwise a tamper alarm will be triggered. Use a BAT-4V8 battery
only.
