1Description

The notification appliance expansion module (NAC) provides an additional class A

circuit or 2 additional class B circuits. Each class A circuit or each of the two class B

circuits has a rating of 3 A. The header is connected to X901 on the periphery board.

The same jumpers have to be configured on the card as with the periphery board for

class A/B circuit selection and degraded mode. All jumpers must be configured, and

the module in place on X901 before power is applied to the system.

Properties

●Additional NAC circuits with 3 A power for one class A circuit or 3 A for each class

B circuit

●Protected against voltage surge and shorted outputs

●Circuit monitored for short, open, and ground fault

●Ground faults detected at <1 kΩ

●Circuits are power limited

1. Plug the NAC module (3) into slot X901 on the periphery board as shown.

2. Fasten the NAC module to the threaded standoffs (2) in the back box using the two

fixing screws (4).

3. Wire up the NAC module according to the pin assignment.
