Telefire ADR-812 Two-Channel Input Module

Maximize the flexibility of your fire alarm system with the Telefire ADR-812 two-channel input module. This interface unit enables the connection of conventional detectors and dry contacts to the Telefire intelligent analog addressable system. The module is an ideal solution for integrating existing conventional detectors or monitoring specific extinguishing system components (e.g., flow switches, valve monitors).

The ADR-812 provides two independent Initiating Device Circuits (IDCs) utilizing Class B (NFPA 72 Style C) wiring. The module occupies two consecutive addresses on the addressable loop, allowing the control panel to identify and manage each channel as a separate device. Inputs can be programmed to receive not only fire alarms but also technical and supervisory signals, making it universally applicable for various building monitoring tasks. The module requires 24V DC auxiliary power, which it continuously monitors, sending an immediate report to the panel in case of failure (e.g., blown fuse, voltage loss).

Key Features and Benefits:

• Two-Channel Design: Two independent input zones (IDC) in a single module, occupying two addresses on the loop.
• Conventional Device Interface: Allows connection of 2-wire conventional smoke and heat detectors, manual call points, or flow switches.
• Programmable Inputs: Inputs can be configured for Alarm, Fault, Supervisory, Reset, or other technical signal monitoring.
• Power Supply Monitoring: Continuous monitoring of the 24V DC auxiliary power; automatic fault reporting upon failure.
• Resettable Output: The module’s power output can be interrupted via a “Reset” command from the panel, resetting connected conventional detectors (which latch upon alarm).
• Comprehensive Supervision: Monitors input lines for open and short circuits, as well as power supply status.
• Power Requirements: Requires 24V DC auxiliary power (e.g., from TPS-34A power supply or the control panel).
