Esento Marine 2-4 Zone MED Approved Fire Alarm Control Panels

The Esento Marine 2-4 is a Marine Approved 2 or 4 zone conventional fire alarm control panel. Even as an entry level panel, the Esento Marine 2-4 encompasses all of our usual quality, reliability and ease of use attributes to provide a panel that meets a variety of needs.


Product Overview

Quality, reliability, ease of use and feature rich are attributes that are consistent across the entire range of Haes fire alarm control panels. As an entry level panel, the Esento Marine 2-4 zone encompasses all of these attributes to provide a panel that meets a variety of needs.

For the fire alarm engineer the Esento Marine 2-4 has been designed to minimise labour costs. There is ample room for wiring, changing batteries and clear indication. Activation is via key switch or access code, which means you should always be able to work on the panel and the one man walk tests will help reduce the cost of maintaining the fire alarm system.

Simplicity was one of the most important aspects when considering the end user of a fire alarm panel. The colour coded buttons and the 3 step silence functionality gives non-technical people the confidence to correctly manage their fire alarm system.

The Esento Marine 2-4 provides a number of important and useful features including a false alarm management mode, muster alarm and programmable output delays.

Two or four fire zone circuits are provided plus two monitored sounder circuits. Fire & Fault VFCO relays, Fire & Fault switched negative outputs, class change and an alert input are also included. The battery compartment also includes a secure battery clamp.

Esento Marine panels are approved by the BRE which is a Notified Body authorised by the MCA to Modules B & D, Lloyds Register and the American Bureau of Shipping
