SSG-MCD Multiple Zone Fire Suppression Agent Loss Monitor

The SSG Monitors are advanced early warning loss detection and prevention monitoring systems designed specifically for fire suppression systems.

The SSG Monitors are advanced early warning loss detection and prevention monitoring systems designed specifically for fire suppression systems.

SenTech's SSG models are cost effective, self-contained monitors of halogenated gases that activate an alarm at a preset concentration that is programmed by the user. The Series includes single, four and eight zone models. SenTech's unique built in leak wait period minimizes nuisance false alarms.

SenTech SSG monitors provide 24/7 protection.

The SSG systems are based on an advanced infrared technology that can detect multiple gas types at concentration levels as low as one part per million (PPM).

The SSG Monitoring System reduces the risk of accidental suppression agent discharges by continuously sampling the air for halogenated compounds. In critical environments, Halon and FM-200 discharges occur more frequently by accident than by fire. The primary cause of agent discharges is refrigerant leaks from supporting air conditioning systems. By installing a SenTech SSG Monitoring System, this costly scenario can be avoided. One SSG Monitoring System can sample up to 16 zones and can be field programmed for various refrigerants and types of agents providing the earliest warning leak detection available today.

The SSG Monitoring System can interface with existing suppression system panels to automatically abort a Halon discharge due to a refrigerant leak, thus preventing the costly replacement of agents, and minimizing risks of downtime associated with a Halon system discharge.

SenTech's SSG Monitoring System is a cost effective solution for preventing critical downtime, avoiding business disruptions and suppressing system equipment failures.
