4.15.3 NFPA 72 Polarity Reversal
Note: Intended for connection to a polarity reversal circuit of a control unit at the protected premises having 
compatible rating.
4.15.3.1 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 
4-42. This diagram also shows how to connect the 5220 to the remote indicator. Do not 
install an EOL resistor in the terminals of the Flexput circuit used for this application.
3. Connect earth ground wire to the 5220 chassis with mounting screw.
4. Program the Flexput circuit used as a notification circuit, continuous and non-silencing. 
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 receiving unit. Maximum loop 
resistance is 3k ohm.
