8.3.2.2 D184A Local Energy Kit
The D184A is a UL Listed module that connects local energy signaling devices to the D7024 for auxiliary service
operation. Refer to the
D184A Installation Guide
(P/N: 41175) for more information.
8.3.2.3 D185 Reverse Polarity Module
The D185 Reverse Polarity Module is a UL Listed module that connects the control panel with either a single set or a pair
of leased Telephone Company (Telco) lines in NFPA 72 remote station applications. It relays system alarm status
information from the panel to a monitoring station. The D185 operates with either 12 or 24 VDC supply.
The module can signal alarm, trouble, and supervisory conditions (refer to
D185 Installation Manual
(32906) for details).
The diagram below shows the module being used to signal alarm and trouble conditions only. With a third relay (available
from the 8-relay expansion module) and an additional leased line, supervisory conditions can also be signaled.

•
In this example, Relay 1 must be programmed to operate on Alarm (Zone 63) and Relay 2 must be
programmed to operate on Trouble (Zone 62). Input 4 should be programmed as a MONITOR point. Any
alarm will cause the voltage to the monitoring station to be interrupted. Placing the D185 in test mode will
cause a MONITOR TROUBLE 4.
