NAC as Releasing Device Circuit
The releasing device circuit is typically a NAC programmed to control a releasing device, such as a solenoid or squib. It is fully
supervised and power limited.

Note: When a NAC is configured as a releasing circuit, the End of Line Diode (EOLD) assembly must be installed.
The Potter EOLD part number is 3005012; it must be installed in accordance with the installation manual.
When the Control Panel is configured as a release system and installed according to NFPA 12A or NFPA 2001, the system must
include a mechanical means to manually release the agent.
Maximum Wire Impedance Formula
The maximum wiring impedance is a function of the load being applied. Calculate maximum resistance as follows:
(Total current of all connected devices) x (Wire resistance) <2.05 volts
