The Model DXS-91 Supervised Glass Break Detector Transmitter is a glass break detector with a built-in transmitter designed for use with Linear’s DXS and DX Format receivers. When breaking glass is detected, the transmitter sends a digitally coded signal to its companion receiver/control.
The digital DX code format features more than one million possible codes. Each transmitter is precoded at the factory to a unique code so no field coding is required. The DXS-91 can send three different signals: alarm, low battery and status.
The unit is powered by two 3-volt lithium batteries. These batteries will last for approximately two and one half years under normal climatic conditions. If the battery voltage drops below a preset level, a low battery signal is sent with every alarm or test transmission.
