The Best Defense is a Good OffenseThe 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 enunciate 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.Build Your Brand and Your BusinessThe WT4911 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.Secure, Continuous Communication with Added BenefitsThe 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 signaled 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.Features: * Siren output is 105dB * Siren sounds for: Alarms & Squawks * Strobe light functionality to visually indicate alarms * Provides outdoor temperature reading to the WT5500 wireless keypad * Transmits module status including tamper and low battery * Fully supervised * Local and remote test capability * Case and wall tamper * Up to 4 sirens per system
