Conventional Reflective Beam Detector 5-50m – MBD50R

Cooper MBD50R Conventional Reflective Beam Detector – 50m Range

The Menvier range of zone powered reflective beam detectors are specifically designed to be compatible with the full range of conventional Menvier control panels.

Two versions are available, the MBD50R with a range of up to 50 metres, and the MBD100R with a range of 50 – 100 metres.

Both of these units are extremely simple to install, they require no separate power supply, operate on a reflective principle and have a simple set up mode to enable easy and quick alignment during installation. Beam detectors are designed to replace individual point detectors in large open areas such as warehouses.

Fire and fault conditions are signalled to panel using standard zone wiring so no additional interconnection is required.

In normal operation only one beam detector may be connected per zone, however special versions are available to work with external power supply if multiple beam detectors are required to be connected to a single zone

Reflective beam technology: cost-effective smoke detection for large, open areas

The detector features two parts: a transmitter-receiver and reflector. The transmitter-receiver directs a continuous infra-red beam towards the reflector which utilising a prism then sends back the beam to the transmitter-receiver which in turn registers the strength of the beam.

A fire or fault is signalled when the continuous beam is interfered between the two parts by smoke; reducing the strength of the beam. The transmitter-receiver is preset to indicate a fire or fault when the beam’s strength is below a certain value.

Detectors that speak to the panel with ease of connection

The optical beam detector for use with Eaton conventional fire systems, operate using standard loop wiring. Thanks to their loop interconnectivity, fire and fault conditions are signalled directly to the conventional control panel, removing the need for any additional connections. They also have a simple set up mode enabling easy and quick alignment during installation.

Built in quick test

To help you with testing, each reflective beam detector is supplied with a test filter to simulate required smoke obscuration levels. This will help you to quickly confirm that any reflective beam detectors, that you install, are operating correctly.
