EP203 Automatic Extinguisher Panel



LPCB certified to EN 12094-1 (the European standard for Fixed Firefighting Systems - Components for Gas Extinguishing Systems) and EN54-2/4, the EP203 three zone automatic extinguisher panel epitomises quality, durability and reliability.

Specifically designed for use in areas housing expensive, dangerous or irreplaceable items of equipment, it features an intuitive 128 x 64 pixel display that gives clear and concise feedback to the user, installer and commissioning engineer. It has six monitored inputs (including hold & 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.

All of the panel's electronics - apart from its powerful 3A EN54-4 switch mode PSU - are 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 & abort buttons, line terminators and relay boards.

Stop! Hold! Abort!

The nature and cost of fire suppressing agents means many installers shy away from extingishant systems with one of their biggest concerns the accidental release of the suppressant in a false alarm situation. Have no fear, C-TEC's IP66 rated Hold and Abort Buttons can be used to delay (hold off) or cancel (abort) the extinguishant release sequence at any time depending on how they are configured. Job done!
