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.
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).

On the FW-C2Z, FW-C4Z and FW-C4EZ only, JW1 & JW2 are connected from 1 to 2 for Initiating Circuit Class B (Style B) operation, and from 2 to 3 for Class A (Style D) operation. JW2 is present on the FW-C2Z. Note that the Class A/B selection affects all Initiating Circuits, and must be used with the correct Configuration DIP Switch Setting.
6.2 ZONE EXPANSION MODULE (Model FW-EZM4) Fig.6: FW-EZM4 Zone Expansion Module Class A / B Selection: JW2 & JW3 are connected from 1 to 2 for Initiating Circuit Class B (Style B) operation, and from 2 to 3 for Class A (Style D) operation.
6.4 DACT / Dialer MODULE (Model FW-DACT) Fig.8: FW-DACT Dialer Module Cable to P8 on the Main Fire Alarm Board. Jumper JW6 on the Main Fire Alarm Module must be removed if a FW- DACT is installed. Note that this module cannot be installed if a City Tie Module is used.
7.0 FIELD WIRING 7.1 GENERAL FIELD WIRING CONSIDERATIONS Because most of the Field Wiring is to the Main Board on the swinging DeadFront, it is very important to properly dress the wires so as not to place stress on either their connection to the boards, or running to conduit. The Figure below shows the required wiring techniques.
Wire devices to terminals as shown. See wiring tables and Appendix A for compatible devices and Appendix C for specifications. Caution: Do not exceed power supply ratings: FW-C2Z, FW-C4Z, total current for Notification Circuits is 2.4 A max. FW-C4EZ, total current for Notification Circuits is 5 A max.

Fig.11a:Main Fire Alarm Module Terminal Connections (continued) EXAMPLES OF BOTH CLASS “A” AND “B” WIRING ARE SHOWN, BUT ONLY ONE CLASS OF WIRING MAY BE USED IN ANY INSTALLATION. Page 17 of 36...
7.3 ZONE EXPANSION MODULE (FW-EZM4) TERMINAL CONNECTIONS Wire devices to terminals as shown. See wiring tables and appendix "A" for compatible devices. See appendix "C" for Module specifications. Fig.12: FW-EZM4 Zone Expansion Module Terminal Connections EXAMPLES OF BOTH CLASS “A” AND “B” WIRING ARE SHOWN, BUT ONLY ONE CLASS OF WIRING MAY BE USED IN ANY INSTALLATION.
7.4 RELAY MODULE ( FW-RB4 or FW-RB8) TERMINAL CONNECTIONS Note that only Relays #1 to #4 are present on the FW-RB4. Fig.13: FW-RB4 / FW-RB8 Relay Terminal Connections Page 19 of 36...
7.5 DACT / Dialer MODULE (FW-DACT) TERMINAL CONNECTIONS See the FW-DACT Manual (LT-639NAP) for connection information. 7.6 POLARITY REVERSAL and CITY TIE MODULE (MODEL: FW-RPM) TERMINAL CONNECTIONS See Appendix for Module specifications. Wire as shown using proper wire gauges. Note that for use in the USA, the installer MUST add an Atlantic Scientific (Tel. 407-725-8000) Model #24544 Protective Device, or similar ULI-Listed QVRG Secondary Protector, as shown.
7.7 POWER SUPPLY CONNECTIONS The power supply is part of the Main Fire Alarm Module and the Chassis. The ratings are: Model FW-C2Z, FW-C4Z: Electrical input ratings: 120 VAC, 60 Hz, 2.0A (Uses 3A in line time delay fuse) Power supply total current: 2.75 A maximum...

8.0 SYSTEM CHECKOUT 8.1 BEFORE TURNING THE POWER "ON": 1. To prevent sparking, do not connect the batteries. Connect the batteries after powering the system from the main AC supply. 2. Check that all Modules are installed in the proper location with the proper connections. 3.

9.1 INDICATORS: Buzzer: The Buzzer is activated by any of the following ... Fire Alarm Steady Supervisory Alarm Steady Trouble On and off at a rate of 20 per minute. If the Buzzer is turned on in response to a Non-Latching Trouble or Supervisory, it will be turned off if the condition causing it goes away and there is no other reason for it to be on.
9.2 CONTROLS: System Reset Switch: The System Reset momentary switch causes the Fire Alarm Control Panel, and all Circuits, to be reset ... Resets all Latching Trouble Conditions Resets all Initiating Circuits Resets the 4-Wire Smoke Supplies Turns off all Notification Circuits Turns off Signal Silence Indicator Turns off Fire Drill Stops and resets all Timers...
9.4 CIRCUIT TYPES: “Circuits” refers to an actual electrical interface, either Initiating (Detection) or Indicating (Signal). “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.
& The selection of Class A/B (Style Z/Y) Notification Circuits is only a matter of how they are wired. See Connection Info. & If Class A (Style D) Initiating Circuits are selected (FW-C2Z, FW-C4Z, FW-C4EZ only), the appropriate Board Jumpers must also be set. Class B Initiating Circuits 1&2 combine to create Class A Circuit #1, and Class B Initiating Circuits 3&4 combine to create Class A Circuit #2.

11.0 WALK TEST OPERATION Walk-Test allows an installer to verify the Initiating Circuit wiring in a system. Walk-Test is entered by pressing and holding the Buzzer Silence and Lamp Test Momentary Switches for at least 5 seconds. Circuits to be tested are identified using the Circuit Disconnect Slide Switches.
