Product Description: 

 The DET-16 is an indoor mounted sixteen-zone solid state telegraph transmitter that employs a unique code for each zone. It includes a CAM lock, display and keypad, AC transformer, standby battery and built-in charger. The unit is housed in a steel enclosure suitable for indoor mounting. Telegraph codes unique to each of the sixteen zones for Alarm, Trouble, and Secure, Low Battery, & AC Power Failure are transmitted over 100 milliampere circuit using positive non-interfering successive (PNIS) line current detection to avoid clashes between more than one transmitting box. Automatic ground return, a watchdog timer, and a software selected internal trouble buzzer assure continued main system operation and operator notification in the event of box failure.  The Telegraph Loop Input is Lightning Protected by an Integrated Gas Tube. NFPA-72 compliant.
