SK-Relay-6 Six Relay Control Module

SPECIFICATIONS

Normal Operating Voltage: 15-32 VDC Stand-By Current:1.45 mA Alarm Current: 32 mA (assumes all six relays have been switched once and all six LEDs solid on) Temperature Range: 32°F to 120°F (0°C to 49°C) Humidity: 10 to 85% Non-condensing Dimensions: 6.8˝ H × 5.8˝ W × 1.0˝ D Accessories: IDP-ACB cabinet and chassis Wire Gauge: 12-18 AWG Relay Current: 30 mA/Relay Pulse (15.6 mS pulse duration) pulse under panel control

BEFORE INSTALLING

If the modules will be installed in an existing operational system, inform the operator and local authority that the system will be temporarily out of service. Disconnect the power to the control panel before installing the modules. This system contains static sensitive components. Always ground yourself with a proper wrist strap before handling any circuits so that static charges are removed from the body. The housing cabinet should be metallic and suitably grounded.

NOTICE: This manual should be left with the owner/user of this equipment.

GENERAL DESCRIPTION

The SK-Relay-6 Six Relay Control Module is intended for use in an intelligent alarm system. Each module is intended for Form-C switching applications, which do not require wiring supervision for the load circuit. A single isolated set of dry relay contacts is provided for each module, which is capable of being wired for either normally open or normally closed for each operation. 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(or 01 to 154 for panels that support 159 addresses). 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 SK-Relay-6 module also has panel controlled green LED indicators. The panel can cause the LEDs to blink, latch on, or latch off.

COMPATIBILITY REQUIREMENTS

To ensure proper operation, this module shall be connected to a compatible Silent Knight system control panel.

All relay switch contacts are shipped in the standby state (open) state, but may have transferred to the activated (closed) state during shipping. To ensure that the switch contacts are in their correct state, modules must be made to communicate with the panel before connecting circuits controlled by the module.

BACKBOX MOUNTING HOLES

The following is a description of the SK-Relay-6 mounting framework:

One or two SK-Relay-6 modules can be installed in a IDP-ACB cabinet•

The IDP-ACB cabinet has a built-in chassis that will accommodate one or two SK-Relay-6 modules.

FIGURE 1: IDP-ACB CABINET

C0234-05

The front SK-Relay-6 module positions of each chassis are offset below the rear SK-Relay-6 module positions so that all of the status indicators are visible. For cabinet dimensions refer to IDP-ACB instruction manual.

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 2: TYPICAL MOUNTING hOLE LOCATIONS

Step 1: Insert the bottom of the SK-Relay-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.

The steps in Figures 4a and 4b 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 a module.

2. 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 3 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 4a and 4b for method two. All necessary screws and standoffs are supplied with the modules.

FIGURE 3: INSTALLATION OF REAR MODULE ONLY, METhOD ONE

Step 1: Insert the bottom edge of the SK-Relay-6 module down into a rear slot

of the chassis.

Step 2: Carefully swing the bottom edge of the board towards the back of the

board until it touches the short standoff attached to the chassis.

Step 3: Align the long standoff with the short standoff and tighten.

FIGURE 4B: INSTALLATION OF SK-RELAY-6 MODULE IN FRONT ChASSIS POSITION

C0245-00

Step 1: Insert the bottom edge of the SK-Relay-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 touchesthe 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.
