Riser Mount Corrosion Monitoring Station

The Model PCMS-RM, is a Corrosion Monitoring Station-Riser Mount consisting of a coupon rack that is installed on fire sprinkler riser to monitor corrosion in a fire sprinkler system. The PCMS-RM is designed to simulate conditions within the fire sprinkler system. The coupon rack can be isolated from the fire sprinkler riser and easily accessed for servicing and monitoring of testspecimens(corrosion coupons) without interruption to fire protection. Test material strip specimens (corrosion coupons) are installed into the coupon rack using coupon holders. The PCMS-RM can be used on wet or dry pipe systems.

The optional PCMPK-1 contains a corrosion monitoring probe and pressure switch that provides notification to the fire/sprinkler administrator when there may be an excessive amount of corrosion taking place in the sprinkler piping.The corrosion monitoring probe has a precision thin wall thickness which will eventually corrode through, allowing the system pressure to enter into the probe and actuate the pressure switch. When the pressure switch is wired to the building fire alarm panel, a trouble or supervisory signal is generated notifying the fire/sprinkler administrator. This is the notification to remove the test coupons that were installed at the same time as the probe, for analysis on the condition of the sprinkler piping. The corrosion monitoring probe is a single use device and must be replaced upon the installation of new test coupons.

The CPRTK2-Coupon/Probe Replacement Test Kit contains the necessary components to remove, replace, and forward for analysis, test coupons, and water sample from a PCMS-RM.
