1.0 INTRODUCTION

Introduction :

NAPCO's FW-C2Z, FW-C4Z and FW-C4EZ 24 Volt Fire Alarm Control Panels provide 1,2, 4, or 8 supervised Class
B (UL Style B) Initiating Circuits, or 1,2, 4 supervised Class A (UL Style D) Initiating Circuits, and 2 or 4 supervised
Class A or B (UL Style Z or Y) Notification Circuits. All Circuits are supervised for opens and ground faults, and
Notification Circuits for shorts. Optional Modules include a FW-EZM4 Zone Expansion (required for full capacity in the
FW-C4EZ only), a FW-DACT Dialer or a FW-RPM Polarity Reversal & City Tie Module, and FW-RB4 or FW-RB8
Relay Modules. The two enclosures are flush or surface mountable, and can be used for retrofits and on new
installations.

1.1 Overall Features:

T The small enclosure versions, FW-C2Z, & FW-C4Z have 1, 2, 4 Class B (Style B) Initiating Circuits

respectively. The FW-C2Z & FW-C4Z may be configured as 1 or 2 Class A (Style D) Circuits respectively.
These also have 2 Power Limited Class A/B (Style Z/Y) Notification Circuits with individual trouble indicators.

T The large enclosure version, FW-C4EZ, has 4 Class B (Style B) Initiating Circuits which may be configured

as 2 Class A (Style D) Circuits respectively. It also has 2 Power Limited Class A/B (Style Z/Y) Notification
Circuits with individual trouble indicators. With a FW-EZM4 Zone Expansion, an extra 4 Class B (2 Class A)
Initiating Circuits, and 2 Class A/B Notification Circuits are added.

T Each Initiating Circuit is configurable as a Normal or Verified Alarm. In addition, on a Class B FW-C4Z or FW-

C4EZ, Initiating Circuit 3 may be a Waterflow Zone (as may Initiating Circuit 7 if a FW-EZM4 is installed), and
Initiating Circuit 4 may be a Latched or Non-Latched Supervisory Zone (as may Initiating Circuit 8 if a FW­EZM4 is installed). On a Class A FW-C4EZ with a FW-EZM4, Initiating Circuit 3 may be a Waterflow Zone, and
Initiating Circuit 4 may be a Latched or Non-Latched Supervisory Zone.

T Notification Circuits can be configured as Audible or Visual and as silenceable or non-silenceable. Audibles

may be Steady, Temporal Code, California Code, or March Time.

T Initiating Circuits may be individually Disconnected by a Slide-Switch.
T Configurable Signal Silence Inhibit (disabled or 1 minute), Auto Signal Silence (disabled or 5, 10, 20 minutes) ,

and One-Man Walk Test.

T Subsequent Alarm, Supervisory, and Trouble operation
T 4 wire resettable Smoke Power Supply (100 mA Max.).
T Auxiliary relay contacts for Common Alarm and Common Supervisory (disconnectable), and a Common

Trouble relay.

T Interface for an RTI Remote Trouble Indicator.
T RS-485 Interface for 1 to 3 of FW-RB8 Remote Multiplex Annunciators on FW-C4Z & FW-C4EZ.
T The FW-C2Z and FW-C4Z may use one of optional FW-DACT (Dialer), FW-RPM (City Tie), FW-RB4 or FW-

RB8 Relay Modules.

T The FW-C4EZ may use one of optional FW-DACT (Dialer), FW-RPM (City Tie), and also one of FW-RB4 or

FW-RB8 Relay Modules.

T Slide Switch Controls and LED Common Indicators.
T Easy Configuration via DIP Switches.
T Extensive transient protection

2.0 GENERAL NOTES

Circuits and Zones:

“Circuits” refers to an actual electrical interface, Initiating (Detection), Indicating (Signal), or Relay.
“Zone” is a logical concept for a Fire Alarm Protected Area, and will consist of at least one Circuit.

Often the terms Zone and Circuit are used interchangeably, but in this Manual the term Circuit is used.

Wiring Styles:

Initiating Circuits are configured by default as Class B (Style B). They may be globally (all or none) configured as
Class A (Style D) as described in the Configuration Section. This operation uses odd and even pairs of two-wire Class
B (Style B) circuits to make one four-wire Class A (Style D) circuit, thus cutting in half the number of available Initiating
Circuits.

Notification Circuits may be individually wired as Class A (Style Z) or Class B (Style Y) without affecting the number
of circuits available (see Module wiring instructions).

Note: All Class B (Style B) initiating circuits are 2 wire smoke detector compatible. These circuits are current limited
to 100 mA max. Refer to table on page 32 for a list of compatible smoke detectors.

5.0 MODULE MOUNTING LOCATIONS

The FW-C2Z, FW-C4Z and FW-C4EZ fire alarms come pre-assembled with all components and boards, except for Adder Modules.
Module installation locations are shown below.

Be sure to connect a solid Earth Ground (from building system ground / to a cold water pipe) to the Chassis Earth Ground Mounting
Lug, and to connect the Earth Ground Wire Lugs from the Main Chassis to the ground screw on the Backbox.

Note that a CH-429 Accessory Mounting Plate is required for the FW-C2Z, or FW-C4Z if any Adder Module is to be used. Note that
only one of FW-RB4, FW-RB8, FW-RPM, or FW-DACT Modules may be used. The CH-429 is installed so that the one Module being
used is towards the bottom of the enclosure.

Fig.3: FW-C2Z, FW-C4Z Module Mounting Locations

NOTES:

1. THE CH-429 ACCESSORY MOUNTING PLATE MUST BE INSTALLED SO THAT THE MODULE BEING USED IS
INSTALLED TOWARDS THE BOTTOM OF THE ENCLOSURE. THIS IS AS SHOWN FOR THE FW-DACT OR FW-RPM
AND ROTATED 180 DEGREES FOR THE FW-RB4 OR FW-RB8.

2. ONLY ONE OF FW-DACT, FW-RPM, FW-RB4, OR FW-RB8 MAY BE INSTALLED
