Description
POTTER OSYSU-1 Electric Supervisory Single Switch – DB-217-M
The OSYSU is used to monitor the open position of an OS& Y (outside screw and yoke) type gate valve. This device is available in two models; the OSYSU-1, containing one set of SPDT (Form C) contacts and the OSYSU-2, containing two sets of SPDT (Form C) contacts. These switches mount conveniently to most OS & Y valves ranging in size from 2″ to 12″ (50mm to 300mm). They will mount on some valves as small as 1/2″ (12,5mm). The cover is held in place by two tamper resistant screws that require a special tool to remove. The tool is furnished with each device and should be left with the building owner or responsible party. Replacement or additional cover screws and hex keys are available.
