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 EN 12094-1 (the European standard for Fixed Firefighting Systems - Components for Gas Extinguishing Systems) and EN54 parts 2 and 4, the panel epitomises quality, durability and reliability.

Featuring an intuitive 128 x 64 pixel two-colour graphic display that gives clear and concise feedback to the user, installer and commissioning engineer, the panel also includes six monitored inputs (including hold and abort), a time stamped log, adjustable flood times and volt-free changeover relays for fire, local fire, 1st stage active, 2nd stage active, extractor fan and fault.

The panel is supplied in an elegantly styled, durable enclosure with all of its electronics - apart from its powerful 3A EN54-4 switch mode PSU - mounted on a detachable metal bridge plate for ease of installation. A wide range of ancillaries are also available including remote status units, hold-off and abort buttons, line terminators and output expansion relay boards.
