PT750 Series Wireless Annunciator & Repeater Panel

Model PT750 Series Annunciator / Repeater

Fiberglass & Stainless Steel Enclosures

Model PT750 Annunciator collects sensor data from the main control monitor. Communication is RS485 half duplex between the annunciator and the control panel using a single pair twisted data cable. Maximum length of the cable is 4000 feet. For noisy environment an optional Fiber Optics data converter is used to transmit and receive data over fiber optics cable.

An optional alarm relay module can provide 4 form “C” type relay contacts. The relays are activated whenever the main control panel is in alarm.

Each channel can be programmed to have a sensor tag identifying the location of the sensor. The color graphic touch screen provides easy unit configuration and setup.
