Please Note: The DSC WLS912-433 wireless glassbreak detector has been discontinued and replaced by the WLS922L-433 model number.

DSC WLS912-433 Product Description:


The DSC WLS912-433 is a wireless glassbreak detector designed to detect the sound produced by the shattering of framed glass. It is an advanced acoustic glassbreak detector that uses Dynamic Signal Processing (DSP) to provide accurate detection of plate, laminated, wired (safety) and tempered glass types, while rejecting common false alarm sounds. The WLS912-433 has a built-in RF transmitter to establish a supervised, one-way communications link with a DSC wireless security system.

We recommend backing up your security system's perimeter protection with full interior protection. If an intruder breaks the glass of a window or door that is protected by a contact and comes through the open pane without opening the door or window, the contact will never be tripped. Interior protection acts as a second layer of protection to ensure that this type of entry will still trigger an alarm.

The WLS912-433 wireless glassbreak detector is an excellent choice for interior protection. The wireless door window contact will trigger an alarm if the door or window is opened, while the glassbreak detector will back up that protection and trigger an alarm if the door or window's glass is broken. Glassbreak detectors are better interior protection devices than motion detectors when protecting homes with large pets or when your DSC wireless security system's "stay mode" will frequently be used.
