The HDACT-100 Digital Alarm Communicator Transmitter/Dialer Module allows the HCP-1000 Fire Alarm Control Panels to use one or two phone lines to call a Central Station and report a local Alarm, Trouble or Supervisory condition. Requiring two supervised telephone lines, the HDACT-100 can be programmed to use the Security Industry Association (SIA) Digital Communication Standard (DCS) and Ademco Contact ID protocols. The HDACT-100 is powered by the HCP- 1000 Fire Alarm Control Panels and communicates with them via an RS-485 Interface. The HCFG-100 Configuration & Diagnostic Tool is required to program the HDACT-100.
