Product overview

Purpose: Suitable for intelligent two-wire systems, each module's independent address can be selected through a built-in rotary switch, allowing compatible control panels to switch discrete contacts through code commands.

Structure: Contains two sets of isolated Form-C contacts, used as DPDT switches, with rated values in accordance with the table in the manual; The module does not monitor the circuit connections of relay contacts; The module also has an LED indicator controlled by a panel.

Compatibility requirements

Need to connect to a compatible Silent Knight system control panel (specific list can be obtained from Silent Knight).

Preparation before installation

This information is only for a quick reference installation guide. For detailed system information, please refer to the corresponding Silent Knight control panel installation manual.

To install modules in existing operating systems, operators and local authorities need to be notified that the system will be temporarily suspended.

Disconnect the power supply of the control panel before installing the module.

This manual should be left to the owner/user of this device.

Installation method

SK Relay is directly installed on a 4-inch square electrical box (see Figure 2A), and the minimum depth of the box must be 2 inches.

Silent Knight provides surface mounted electrical boxes (SMB500).

Wiring requirements

All wiring must comply with applicable local codes, regulations, and laws.

When using control modules in non power limiting applications, CB500 module barriers must be used to meet UL's requirements for power limiting and non power limiting terminal and wiring separation. The barrier must be inserted into a junction box, and the control module must be placed in the barrier and connected to the junction box (Figure 2A). The power limiting wiring must be placed in the isolation quadrant of the module barrier (Figure 2B).

Install module wiring according to the engineering drawings and corresponding wiring diagrams.

Set the address on the module according to the engineering drawing.

Fix the module to the electrical box as shown in Figure 2A (provided by the installer).

Warning message

All relay switch contacts are in standby state (open) at the factory, but may have been switched to active state (closed) during transportation. To ensure that the switch contacts are in the correct state, the module must communicate with the panel before connecting the circuit controlled by the module.
