GENERAL DESCRIPTION The SC-6 Six Supervised Control Module is intended for use in an intelligent alarm system. Each module is intended for switching applications involving AC, DC, or audio, which require wiring supervision. A common SLC input is used for all modules. Each module has its own address. A pair of rotary code switches is used to set the address of the first module from 01 to 94. The remaining modules are automatically assigned to the next five higher addresses. Provisions are included for disabling a maximum of three unused modules to release the addresses to be used elsewhere. Each module also has panel controlled green LED indicators. The panel can cause the LEDs to blink, latch on, or latch off.

Figure 3: Typical mounting hole locations COMPONENTS Following are descriptions of the SC-6 mounting frameworks. There are two mounting options for SC-6 modules: BACKBOX MOUNTING HOLES • Up to six SC-6 modules can be installed on a CH-6 in a BB-6 cabinet. • One or two SC-6 modules can be installed in a BB-2 cabinet. Chassis The CH-6 chassis is used to mount SC-6 modules in a BB-6 cabinet. It accommodates up to six SC-6 modules in a single cabinet row three modules wide and two modules deep. Figure 4: Mounting the CH-6 chassis The BB-2 cabinet has a built-in chassis that will accommodate one or two SC-6 modules. C0234-00 Figure 1: CH-6 Chassis MOUNT WITH SELF-THREADING SCREWS TO BACK OF CABINET The BB-2 cabinet comes with the chassis already installed, so no mounting is necessary. C0206-00 3. Module Installation There are two methods for installing a module in the rear position of a chassis. Method one is for installation of a rear module only, when no module will be installed in front of it. Refer to Figure 5 for instructions. Method two is for installation of a rear module when another module will be installed in the chassis position in front of it. Refer to Figures 6a and 6b for method two. All necessary screws and standoffs are supplied with the modules.

Cabinets A BB-6 cabinet will house the CH-6 chassis with up to six SC-6 modules installed on it. Refer to cabinet installation documents for dimensions. The BB-2 cabinet houses one or two SC-6 modules on the internal chassis that is part of the cabinet. Refer to cabinet installation documents for dimensions. INSTALLATION STEPS 1. Cabinet Mounting In a clean, dry area, mount the backbox using the four holes provided in the back surface of the cabinet (Figure 3). 2. Chassis Installation The CH-6 chassis is mounted in the BB-6 cabinet. It is shipped with two self-threading screws, which are used to fasten the chassis to the back wall of the cabinet (see Figure 4). D500-50-00 C0236-00 Step 1:Insert the bottom of the SC-6 module down into a rear slot on the chassis. Step 2: Carefully swing the upper edge of the board back towards the back of the chassis until it touches the two standoffs. Step 3:Align two 4-40 screws with the two standoffs and tighten. Step 4: Address and wire the modules according to the instructions in this manual. 2 I56-1802-012 The steps in Figures 6a and 6b describe and illustrate module installation when the rear chassis position and the position in front of it will be filled. Front position installation is possible only if the rear position is filled with another module. 4.A shunt is provided to disable a maximum of three unused modules (see Figure 7). Modules are disabled from the highest address and work downward. If two modules are disabled, the lowest four addresses will be functional, while the highest two will be disabled. For example, if the shunt for Address Disable is placed on “two” and the base address switch is set to 28, the modules will be assigned to 28, 29, 30 and 31, disabling the higher two positions. NOTE: In Class A operation, placing the small shunt on “disable 3” will disable all three addresses. Placing the small shunt on “disable 2” will disable two out of the three addresses. For example, if the address switch is set to 28 and the small shunt is placed on “disable 2”, addresses 30 and 32 will be disabled while address 28 will be enabled. 5.There is a short circuit protection option for each address. The board C0226-00 is shipped with short circuit protection disabled for each address represented by six large shunts on the “Disable Short Circuit Protection” area. To enable short circuit protection for an address, remove the corresponding shunts from the “Disable Short Circuit Protection” area. When enabled, the module will not switch power supply if a short circuit condition exists on a notification appliance circuit. NOTE: Short circuit protection may only be enabled if power supply monitoring is enabled. Figure 7: Figure 6a: Installation of SC-6 module in a rear chassis position, method two 1 Step 1: Insert the bottom edge of the SC-6 module down into a rear slot of the chassis. Step 2: Carefully swing the upper edge of the board towards the back of the chassis until it touches the short standoff attached to the chassis. Step 3: Align the long standoff with the short standoff and tighten. Figure 6b: Installation of SC-6 module in front chassis position 3 6.There is a power supply monitor that must be enabled to facilitate short circuit protection (see Figure 7). The module is shipped with power supply monitoring enabled represented by six large shunts on the pins of the “Enable Power Supply Monitor” area. NOTE: Power supply monitoring should not be used for audio applications. The short circuit protection feature is also not available for audio applications. NOTE: The XP6-C does not provide ring back when used as a firefighter telephone circuit. NOTE: This feature is not for use with all Fire Alarm Control Panels. Please consult with Technical Services before enabling this feature. NOTE: Place unused shunts on single pin to store on board for future use. NOTE: SLC wiring is the top terminal block, notification appliance/power supply is the bottom. NOTE: Power must not be applied to the unit when changing functionality of the shunts. NOTE: Whether in Class B or Class A wiring, power supply monitoring and short circuit protection must be enabled on the NAC circuits that are sharing a power supply. NOTE: Short circuit protection can only be disabled if a power supply is not being shared by multiple NACs. WIRING NOTES • Power-limited circuits must employ type FPL, FPLR, or FPLP cable as required by Article 760 of the NEC. C0237-00 2 1 Step 1: Insert the bottom edge of the SC-6 module down into a front slot of the chassis. Step 2: Carefully swing the upper edge of the board towards the back of the chassis until it touches the 11/4˝ (31.75mm) standoffs installed on the rear module. Step 3: Align two 4-40 screws with the two standoffs and tighten. Step 4: Address and wire the modules according to the instructions in this manual. WIRING NOTE: All wiring must conform to applicable local codes, ordinances, and regulations. 1.Install module wiring in accordance with the job drawings and appropriate wiring diagrams. 2.All wiring to the SC-6 is done via terminal blocks. In order to C0225-00 properly make electrical connections strip approximately 1/4˝ of insulation from the end of wire, sliding the bare end of the wire under the clamping plate screw. 3.Set the address on the modules per the job drawing. Use the rotary code switches to set the address of the first module (between 01 and 94). In Class B operation, the remaining modules are automatically assigned to the next five higher addresses. For example, if the base address switch is set to 28, the next five modules will be addressed to 29, 30, 31, 32, and 33. • For easier wiring, assign all power-limited wiring to one side of the enclosure rather than alternating with non power-limited. NAC Wiring and Supervision For Class B, Style Y applications (figures 8, 9, and 12 are typical): connect the positive terminal of the notification appliance(s) to the NAC+ terminal and the negative device terminal to the adjacent NAC- terminal. Connect one (for each NAC) of the supplied EOL resistors across the NAC+ and NAC- wires, at the ends farthest away from the NAC terminal of the SC-6. For Class A, Style Z applications (figures 10, 11, and 13 are typical) wire the NACs per table 2. The A/B select shunt must be removed prior to connecting the SC-6 to the SLC. The EOL resistors should not be used. The SC-6 is capable of supporting 3 Class A, Style Z NACs. The SC-6 will only respond at the base address, base address +2, and base address +4 (assuming no addresses have been disabled). In Class A operation, a maximum of three Class A circuits are available. For example, if the base address switch is set to 28, 30 and 32 will be automatically assigned to the modules while 29, 31 and 33 are available to be used for other modules on the SLC. For Class A and B operation, DO NOT set the lowest address above 94, as the other modules will be assigned to nonexistent addresses.

The EOL relay coil should always be connected at the external power supply input of the module which is connected to the ends of the wires which are farthest from the power supply. The EOL relay contacts should always be connected in series with the NAC wiring of the same module. The EOL relay coil should be connected across the PS+ (red wire) and PS- (black wire) if it is connected at T0 – T5. The EOL relay coil should be connected across adjacent pins (red – even pin#, black – odd pin#), of the same connector, if T10 – T16 are used. If the supply is an audio amplifier then the points, where the EOL relay coil would normally be connected, should be connected to the amplifier supervision EOL device (figures 12 and 13 are typical). Power Supply Wiring and Supervision Table 3 gives an overview of how the power connectors, T0–T5 and T10–T15, are interconnected by the circuit board (PCB). The external supply connection points, at T0–T5, are marked by PS– and PS+ on the PCB legend. Pin 1 is indicated by a dot next to T10–T16. The odd pins, on T10–T16, always connect to PS– pins (e.g. PS–, of the +0 NAC, is connected to T10–1 and T11–1). The even pins always connect to PS+ pins (e.g. PS+, of the +5 NAC, is connected to T15-4 and T16-2). All wiring must be in accordance with the NEC, NFPA 72 and all other applicable codes and standards. All external power supplies must be voltage regulated with battery back-up. All external power supplies, audio amplifiers, EOL relays, and notification appliances must be UL listed for fire protection signaling applications.

All power supplies, external to the cabinet (in which the SC-6 is housed), should be connected to T0–T5 which are suitable connectors for field wiring. The 1 x 4 terminal blocks, shown on page 1, should be used to make these connections. All NACs can be wired to be powered by separate external supplies (figures 8 and 10 are typical), or a single supply (figures 9 and 11 are typical) can be shared among multiple NACs. If a supply is to be shared, between NACs wired to a common PCB, use the short power supply jumpers shown on page 1. The jumpers can be used on T11–T15. Refer to Table 4 for jumper functions. When multiple (2 or more) NAC circuits share a power supply, the wiring for the power supply must be in conduit and 20 feet or less from the SC-6 board.
