Description
Ctec 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 epitomizes 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 is also available including remote status units, hold-off & abort buttons, line terminators, and relay boards.
