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

2Mounting
The NAC module (1A/2B) FCI2011 is installed on the periphery board as shown and
screwed onto the back box. Slot X901 is also used for the releasing module.

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.

for NAC 2 class A or NAC 2-1 class B
Errors of the power PC are displayed on the PMI & mainboard when degraded mode is
activated.
Switching on the degraded mode function of the NAC circuit 2 class A or
circuit 2-1 class B
X602 Jumper position Function Meaning
3 - 2 Disable degraded mode for
NAC 2 class A or NAC 2-1
class B.
Circuit will not activate the notification appliances if
degraded mode is activated and an alarm is present.
1 - 2 Enable degraded mode for
NAC 2 class A or NAC 2-1
class B.
