Backlight Wiring Options
The backlight is wired for constant use from the factory; It is also possible to wire the backlight to the control panels outputs for different
operation; for example,
•
the Backlight could be wired to activate with the strobe,
•
or could be wired to a timer so that it only operates at certain times of the day or night. Many options are available depending
on the capability of the control equipment.
Installing Multiple Wired Units
The following diagram illustrates how to wire multiple units together:
If the first unit is opened it will self-activate and a tamper will be signalled to the control panel. If the second unit is opened both units will self-
activate and a tamper will be signalled to the control panel.
If more than one unit is connected to an installation, the current demand may exceed the rated current output of the control panel. This can be
avoided by selecting Low Current (LC) or SCB mode on one or more of the connected units.
Low Current Mode (wired units only)
Low current mode* allows the sounder current draw from the control panel to be reduced whilst maintaining significant alarm volume. To select
low current mode, ensure the SAB/SCB jumper is in the SAB position and move the LC jumper to the Low Current on position. Details on current
draw can be found in the technical specification (section 4).
* Not available on all models
SCB Mode (wired units only)
In SCB mode the unit draws the majority of its sounding current from the built-in battery rather than from the control panel. Although volume is
somewhat reduced, lowering the current demand on the control panel will enable the connection of additional sounder units.
To select SCB Mode, the unit
should first be powered from the built-in battery by either using the jumper included on some models or by
connecting the red battery wire from the “N/C” (No Connect) terminal to the “B” terminal. The unit will automatically enter Hold-Off mode
to disable Self-Activate (S/A) on tamper, this will prevent the unit from self-activating until both the tamper circuit is closed and power is supplied
from the control panel. Move the SAB/SCB jumper to the SCB position before the unit is connected to the control panel.
If the tamper circuit is closed and the unit is powered by the battery only, the right LED will flash quickly to signal that the
unit cannot self-activate until power has been supplied from the control panel. This
When selecting SCB mode the battery must be connected before power is supplied from the control panel. If a unit is
powered from a control panel with SCB mode selected but without the battery connected, the unit will not operate
correctly due to the lack of power provided.
The built-in battery will only be partially charged on delivery.
Commissioning
Most control panels have a method of testing the siren and strobe, which should be utilised for final testing. Failing this, simply arm the system
and cause an alarm to confirm correct operation. Temporarily disconnect the positive supply to the unit at the control panel to confirm that the
sounder self-activates.
The strobe does not self-activate.
Some control panels have an option to select the sounder cut-off time. The unit will sound for either 15 minutes or for the
panel cut-off time, whichever is the shorter.
Remove tamper wire from MSW 2 on first unit
and connect to spare core. On second unit
connect spare core into MSW 1.
