1.2 Properties
There are four power limited NAC outputs which have the following
characteristics:
- NAC 5 through NAC 8 (Wiring configuration Class B or Class A). In Class A,
the NACs are referred to as NAC 3 and NAC 4.
- Wiring Class configured through configuration tool (no jumpers required).
- Each NAC, whether Class B or A, has a maximum output of 3A @ 24VDC.
- For Class A, the configuration is NAC 3 and NAC 4. There are only two
outputs in Class A.
- All NACs provide coded bell/horn patterns and synchronization for strobes.
- All NACs can be configured as additional Auxiliary outputs or used for
shorting input devices through the Zeus software configuration tool.
- All NACs are supervised for opens, shorts, and overcurrent.
- Each NAC has independent, short circuit, and transient protection.
- EOL values of 2.2K through 24K are acceptable and do not need
configuring through the tool. Class A NAC usage does not require an EOL.
NOTE:
This only applies to NAC supervision. Releasing must be a 24Kohm EOL.
- Use REL-EOL P/N 500-696359 for releasing applications.
- Status LEDs indicates if output is in trouble, or was previously in trouble, in
the case of an intermittent fault.
- Only NAC 5 and NAC 6 (NAC 3 in Class A) can be configured for
Releasing. There is a Manual Disconnect switch that disables all power to
NAC 5 and 6. This is used to prevent accidental energizing of the releasing
zones during servicing. Two switches are required to enable or disable
releasing. When using releasing, the REL-EOL is required for Class B or
Class A and the EOL value can only be 24Kohms.
Integrated P2 loop circuitry for connection to Fire Panel device loop (P2) with
isolation from short circuit capabilities.
Compatibility with Desigo Fire Safety Modular and Cerberus PRO Modular
Systems via the XDLC Card
Ground fault detected at <1kΩ to ground.
