The IUI-SIR-OD is a self powered siren for outdoor security applications producing a rated power of 90 dBA. This siren is tampered when opening the cover and when removing the base from the wall. The siren has the possibility of a built -in power back up, using a 12 V DC rechargeable battery, as to maintain a constant service in case of a failure of the main power supply. In alarm only the internal battery is required. This effectively protects the charger of the panel when several sirens are powered by it.
