Self-powered bidirectional 868MHz radio outdoor siren, complete with transceiver and shatterproof galvanized metal protection.

To be combined with the 7.5V - 8Ah battery art. 4239.

Self-powered outdoor radio siren (868MHz / bidirectional) complete with transceiver and shatterproof galvanized metal protection.

White in color with transparent orange background, the siren has an extremely compact and slim design which, together with cutting-edge technology, allows excellent performance to be achieved with maximum energy savings: high sound pressure, high efficiency signaling LEDs.

The siren is completely managed by a microcontroller which verifies all the conditions and appropriately reports them to the control unit via radio communication and is protected against opening and tampering; further protection is ensured by the shatterproof metal under-cover.

The siren can be powered in two different ways: - with the 4239 alkaline battery (not included) of 7.5Vdc - 8Ah - with external power supply 391851 (not included) of 12Vdc - 0.5Ah and a rechargeable buffer battery of 6Vdc - 1, 2Ah
