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 control panel to a monitoring
station. The D185 operates with either 12 VDC or
24 VDC supply.
The module can signal alarm, trouble, and
supervisory conditions. Refer to the D185
Installation Manual (P/N: 32906] for details. 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 the example in Figure 15, Relay 1 must be
programmed to operate on Alarm (Zone 63) and
Relay 2 must be programmed to operate on
Trouble (Zone 62). Program Input 4 to operate as a
Supervisory point. Any alarm causes the voltage to
the monitoring station to be interrupted. Placing the
D185 in test mode causes a SUPERVISORY
TROUBLE 4.
