An extensive range of interfaces are available to support the Eaton range of control panels, providing solutions for most design requirements.
The shop monitor unit (MSU840) is designed to enable small units with conventional fire detection to be fully integrated with a main intelligent addressable fire system.
This unit is ideal for applications such as connecting individual shop units into a main shopping centre system.
An external power supply is required to drive the 2 conventional sounder circuits. This power supply must be regulated for fire and current limited.

Over the course of many years shopping centres and their individual retail units evolve as businesses come and go.
For fire alarm systems this can represent a significant challenge as the use of space changes, the system must also change to match new demands.
Interfaces allow for a variety of installations to be simplified without the use of specialist or customised equipment, making it simple to expand fire alarm systems with existing wiring.
The shop monitor unit empowers building owners to maximise the functionality and flexibility of retail units with the ability to connect individual units to a larger central system. The intelligent device can connect an unlimited number of call points as well as up to 20 detectors. Call points can also be connected with detectors on the detector zone if preferred.
Designed to ease the process of expanding your addressable system, the monitor provides flexibility to be used in airports, office blocks and even sports stadiums.
