EP203 Automatic Extinguisher Panel
The EP203 three zone automatic extinguisher panel has been specifically designed for use in areas housing expensive, dangerous or irreplaceable items of equipment.
Third-party approved by the LPCB to EN12094-1 (the European standard for Fixed Firefighting Systems – Components for Gas Extinguishing Systems) and EN54 parts 2 and 4, the EP203 panel represents a high standard of quality, durability and operational reliability.
The panel features an intuitive 128 × 64 pixel two-colour graphic display that provides clear operational feedback to users, installers and commissioning engineers. It includes six monitored inputs including hold and abort functions, a time-stamped event log, adjustable flooding times and multiple volt-free changeover relays for fire, local fire, first stage activation, second stage activation, extractor fan control and fault indication.
The EP203 is housed in a robust and elegantly styled enclosure. All electronics, apart from the powerful 3A EN54-4 switch-mode PSU, are mounted on a detachable metal bridge plate allowing easy installation and maintenance. A wide range of compatible accessories is also available including remote status units, hold-off and abort switches, line terminators and relay expansion boards.
