JOHNSON CONTROLS RDR2SA CONTROL MODULE S300-DIN-RDR2SA, 24-10239-472 #3

JOHNSON CONTROLS RDR2SA CONTROL MODULE S300-DIN-RDR2SA, 24-10239-472 #3

The Johnson Controls RDR2SA Control Module (Part #: 24-10239-472) is a versatile and reliable DIN-rail mounted interface device designed for fire alarm and life safety systems. This module provides a crucial link between your fire alarm control panel (FACP) and various building systems that require automated control during an emergency.

Core Function & Purpose:
The RDR2SA acts as a supervised relay module. It receives a command signal from the compatible fire alarm control panel and activates its onboard Form-C (SPDT) relay. This action can control external devices or circuits, enabling critical life safety functions such as shutting down HVAC fans (to prevent smoke spread), releasing magnetically locked doors, initiating elevator recall, or controlling other auxiliary equipment.

Key Features & Benefits:

• DIN-Rail Mounting: Designed for easy, organized installation within electrical cabinets, saving panel space and simplifying wiring.

• Supervised Operation: Continuously monitors its own health and the integrity of its connections to the control panel, ensuring reliability.

• Form-C Relay Contacts: Features a Single-Pole, Double-Throw (SPDT) relay rated at 2.0 Amps @ 30VDC. This provides a Normally Open (NO) and a Normally Closed (NC) contact for flexible circuit control.

• LED Indicators: Clear visual status indicators for Power, Activation, and Communication.

• Wide Compatibility: Designed for use with Johnson Controls, Silent Knight, and Gamewell-FCI fire alarm systems that support the S300 series protocol, including the popular 5207/5208 panels and 6000 series.

• Compact & Efficient: Its modular design allows for efficient use of space in control enclosures.

Primary Applications:

• HVAC Control / Fan Shutdown: Isolates smoke by shutting off air handling units.

• Door Release / Smoke Door Control: Releases electromagnetic locks on stairwell or corridor doors.

• Elevator Recall: Signals elevators to recall to a designated floor in a fire emergency.

• Auxiliary Control: Operating dampers, shutting down industrial processes, or activating other safety equipment.

• General Purpose Relay Control: For any application requiring a reliable, panel-controlled switch.
