General Information
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 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. See
Ordering Information.
Testing
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).
