The A50E-2 is an addressable relay module that provides a single-pole, volt-free, change-over contact output. It is engineered for direct installation inside the enclosure of the equipment it controls. By placing the interface adjacent to the target device, it eliminates the need for long auxiliary wiring runs from the main control panel, significantly lowering installation costs.

Fully approved to EN54-18 standards, the relay can be connected at any point along a two-core ZP data loop. It is primarily designed to safely manage building services during a fire event—either by activating emergency systems or shutting down high-risk utilities.

Key Applications

The module provides reliable control for a variety of critical building functions, including:

• HVAC Management: Tripping air conditioning plants and ventilation systems.

• Access Control: Activating door release and magnetic hold-open circuits.

• Emergency Shutdowns: Isolating high-risk fuel lines, such as gas or oil supply valves in boiler rooms.
