2.13 2.13 The Control Module
The C304 Control Module is an addressable module that supervises and switches power to a Notification
Appliance Circuit. The C304 can be wired as NFPA Styles W, X Y or Z Notification Appliance or Speaker
Circuits. Alternately, the C304 module can be employed as a Form-C control relay.

Connect the MS-9200 Communications SLC Loop to C304 terminals 1 (-) and 2 (+). The C304 occupies
one module address on the Loop. Set the rotary switches on the C304 to the particular Loop address
required.

NFPA STYLE W OR Y NOTIFICATION APPLIANCE OR SPEAKER CIRCUIT NFPA STYLE W OR Y NOTIFICATION APPLIANCE OR SPEAKER CIRCUIT
Connect polarized alarm Notification Appliances or speakers to a single two-wire circuit. NOTE: This circuit
cannot be T-Tapped or branched in any fashion, and must be terminated across the last device by a 47KW ,
1/2-watt ELR (Part # A2143-00). Connect the circuit to C304 terminals 6 (+) and 7 (-). See Figure 2.19.

Connect polarized alarm Notification Appliances or speakers to a single four-wire circuit. Connect the
circuit to C304 terminals 6 (+), 9 (+), 7 (-) and 8 (-).

Connect Notification Appliance power from MS-9200 TB4 terminal 1 to C304 terminal 4 (+24 VDC) and MS-
9200 TB4 terminal 2 to C304 terminal 3 (-24VDC). This power must be supervised by a UL listed Power
Supervision Relay, wired as shown in Figure 2.20.
CODED OPERATION CODED OPERATION CODED OPERATION CODED OPERATION CODED OPERATION
Connect Notification Appliance power from either TB1 (NAC 1 Output) terminals 1 and 4 or TB2 (NAC 2
Output) terminals 1 and 4 to C304 Control Module terminals 3 and 4. Be certain to place an ELR across
the last device on the module (use only one ELR) for Style B operation. Set NAC 1 or NAC 2, which is now
used to drive the C304, for appropriate coded function. Refer to Section 3.2.03 Point Edit for additional
information.
Note: When wiring Style Z, do not install an ELR since one is built into the C304 Control Module.
TEST SWITCH TEST SWITCH
TEST SWITCH TEST SWITCH TEST SWITCH
The C304 Control Module includes a magnetic test switch sensor located near the center front of the
module. Activation of this switch by test magnet P/N M02-04-00 will cause a short circuit indication for the
Style W/X/Y/Z circuit connected to the module.
