Notification Appliance Circuit (NAC) Module - 55000-825ADV
The 55000-825ADV Notification Appliance Circuit (NAC) Module is an addressable module for use with the AX-CTL-
1L, AX-CTL-2 or AX-CTL-4 AX-CTL base card. Each module incorporates an independent, individually
programmable, notification appliance circuit (NAC), providing cost-effective solutions in areas requiring multiple
notification appliance circuits. Each 55000-825ADV allows switching of an external power supply, such as a 24 VDC
regulated power source or audio amplifier to a group of notification appliances.
The 55000-825ADV notification appliance circuit can be wired either Class A or B. Each module also supervises the
wiring for opens, shorts and grounds and reports this status back to the intelligent fire alarm control panel. Typical
input power to the 55000-825ADV would be from the main fire alarm control panel, a power supply booster or an
amplifier.
To increase the already rapid response activation of the 55000-825ADV, each module can be set to a group address,
allowing all 55000-825ADV’s assigned to a common group address to be activated from a single command poll from
the intelligent fire alarm control panel.
An eight position programming DIP switch is provided on each 55000-825ADV module for NAC Module addressing
and wiring classification definition. In additional, a four position programming DIP switch is provided for group
addressing (see figure 14 and 15).
The 55000-825ADV mounts to the front of a standard 4” square or 2-gang electrical outlet box. Displayed on the front
of each 55000-825ADV is a single red status LED which flashes when the device is polled.
Compatible with the Axis
AX
Dynamix I/O Relationship Programming, the 55000-825ADV module can be individually
assigned to activate from any input zone or address. In addition, the 55000-825ADV can be programmed to various
output relationships, timing functions, gated functions, etc. to perform project specific control operations.
