Notification Appliance Circuits
The control panel provides two Notification Appliance Circuits (Style Y). Each circuit is capable of 1.5
amps of current. Total current drawn from all four circuits cannot exceed 2.25 amps. NACs are supervised
and power-limited.
Note:
Refer to the Device Compatibility Document for suitable devices.
For details on how jumper configurations affect panel functions see "Supervisory Configuration" on page
20.
• For DIP switch configuration, see "Setting Mode of Operation" on page 27.
• For non-silenceable service on Initiating Zone #1, see "Non-Silenceable Service" on page 32.
