Designed for use in wet, dry, deluge, and preaction automatic sprinkler systems to indicate a discharge from a sprinkler.
Used to monitor the open position of an OS&Y (outside screw and yoke) type gate valve. This device contains 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.
They have low power consumption and high decibel ratings. The unit mounts on a standard 4" (101mm) square electrical box for indoor use or on a model BBK-1 weatherproof backbox or BBX-1 deep weatherproof backbox for outdoor applications.
The WFD Series waterflow detectors provide a mechanical time delay that is adjusted via an adjustment wheel. This retard mechanism is field replaceable, as is the terminal block. System Sensor also offers several specialty waterflow detectors for unique applications. The WFD-EXP line of explosion-proof waterflow detectors is intended for use in hazardous locations where volatile vapors or particulates may be present.
Is a vane type waterflow switch for use on wet sprinkler systems that use 1" (25mm), 1-1/4" (32mm), 1-1/2" (38mm) or 2" (50mm) pipe size. The unit may also be used as a sectional waterflow detector on large systems. The unit contains two single pole double throw snap action switches and an adjustable, instantly recycling pneumatic retard. The switches are actuated when a flow of 10 gallons per minute (38 LPM) or more occurs downstream of the device. The flow condition must exist for a period of time necessary to overcome the selected retard period.
