To install the 7644-L8 for polarity reversal:
1. Wire the 7644-L8 to the control panel as shown in Figure 4.50. Do not install an EOL resistor on the terminals of the NAC circuit
used.
2. Program the NAC circuit as a notification circuit. See Section 9.5.4.
3. Map the group to activate constant on from the zone event.
4. Program the output group characteristics as non-silenceable and reverse polarity.
