Telefire ADR-823 Three-Channel Input/Output Module

Enhance the flexibility of your Telefire analog addressable fire alarm system with the versatile ADR-823 input/output module. This specialized unit combines three independent channels into a single compact housing, offering an ideal solution for simultaneous supervisory, alarm, and automatic extinguishing control tasks. The module connects directly to the addressable loop, providing an intelligent interface between the control panel and field devices (e.g., sounders, flow switches, extinguishing systems).

The ADR-823 features two output circuits (NAC) and one input circuit (IDC), whose operation and logic can be set via jumpers in four different configurations. This modularity allows you to implement complex controls with a single device that would previously have required multiple separate modules. It is particularly suitable for controlling extinguishing systems, where sounder activation, extinguishing release, and pressure switch monitoring can be managed from one location.

Key Features and Benefits:

• 3-in-1 Functionality: Two supervised output (NAC-A, NAC-B) and one input (IDC) channels in a single module.
• Flexible Configuration: 4 selectable operation modes (jumper configurable) defining channel addressing and logic.
• NAC-A Output: Reverse polarity output that also activates an additional dry relay contact (e.g., for sirens).
• NAC-B Output: Level-activated (voltage output) operation, ideal for triggering extinguishants or strobes.
• Input Channel (IDC): Supervised input suitable for connecting flow switches, manual call points, or supervisory pressure switches.
• Addressability: Occupies 1 to 3 consecutive addresses on the loop, depending on the selected configuration.
• Reliability: Continuous monitoring of power supply and loop status; immediate reporting to the panel in case of fault (open circuit, short circuit, power loss).
