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.
