This siren/strobe is part of the Alexor 2-way wireless security suite. No wires to run!
Greater Protection. Complete Security: How would you like a security system that provides complete security via a host of devices, including keypads, sirens, detectors and wireless keys, and also supports GSM and IP communications - all of it wirelessly? The new DSC's 2-Way Wireless Security Suite delivers just that, and so much more.
The Best Defence is a Good Offence: The WT4911 Wireless Outdoor Siren is a fully supervised wireless siren designed to work with the Alexor Wireless Panel. The WT4911 combines form and function to provide improved protection against intruders, before they get the chance to enter the home. With its powerful 105dB sounder, the WT4911 will annunciate unwanted entrance to property and premises. The accompanying strobe light also provides a visual warning and deterrent upon activation. The WT4911 distinguishes between burglar and fire alarm by emitting different sounds for each and indicates arm and disarm squawks. The WT4911 siren can be installed anywhere outdoors (or even indoors, for those requiring a louder siren) fast and easy.
Secure, Continuous Communication with Added Benefits: The WT4911 offers 2-way wireless and continuously supervised communication with the Alexor Wireless Panel. The signals between the WT4911 and the panel are fully encrypted, prohibiting unauthorized interruption of communication between the two. If the WT4911 siren is disabled or tampered with, Alexor will immediately be signalled and the appropriate transmission will instantly be transmitted to the monitoring station. Additionally, one of the other sirens (either indoor or outdoor or Alexor's onboard siren itself) installed on the system will make up for the absence of the WT4911. Up to four sirens can be installed on the Alexor Wireless Panel.
An added benefit is that an onboard temperature sensor provides the current outdoor temperature to the accompanying WT5500 wire-free keypad display (also part of DSC's 2-Way Wireless Security Suite).
