PRODUCT INFORMATION
The Traditional Zone module provides eight Class B (Style B) traditional direct connect Initiating Device Circuits (IDC) for compatible 2-wire smoke detectors and dry contact initiating devices. Four of the eight IDCs may be converted to Class B (Style Y) Notification Appliance Circuits (NAC). Each pair of NAC circuits may be configured to provide a 24 VDC or signals from an external source for audio and telephone applications.

Each IDC may be set for latching/non-latching operation and verified/non-verified operation. Each IDC can support up to 30 model 6270B photoelectric smoke detectors or 50 model 6250B ionization detectors. Each NAC is rated at 24 VDC@ 3.5Aor 70 Vrms@100W. 24 VDC power for the notification appliances is available directly from the rail chassis. NOTE: Each NAC pair is limited to a total of 3.5 A per two circuits. When the rail chassis is used as the 24 VDC source, the module is limited to a 7 A total current draw. Input terminals are provided to supply the external signal source. The Traditional Zone module requires one connection on the rail chassis and is secured to the assembly using snap rivet fasteners. All field wiring connections to the Traditional Zone module are made via plug-in connectors, permitting termination of field wiring without the module installed in the enclosure. The plug-in connectors and snap rivet mounting also facilitate rapid remove and replace troubleshooting without the use of tools. The module features a hinged front panel for mounting displays or a blank protective faceplate.
