General Information
The OSYSU is used to monitor the open position of an OS&Y (outside screw and yoke) type gate valve. The OSYSU-1, contains one set 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 ½" (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. See Ordering Information.

Optional Cover Tamper Switch
A field installable cover tamper switch is available as an option which may be used to indicate removal of the cover.

The OSYSU and its associated protective monitoring system should be inspected and tested in accordance with applicable NFPA codes and standards and/or the authority having jurisdiction (manufacturer recommends quarterly or more frequently).

Limited Support

In most cases, the installation or expansion of a commercial fire alarm system is determined by code requirements. There is federal, state, and local codes that come into play, specifying who must install fire alarm equipment, what type of equipment must be installed, where and how it must be installed. Failing to comply fully with any of these codes can result in denial of occupancy permits, fines, legal and financial liability.

Sorry we do not offer technical support for these products because of local codes that come into play specifying who must install fire alarm equipment and where and how it must be installed. To read more, visit the National Fire Alarm and Signaling Code website.
