Sentech SSG-MCD Fire Suppression Monitor
(Sentech SSG-MCD Suppression Monitor System Guard (Replaces the SSG Supression System Guard Monitors).
Sentech SSG-MCD Fire Suppression Monitor, infrared monitors are advanced multi-point refrigerant detection systems. It is designed for highly reliable performance with the flexibility to satisfy a wide range of continuous monitoring applications. Sentech SSG-MCD Fire Suppression Monitor offers a choice of 1, 4, 8, or 16 zone detection point capability from a single field-programmable self-contained metal enclosure. Sentech SSG-MCD Fire Suppression Monitor utilizes NDIR (Non-dispersive infrared) and pyro-electric (absorptive sensing) technology. Each zone (detection location) is capable of monitoring and responding to any one of 22 refrigerants from a standard library via keypad entry. Sentech SSG-MCD Fire Suppression Monitor is very expandable, offering users the flexibility to change configurations or applications at a later date.

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