The SSP 1230 systems use a proprietary continuous linear tube that reliably detects fire and actuates release of 3M™  Novec™ extinguishing agent for flexible, space efficient and cost effective suppression. Install directly inside electrical cabinets, CNC machines, or fume cabinets. Flexible sensor tubing is easily installed on cabinet or enclosure walls or roofs. The tubing is pressurized with dry nitrogen to 240 psi, making the tubing more reactive to heat. If a flame-up occurs, the fire's heat causes the pressurized sensor tube to burst at the hottest spot (approximately 240° F.) The sudden tube depressurization actuates the special pressure differential valve and instantly floods the entire cabinet with Novec™ extinguishing agent. The fire is quickly suppressed just moments after it began...minimizing damage and downtime.
