Overview
Description
1.4 Description
The Universal Digital Alarm Communicator/Transmitter (UDACT-2) may be used with a variety of control panels. The UDACT-2 trans-
mits system status to UL Listed Central Station Receivers, using modular jacks to interface primary and secondary phone lines to the
public switched telephone network. The UDACT-2, which is compact in size, mounts internally in some panels or externally in a sepa-
rate enclosure. EIA-485 annunciator communications bus and 24 volt (nominal) connections are required. Install HWF2A-COM or
HWF2V-COM IP Digital communicators alongside the UDACT-2 to provide a secondary transmission path in lieu of a second phone
line, per UL 864 10th edition requirements (41.3.2.9). The UDACT-2 is compatible with the following panels and network annunciators:
