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.
D185 Reverse Polarity Module
The D185 Reverse Polarity Module is a UL Listed
module connecting 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 control panel to a
monitoring station. The D185 operates with either 12 or
24 VDC supply.
The D185 can signal alarm, trouble, and supervisory
conditions (refer to the D185 Installation Manual (P/N:
32906) for details).
Figure 22 shows the module being used to signal alarm
and trouble conditions only. With a third relay, available
from the eight-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 is
programmed as a monitor point. Any alarm interrupts
the voltage to the monitoring station. Placing the D185
in Test Mode causes a MONITOR TROUBLE 4.
