The control panel provides four Notification Appliance Circuits (two Style Y or Z and two Style Y only).<br />
Each circuit is capable of 1.5 amps of current. Total current drawn from all four circuits cannot exceed<br />
2.25 amps. NACs are supervised and power-limited.<br />
Note: Refer to the Device Compatibility Document for suitable devices.<br />
