jablotron JA-15A Manual

JA-15A Wireless internal siren to an AC socket
The JA-15A is a component of the JA-10 system. It is used for
alarm indication inside a building. It can also be used for other
acoustic indications (PG outputs, entry/exit delays). Pressing the
siren button can silence the alarm (= confirmation of a person's
presence in the building) or trigger a panic alarm (optional function).
The siren is equipped with a backup battery for cases when AC
dropouts can happen. It has also got a built-in detector of siren
tampering by disconnection from its electrical socket.

Installation and enrolling the siren to the
control panel
It is necessary to perform the enrollment procedure in service mode
and the system has to be equipped with an JA-111R radio module.
1. Plug the siren into the required electrical socket where there is
still a good RF range to the control panel.
2. The control button (1) lights permanently with a yellow colour
and it means the siren is ready to be enrolled. If the control
button (1) doesn´t light permanently, then follow the Warning
below.
3. Go to the N-Link software, select the required position in
the Devices window and click on the Enroll option – enrollment
mode is then launched.
4. Press the control button (1) on the siren. The siren is thus
enrolled to required position and the yellow LED goes off.
5. Set the siren properties (see the
Warning: If the battery is low then the siren can´t be enrolled to
the control panel. This status is indicated by the periodical flashing
of the yellow LED each 15 s. It is strictly necessary to wait (usually
a few minutes) until the backup battery is charged to the point when
it is able to transmit the enrolling signal. When the backup battery is
fully charged (permanently lit yellow LED), open the enrollment
mode and then press the control button (1) to transmit an enrolling
signal.
If the siren is unplugged from the electricity then it will be able to
work for 12 hrs from the backup battery. When the backup battery
voltage reaches the critical level, then the siren is turned off to
protect the backup battery against damage.
Internal settings of the siren
Go to the Devices tab in the N-Link software. When you are at
the siren position, use the Internal settings option to open a dialog
window where you can set: (* indicates default settings).
Setting tab:
Acoustic indication of alarms from sections: defines for which
sections the siren should indicate an alarm and system setting.
The default setting is indication for all sections (1, 2, 3, 4).*
Reaction: defines whether the siren should indicate an IW* (internal
warning) or EW (external warning) signal. Alarm indication with siren
chirps can also be completely disabled (other functions remain active).
Siren sound: Intermittent*, Continuous
Maximum siren time: No, 1, 2, 3*, 4, 5 minutes.
During section control: Enabled/Disabled * - if enabled, the siren
chirps once after setting, twice after unsetting and three times when
unsetting after an alarm. It only does so for selected sections.
Other acoustic indication from sections: defines for which
sections the siren should indicate entry/exit delay. The default setting is
indication for all sections (1, 2, 3, 4).*
Higher volume: Enabled/Disabled* - affects only entrance/exit
delay signalling and sounds indicating PG output triggering.
Entry delay: Enabled/Disabled* if enabled, it indicates the entrance
delays of the selected sections.

chapter)
Internal setting
Entry delay when partially set: Enabled /Disabled* if enabled, it
indicates the exit delays of the selected sections when partially set.
Exit delay: Enabled/Disabled* if enabled, it indicates the exit delays
of the selected sections.
Detection of tampering: by the built-in accelerometer the siren
detects its disconnection from electrical socket. Options Disabled,
Always*, During alarm.
Test – by pressing the TEST button you can test the siren function
and the siren reacts to this pressing by 3 s alarm sound.
Signalling PG tab:
Sound indication can be set for each PG output:
No - PG output generates no sound
Slow beeping - slow chirping – 1 per second (for the whole period
when the PG is active)
Quick beeping rapid chirping – 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 s of beeping - 20 s long chirp when the PG is activated
Melody - melody selection
Note:
The siren sound has the highest priority, the chirps during control
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 higher
priority always terminates the chirp with a lower priority.
The default setting is that pressing the siren button (1) during an
alarm mutes the siren and concurrently confirms a person's
presence in the building (a report is sent).
It is possible to change the siren button (1) reaction in order to
function as a panic alarm button in the Devices window in the N-Link
software. In such a case the system responds to the pressing with
triggering a panic alarm in the section to which the siren has been
assigned.
To set the siren to comply with security grade
2 according to the EN50131 norm, use N-Link SW,
the Parameters tab and the option System profiles.
Backup battery replacement
The siren checks the backup battery status automatically.
The current status can be checked by the N-Link software tab
called Diagnostics (current battery status, its voltage when loaded
and unloaded). When a backup battery fault is triggered, then it is
necessary to replace it as fast as possible to avoid siren
malfunctioning.
The control panel must be in service mode (see control panel
installation manual) then it is possible to open the siren cover,
before you start changing the battery. Valid when Detection
of tampering is enabled. Always use a 3.6 V, 170 mAh (BAT-3V6-
N170) backup battery.
Note: If the battery is low (as reported to the control panel)
the siren is not able to fully perform all its functions
Battery replacement procedure:
Battery replacement can only be done
by a person
electrotechnical qualification and only
when the siren is disconnected from
its electrical socket.
1. Unplug the siren from the electrical socket.
2. Unscrew the 4 locking screws on the siren's rear side and remove
the rear side carefully.
3. Take out the PCB from the Front part.
4. Now it is possible to replace the old backup battery. Fix the new
backup battery by the ties and connect it by connector to the PCB.
5. Re-assemble the siren in reverse order of the points (1 – 3)
– be careful, the spring has to be correctly assembled on the LED's
body otherwise the button will not work (1).
