Nfpa 72 Polarity Reversal; Using The 5220 Module - Honeywell SILENT KNIGHT RPS-2000 Installation And Operation Manual

IFP-2000 Installation Manual

4.15.4 NFPA 72 Polarity Reversal

Note: Intended for connection to a polarity reversal circuit of a control unit at the protected premises having
compatible rating.

4.15.4.1 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:
Alarm:
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
4-45. 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 as a notification circuit, Refer to Section 9.5.2. Assign this
flexput to an output group that is mapped to activate with non silenceable constant output
in response to a system general alarm condition.
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.
Intended for connection to a Polarity Reversal
circuit of a Remote Station receiving unit having
compatible ratings.
