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 FW-
EZM4 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
