3.12 DACT Phone Lines
Models HCA-2D, HCA-4D and HCA-8D have a built-in Digital Alarm Communicator Transmitter (DACT).
These models have 2, RJ-45 phone line connectors used to wire the incoming telephone lines and pass
through any local premises phone connections that are shared with the DACT. See figure 3.11 for wiring
details.
IMPORTANT:
The HCA DACT must be the first device connected on the incoming telephone lines and all
local premises phones must be located on the phone wiring identified as Phone Ring and Phone Tip in the
diagram below. Only direct connections to the Telco should be wired to the Telco Ring and Telco Tip in
order for the DACT to be able to properly seize control of the telephone line when it needs to report.
