Specifications

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

Before Installing

This information is included as a quick reference installation guide. 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.

General Description

The CR-6A 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 four unused modules to release the addresses to be used elsewhere. Each CR-6A module also has panel controlled green LED indicators. The panel can cause the LEDs to blink, latch on, or latch off.

Included Components:

• (6) 1 x 3-terminal blocks
• (1) 1 x 4-terminal block
• (2) 1.25" (32mm) standoffs
• (4) Machine screws
• (2) Nuts

Compatibility Requirements

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

Components and Mounting

Following are descriptions of the CR-6A mounting frameworks. There are two mounting options for CR-6A modules:

CH-6A Chassis

The CH-6A chassis is used to mount CR-6A modules in a BB-6A cabinet. It accommodates up to six CR-6A modules in a single cabinet row, three modules wide and two modules deep. (See Figure 1.)

Figure 1. CH-6A Chassis: A diagram showing the CH-6A chassis, a metal frame designed to hold multiple CR-6A modules. It indicates it accommodates up to six modules in a 3x2 arrangement within a BB-6A cabinet.

• Up to six CR-6A modules can be installed on a CH-6A in a BB-6A cabinet.
• One or two CR-6A modules can be installed in a BB-2A cabinet.

BB-2A Cabinet

The BB-2A cabinet has a built-in chassis that will accommodate one or two CR-6A modules. (See Figure 2.)

Figure 2. BB-2A Cabinet: An illustration of the BB-2A cabinet, a smaller enclosure featuring an integrated chassis capable of holding one or two CR-6A modules.

The front CR-6A module positions of each chassis are offset below the rear CR-6A module positions so that all of the status indicators are visible.

Cabinets

A BB-6A cabinet will house the CH-6A chassis with up to six CR-6A modules installed on it. The BB-2A cabinet houses one or two CR-6A 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. (See Figure 3.)

Figure 3. Typical Mounting Hole Locations: A diagram illustrating the standard mounting hole locations on the back of a cabinet or backbox, used for securing the unit to a wall or surface.

2. Chassis Installation

The CH-6A chassis is mounted in the BB-6A cabinet. It is attached to the two PEM studs on the back wall of the cabinet with two 8-32 hex nuts. The hex nuts are included with the chassis. (See Figure 4.)

Figure 4. Mounting the CH-6 Chassis: A visual guide showing how to attach the CH-6A chassis to the internal PEM studs of a BB-6A cabinet using two 8-32 hex nuts.

The BB-2A cabinet comes with the chassis already installed, so no mounting is necessary.

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.

Method One: Rear Module Only

Figure 5. Installation of Rear Module Only, Method One: A step-by-step visual representation of installing a CR-6A module into a rear slot of a chassis when no module will be placed in front of it. Steps involve inserting the module, swinging it back to touch standoffs, and securing with screws.

1. Insert the bottom of the CR-6A module down into a rear slot on the chassis.
2. Carefully swing the upper edge of the board back towards the back of the chassis until it touches the two standoffs.
3. Align two 4-40 screws with the two standoffs and tighten.
4. Address and wire the modules according to the instructions in this manual.

Method Two: Rear Module with Front Module

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 a module.

Figure 6a. Installation of CR-6A Module in a Rear Chassis Position, Method Two: Illustrates installing a CR-6A module into a rear slot when another module will occupy the front slot. Steps involve inserting into the rear slot, swinging the bottom edge to a short standoff, and aligning with a long standoff.

1. Insert the bottom edge of the CR-6A module down into a rear slot of the chassis.
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.
3. Align the long standoff with the short standoff and tighten.

Figure 6b. Installation of CR-6A Module in Front Chassis Position: Depicts installing a CR-6A module into a front slot. Steps involve inserting into the front slot, swinging the upper edge to touch standoffs on the already installed rear module, and securing with screws.

1. Insert the bottom edge of the CR-6A module down into a front slot of the chassis.
2. Carefully swing the upper edge of the board towards the back of the chassis until it touches the 1.25" (31.75mm) standoffs installed on the rear module.
3. Align two 4-40 screws with the two standoffs and tighten.
4. Address and wire the modules according to the instructions in this manual.

Wiring and Programming

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. Make electrical connections by stripping approximately 1/4” (6.35mm) of insulation from the end of the wire, sliding the bare end of the wire under the clamping plate, and tightening 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 (or 01 and 154 for panels that support 159 addresses). 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. DO NOT set the lowest address above 94 (or 154 for panels that support 159 addresses), as the other modules will be assigned to nonexistent addresses.
4. A dip switch is provided to disable a maximum of four unused modules. 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 dip switch 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.

NOTE: Power must not be applied to the unit when changing functionality of the dip switches.

NOTE: The CR-6A must have power cycled for dip switch changes to take effect.

NOTE: All references to power limited represent "Power Limited (Class..."

Figure 7. Wiring and Programming the CR-6A Module: A detailed diagram showing the CR-6A module's connections. It includes sections for Relay Connections (COMMON, NC, NO), Communication Line (twisted pair recommended, 29 VDC MAX), power input from panel/previous device, and connection to the next device. It also shows the Address Disable dip switches (labeled 1-4) and a representation of the rotary code switches for setting the module address.

Notes:

• The relay contacts on the CR-6A may be connected to either a power-limited or non power-limited source; this wiring must remain separated by at least 0.25" (6.35 mm) from all power-limited wiring.
• Power-limited circuits must employ type FPL, FPLR, or FPLP cable as required by Article 760 of the NEC.
• Installation and wiring requirements shall be in accordance with CSA C22.1 and ULC S524.
• For easier wiring, assign all power-limited wiring to one side rather than alternating with non power-limited.
