6 INS154-4
1.5 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.
2. Servicing
CAUTION: BEFORE OPENING THE COVER ALLOW AT
LEAST 3 MINUTES AFTER THE LAST STROBE FLASH
Most control panels have a method of testing the siren and strobe, which should be

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.
For safety reasons if it is necessary to inspect the unit, the Self-Activate (S/A) on
tamper function should be disabled before the cover is removed. This is achieved by
using the unit’s unique patented engineer Hold-Off mode. This is invoked by
activating and de-activating the strobe three times within 30 seconds. Most control
panels have a method of testing the strobe, which should be utilised. Failing this the
strobe can be manually activated by connecting the S (STRB) wire to 0V at the
control panel. Hold-Off mode is shown to be active with the tamper circuit secure by
the right LED only flashing.
If the tamper circuit is not opened then Hold-Off mode will automatically start to
cancel after 15 minutes, indicated by the LEDs alternating rapidly to signal that S/A
on tamper will be re-enabled within a further 2 minutes.
Once the outer cover is removed the left LED only will flash to indicate that the
tamper circuit is open.
Please note, it cannot be guaranteed that the battery is fully charged on
installation. When commissioning, the unit may require to be powered from
the control panel for a period of time before the battery is sufficiently
charged for self-activation.
