In addition, its compact design allows one or two modules to be installed inside a compatible IDP-ACB cabinet, simplifying both new installations and system expansions.

Product Functions

The Silent Knight IDP-RELAY-6 supports commercial fire alarm systems by providing:

• Six independently programmable Form C relay outputs
• Addressable relay control
• Flexible equipment control through compatible fire alarm panels
• Individual LED status indication for each relay
• Rotary address switch configuration
• Support for HVAC, door holders, smoke control, and auxiliary equipment
• Reliable operation with compatible Silent Knight fire alarm systems

Electrical & System Information

The IDP-RELAY-6 operates with compatible Silent Knight intelligent fire alarm control panels using the system’s Signaling Line Circuit (SLC). Furthermore, each relay can be individually programmed to respond to specific events, zones, or system conditions.

The module provides six dry Form C relay contacts for normally open or normally closed applications. Up to three unused relay circuits may also be disabled to simplify programming and installation. Always verify compatibility before installation.

Features

Six Form C Relay Outputs

The IDP-RELAY-6 provides six independently controlled Form C relay contacts. As a result, a single module can manage multiple control functions throughout the fire alarm system.

Flexible Relay Programming

Each relay can be programmed independently through the compatible Silent Knight control panel. Consequently, installers can configure outputs for a wide variety of building control applications.

Individual LED Indicators

Each relay includes its own LED status indicator. Therefore, technicians can quickly identify relay activity during installation, testing, and maintenance.

Rotary Address Switches

Rotary decimal switches simplify address assignment without requiring additional programming tools. In addition, installers can configure the module quickly during commissioning.

Plug-In Terminal Blocks

Removable plug-in terminal blocks accept 12–18 AWG wiring, making installation and servicing faster while reducing wiring errors.

Mounting & Design

The Silent Knight IDP-RELAY-6 is designed for installation inside the compatible IDP-ACB cabinet, which accommodates up to two relay modules. Furthermore, the compact circuit board includes mounting hardware and removable wiring terminals for efficient installation and future maintenance.

Its durable construction makes the module suitable for commercial facilities requiring dependable equipment control through the fire alarm system.
