How would you like to offer your customers 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 DSCs 2-Way Wireless Security Suite delivers just thatand so much more.

The WT4911B Wireless Outdoor Siren is a fully supervised wireless siren designed to work with the ALEXOR Wireless Panel. The WT4911B combines form and function to provide improved protection against intruders, before they get the chance to enter the home. With its powerful 100dB sounder, the WT4911B will annunciate unwanted entrance to property and premises. The accompanying strobe light also provides a visual warning and deterrent upon activation. The WT4911B distinguishes between burglar and fire alarm by emitting different sounds for each and indicates arm and disarm squawks.

The WT4911B siren can be installed anywhere outdoors (or even indoors, for those requiring a louder siren) fast and easy. A large surface area on the siren allows for security company logos, increasing brand presence and awareness.

The WT4911B offers 2-way wireless and continuously supervised communication with the ALEXOR Wireless Panel. The signals between the WT4911B and the panel are fully encrypted, prohibiting unauthorized interruption of communication between the two. If the WT4911B siren is disabled or tampered with, ALEXOR will immediately be signaled and the appropriate transmission will instantly be transmitted to the monitoring station. Additionally, one of the other sirens (either indoor or outdoor or ALEXORs onboard siren itself) installed on the system will make up for the absence of the WT4911B. ALEXOR and IMPASSA supports up to 4 sirens.

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 DSCs 2-Way Wireless Security Suite).
