Digital Alarm Communicating
Transmitter (DACT) Wiring
• The DACT requires two telephone line connections to
meet NFPA72 requirements. Wire from TB5-3/TB5-4
and TB5-7/TB5-8 to an RJ-11 or other Telcom wiring
block for connection to other telephone equipment. The
DACT will seize control of the telephone line (if neces-
sary) to transmit emergency messages. When wired as
shown, the DACT will properly control access to lines
in an emergency.
• Telephone wiring from public telephone network con-
nects to TB5-1/TB5-2 and TB5-5/TB5-6.
• Wire from TELCO equipment to TB5 using 18 AWG to
24 AWG.
• All wiring is supervised.
• Digital Alarm Communicator Receiver (DACR) com-
patibility is shown in Table 2-4.
• If wiring is routed outside the building, use of a listed
secondary protector is required. Use Simplex Number
2081-9028 or 2081-9044. A protector must be installed
at each building exit/entrance. Each 2081-9028 adds .2
ohm wiring resistance. Each 2081-9044 adds 6 ohms
wiring resistance. Use of the 2081-9044 will signifi-
cantly reduce wiring distance.
