completed.
The control panel provides two Style Y (Class B) Releasing Circuits, which are nonpower-limited.
Note: All wiring must follow the requirements as specified under "Power-limited Wiring Requirements" on page 17.
Each circuit is capable of 1.5 amps of current. Total current drawn from both Releasing Circuits and both
NACs (see "Notification Appliance Circuits" on page 20) cannot exceed 2.25 amps.
• UL listed and FM approved releasing devices must be used.
• Unused circuits must be connected with a dummy load as shown.

Wiring must be configured to maintain a minimum voltage of 20.4 VDC on releasing Circuits. Calculation
of maximum allowable resistance:
Rmax =
20.6 VDC – 20.4 VDC

Where:
Rmax = maximum allowable resistance of wiring
Is = Solenoid current
