Switch contacts COM and B-NO are closed when water is flowing and open when it is not.

System sensor water flow switch wiring diagram. The Water Flow Switch Option WFS is a piston activated in-line flow switch which requires filtering of the cooling system water to insure proper operation and long product life. Be sure the direction-of-flow arrow points in the right direction otherwise a Mount detector at least 6 inches from a fitting which changes the direc-tion of the water flow or no closer than 24 inches from a valve or drain. Water flow switch wiring diagram What is a Wiring Diagram.

With a hacksaw cut out a section of the PVC part of the water pipe that leads to your device. Dual switches permit applications to be combined on a single detector. All models have two SPDT switches.

Do not loop wires. FS-RT Delay mechanism and switch assembly CTS Tamper-proof switch kit WFDW Tamper-proof wrench for cover Engineering Specifi cations Model shall be WFDNFS or WFDNFT as manufactured by System Sensor. Water ow detectors shall be installed on a 1 1 1.

Switch to prevent unauthorized entry. Dual switches permit applications to be combined on a single detector. A wiring diagram is an easy visual representation with the physical connections and physical layout of an electrical system.

When water is flowing. Interconnecting wire courses could be shown approximately where particular receptacles or fixtures need to get on an usual circuit. Fit the switch into the space with the Water In end towards the device you want to wire.

Connect the switches as shown in Figure 7 depending on the application. Turn off the water. Water flow switch wiring diagram Architectural electrical wiring representations show the approximate areas and interconnections of receptacles lights and permanent electrical services in a structure.

The Potter VSR series is the industry standard for flow switches for fire sprinkler systems and is compatible with the widest range of pipe schedules 5 through 40 in the industry as well as all. BEFORE INSTALLING THE WATER FLOW SWITCH REMOVE ALL POWER TO THE CONTROL. A two-wire single-pole single-throw float switchThe rising action of the float can either close ie turn on a Normally Open circuit or it can open turn off a Normally Closed circuitInstallation scenarios might include a Normally Open float switch turning on a pump to empty a tank Control Schematic 2 or a Normally Closed.

Charles IL 60174 Phone. The new WFDN Series waterflow detectors from System Sensor consists of a rugged NEMA 4-rated enclosure that is more damage resistant than previous metal designs. ELECTRICAL CONNECTION The switch assembly has three wire connections.

When connected to a listed fire sprinklerfire alarm control panel the initiating circuit must be unable to be silenced. Models available for pipe sizes 2 through 10.

BB COMC OMCOMC Typical Fire Alarm Control Panel Connection B COM Typical Local Bell Connection Break wire as shown for. Place it as level as. Explosion Proof Vane Type Waterflow Switch.

All models have two SPDT switches. When water is flowing. A wiring diagram is a simplified traditional pictorial representation of an electrical circuit.

It is UL Listed and FM Approved for use on steel pipe. They are also approved for installation on the widest range of pipe schedules sizes 2 in. Turn off the fuse to cut the electricity going to the device to which you want to wire the water flow switch.

Quarterly flow switch tests are mandated by NFPA 25. System Sensors Zonecheck ow switch tester is an automatic method for performing quarterly ow switch tests per NFPA 25. May 14 2018 by headcontrolsystem.

There is a large barrier between switches and raised textured lettering make it easy to read. COM terminals are on a different elevation. Break wire as shown for supervision of connection.

Lets start with the most basic float switch. The waterflow detector is designed for both indoor and outdoor use with the widest avail able temperature range from 32F to 150F. Do notallow stripped wire leads to extend beyond switch housing.

It reveals the components of the circuit as simplified shapes and also the power and also signal links between the devices. Refer to the instructions that come with the switch to cut out the right size section. The Potter VSR is a vane type waterflow switch with non-corrosive insert for use on wet sprinkler systems.

Power 24vdc or 120vdc initiating loop ul-listed compatible control panel contact ratings 125250 vac 24 vdc 10 amps 2. When connected to a listed sprinklerfire alarm control panel the initiat-ing circuit must be nonsilenceable. Zonecheck simplifies testing by re-circulating the water within the pipe around the flow switch to simulate the flow of one sprinkler head in operation.

Top View Switch 1 CO M CO M AB BA Switch 2 NOTEC ommon and B connections will close when vane is deflected ie when water is flowing. Red - Normally Open No Flow Orange - Normally Closed Flow. Connect the switches as shown in Figure 4 depending on the application.

BE SURE DIRECTION-OF-FLOW ARROW MATCHES ACTUAL DIREC-TION OF FLOW IN THE PIPE. August 9 2018. Inside two sets of SPDT Form-C synchronized switches are enclosed in a durable ter-minal block with a new layout designed to make wiring easy with wire ready terminals.

Dual switches permit applications to be combined on a single detector. It is recommended that a 50 micron filter be used to protect the internal actuator of the switch. Assortment of water flow switch wiring diagram.

Switch contacts COM and B-NO are closed when water is flowing and open when it is not.
