Essential Info

This outdoor siren is fully wireless and is designed for installation in areas in which wiring action is difficult or impossible. The siren is powered by an external 9VAC adapter and non-rechargeable backup battery, enabling very a long operation time without replacing the battery. Once the alarm is triggered, the siren produces a strong alarm noise and emits a flashing light to deter intruders and guide police and other help to the site. Two types of alarm indicators can be produced from the siren, helping you distinguish between emergencies such as burglary or fire.

Tamper protection prevents burglars and other intruders from opening the siren's cover or removing the siren from the wall. The siren is also fully supervised and can act as a 2-way communication device. It periodically transmits its status signal to the alarm system. The Outdoor Siren reports a low battery message to the alarm system when the battery is about to drain to make the user aware. After low voltage is reported, at least 2 siren alarms are possible before the siren is totally inactive.

This siren is compatible with control panels such as PowerMax Pro, PowerMaxComplete, PowerMaxExpress, or Visonic newer panels (not compatible with PowerMax+ and PowerMax control panels).
