NC-100(A)

Control Module for
FireWarden Series Panels

Addressable

dn-7000:a2 • A1-360

General

The

NC-100(A) Addressable Control Module provides NOTI-

FIER’s

FireWarden Series intelligent control panels a super-

vised Class B (Style Y) of Class A (Style Z) circuit for

Notification Appliances (horns, strobes, etc.). Addressability

allows the NC-100(A) to be activated, either manually or

through panel programming, on a select (zone or area of cov-

erage) basis.

Features

• Built-in type identification automatically identifies these

devices to the control panel.

• Internal circuitry powered directly by two-wire SLC loop.

The NC-100(A) module requires power (for horns, strobes,

etc.).

• Integral LED “blinks” when communicating, and turns on

steady when activated.

• High noise immunity (EMF/RFI).
• The NC-100(A) may be used to switch 24-volt NAC power.
• Wide viewing angle of LED.
• SEMS screws with clamping plates for wiring ease.
• Direct Decade entry of address: 01 – 99 with FireWarden-

100-2(C), or 01-50 with the FireWarden-50(C).

Applications

The NC-100(A) is used to switch 24 VDC audible/visual power.

Construction

• The face plate is made of off-white heat-resistant plastic.
• Controls include two rotary switches for direct-dial entry of

address setting.

• The NC-100(A) is configured for a single Class B (Style Y)

or Class A (Style Z) Notification Appliance Circuit.

Operation

Each NC-100(A) uses one of the module addresses on a SLC

loop. It responds to regular polls from the control panel and

reports its type and status, including the open/normal/short

status of its Notification Appliance Circuit (NAC). The LED

blinks with each poll received. On command, it activates its

internal relay. The NC-100(A) supervises Class B (Style Y) or

Class A (Style Z) notification or control circuits.
Upon code command from the panel, the NC-100(A) will dis-

connect the supervision and connect the external power sup-

ply in the proper polarity across the load device. The

disconnection of the supervision provides a positive indication

to the panel that the control relay actually turned ON. The

external power supply is always relay-isolated from the com-

munication loop so that a trouble condition on the external

power supply will never interfere with the rest of the system.
Rotary switches set a unique address for each module. The

address may be set before or after mounting. The built-in

TYPE CODE (not settable) will identify the module to the con-

trol panel.
