Cameron & Co DS-CS-DSC491BT Li-MnO2 battery

This 3.6V 14.5Ah lithium manganese dioxide battery powers DSC Impassa wireless sirens including models WT4911, WT4911B, WT4911R and WT8911. It replaces original part numbers ER34615M-T1 and WT4911BATT for direct compatibility.

Single battery unit replaces original siren power

The package contains one black battery measuring 62.30 x 34.50 x 33.20 mm. No additional cables, mounting hardware or software are included, so installers must reuse existing connections and brackets from the removed cell.

14500mAh capacity supports long-term siren standby

The 52.20Wh energy rating provides extended operation for wireless outdoor sirens in normal alarm cycles. Systems requiring higher voltage, greater capacity or rechargeable chemistry will need a different power source not covered by this model.

Questions about this item

When will the 14.5 Ah Li-MnO2 cell need replacement in a DSC Impassa WT4911 siren?

The battery is a primary lithium-manganese dioxide cell rated at 14.5 Ah; it cannot be recharged, so it must be replaced once the siren indicates low voltage or after the service life specified by DSC for the WT4911.

What capacity limit appears first during continuous alarm operation?

The 14500 mAh capacity at 3.6 V delivers 52.20 Wh total energy; sustained high-current draw from the siren will deplete this finite capacity before any thermal or voltage-cutoff limit is reached.

Does the 62.30 x 34.50 x 33.20 mm pack generate noticeable heat or noise during all-day standby?

Li-MnO2 chemistry has very low self-discharge and no moving parts, so the pack remains silent and stays at ambient temperature during extended standby in the WT4911 or WT8911 siren.
