Control Panel Installation
Using the Addressable Relay Module for City Box Connection
4.17.1 NFPA 72 Polarity Reversal
Using the 5220 Module
When the 5220 is wired and programmed for polarity reversal, it reports alarm and trouble events to a remote site. Alarms will
override trouble conditions and it will not be possible to reset the remote indicator until the condition is cleared and the control
panel is reset.
If an alarm condition occurs, the alarm relay will close, overriding the trouble condition.
Standby Current: 100 mA, 24 VDC
Alarm: 100 mA, 24 VDC
To install the 5220 for polarity reversal, follow the steps below:
1.
Locate the knockout on the right side of the control panel cabinet to connect the 5220 using a short piece of conduit (must
not exceed 20 feet in length).
2.
Wire the 5220 to the control panel using the four-wire pigtail provided as shown in Figure 4.47. This diagram also shows
how to connect the 5220 to the remote indicator. Do not install an EOL resistor in the terminals of the NAC circuit used
for this application.
3.
Connect earth ground wire to the 5220 chassis with mounting screw.
4.
Program the NAC circuit used as continuous and non-silencing. Refer to Section 9.5 for point programming, Section 9.4
for group settings, and Section 9.3 for zone settings and mapping. It is not possible to reset the remote indication until you
clear the condition and reset the control panel.
5.
If necessary, adjust loop current using the potentiometer (R10) on the 5220 board. Normal loop current is 2-to-8 mA with
a 1k ohm remote station protected premise unit. Maximum loop resistance is 3k ohm.

Using the 7644-L8 Module
When the 7644 is used for polarity reversal, it allows the alarm and the trouble events to be reported to a remote site. The
Alarms will override the trouble conditions and it will not be possible to reset the remote indicator until the condition is cleared
and the control panel is reset.
NOTE:
Intended for connection to a polarity reversal circuit of a control unit at the protected premises having compatible rating.
Note:
NAC circuit 2 and Relay 2
used as examples. Any
NAC circuit and either
relay 1 or relay 2 could
be used.
