DSC Replacement Battery Indoor Siren

DSC Replacement Battery Indoor Siren is a D-size, 3.6 volt, Lithium Thionyl Chloride Battery used to power the Wireless Indoor Siren. Estimated battery life (assuming proper use) is 3 years. Whether you are replacing or installing the DSC Replacement Battery in the Indoor Wireless Siren, you must follow certain directions.

Failure to follow instructions during this installation process may damage your battery, and your siren may not work.

When dealing with this certain type of battery, it must go through a de-passivation mode. The purpose is to precondition the battery so that it won’t drop below the minimum voltage of the device once a load has been applied.  This is done by advancing the discharge past the point of the voltage dip.

Before connecting your battery in the siren, please read and follow theses instructions:

Hold the tamper switch down and plug in the battery (continue holding tamper).
Continue to hold the tamper switch down for 10 seconds and then release. Once the tamper switch is released, the strobe lights on the DSC Wireless Indoor Siren will flash different patterns to indicate that it is in de-passivation mode.

When de-passivation is complete; the strobe lights will shut off and the siren will begin to beep 3 times every 5 seconds. (Note: It can take the unit up to 30 minutes to fully de-passivate.  If the unit could not de-passivate the battery at the end of 30 minutes, the unit will stop trying and begin to beep once every 5 seconds.

When the system begins to beep 3 times every 5 seconds, then press and release the tamper switch on the unit.  At this point, the DSC Wireless Indoor Siren Replacement Battery should flash the strobe lights and beep 6 times.  The unit is now in the normal power up stage.

The DSC Wireless Indoor Siren Replacement Battery is now ready. You enrolled into your DSC Wireless Alarm Panel. Or you return to service.
