WF SERIES SYSTEM SENSOR WATER FLOW AND SUPERVISORY SWITCHES DESCRIPTION WFDT, WFDTNR T-Tap Waterflow Detectors The System Sensor WFD (with retard) and WFDTNR (less retard) waterflow detectors are housed in durable, tamper resistant enclosures and are designed for primary signaling in residential and branch line signaling in larger systems. The units contain a polyethylene vane which is inserted through the tee fitting and connected by a mechanical linkage to the trip mechanism. The detectors have a sensitivity in the range of 4 to 30 gpm and a static pressure rating of 250 psi. The units fit in any tee that has a 1" NPT branch including: 1", 1 1/4", or 1 1/2" threaded ferrous or brass tee; 1-2" copper sweat tees; 1" CPVC tee; or 1 1/2" polybutylene tee. The detectors come with nine different flexible paddles that fit the specified tees. The detectors are UL Listed for indoor/outdoor use. Dual SPDT switches accommodate up to 12 AWG wire. WFD Series Vane Type Waterflow Detectors The System Sensor WFD Series waterflow detectors are equipped with a computer designed paddle or vane which fits Schedule 20 through Schedule 40 steel pipe sizes 2" through 8". They are equipped with a pneumatic retard, can be mounted in a vertical or horizontal position and are suitable for UL Listed outdoor wet pipe sprinkler installations. The detectors have a sensitivity in the range of 4 to 30 gpm and a static pressure rating of 250 psi. Housed in a durable, enclosure with red epoxy painted metal cover secured by self-guiding security screws, the detectors are resistant to tampering. The WFD Series is UL Listed for indoor/outdoor use. Dual SPDT switches accommodate up to 12 AWG wire. EPS10-1, EPS10-2 Alarm Pressure Switches The System Sensor EPS10-1 and EPS10-2 Alarm Pressure Switches are designed for use in wet, dry, deluge, and preaction automatic sprinkler systems to indicate a discharge from a sprinkler. The switches feature field adjustable pressure sensitivity to provide an alarm response between 4 and 20 psi. It is factory set to respond at 4-8 psi on rising pressure. The pressure adjustment wheel requires no special tools and does not affect switch synchronization on the EPS10-2. The EPS10 switches are UL Listed for weatherproof use with a NEMA 4 rating. A single SPDT switch on the EPS10-1 and dual SPDT switches on the EPS10-2 accommodate up to 12 AWG wire. Specifications are provided for information only and are believed to be accurate.

The switch is designed to mount easily on most OS&Y valves ranging in size from 1" to 12". The OSY2, without its gate valve bracket, can be used to monitor side-bracket style pressure reducing valves. Its three-position switch gives vandal and valve closed signals. The OSY2 is UL Listed for indoor/outdoor use. Dual SPDT switches accommodate up to 12 AWG wire. PIBV2 Supervisory Switch The System Sensor PIBV2 Supervisory Switch monitors the open position of fire sprinkler control valves of the post indicator, butterfly, or other valves. The PIBV2 is designed to operate when the valve position is altered from an open state. The switch can be used for butterfly valves, post indicator valves, wall post mount (with restrictions) recessed wall post valves and many types of pressure reducing valves. The PIBV2 is UL Listed for indoor/outdoor use. Dual SPDT switches accommodate up to 12 AWG wire. EPS40-1 Low Pressure Supervisory Switch The System Sensor EPS40-1 Low Pressure Supervisory Switch is designed to detect a 10 psi decrease from normal system pressure in automatic fire protection systems. It is typically used to supervise system air pressure in dry pipe systems or pressure tanks and water pressure supplies of automatic water control valves. It features field adjustable pressure sensitivity between 10 and 100 psi. It is factory set to be used in a nominal 40 psi system with a switch transfer occurring at 30 psi. The pressure adjustment wheel requires no special tools and can be used to adjust the point at which the low switch activates. The EPS40-1 switch is UL Listed for weatherproof use with a NEMA 4 rating. The SPDT switch accommodates up to 12 AWG wire. EPS120-2 High/Low Pressure Supervisory Switch The System Sensor EPS120-2 High/Low Pressure Supervisory Switch is designed to detect a 10 psi decrease or increase from normal system pressure in automatic fire protection systems. It is typically used to supervise system air pressure in pipes or pressure tanks and water or air pressure supplies of automatic water control valves. It features field adjustable pressure sensitivity between 10 and 200 psi. It is factory set to be used in a nominal 115 psi system with a switch transfer occurring before 105 psi and a second transfer occurring before 125 psi. The pressure adjustment wheel requires no special tools and can be used to adjust the nominal value of the “window” at which the low and high switches activate. The EPS120-2 switch is UL Listed for weatherproof use with a NEMA 4 rating. Dual SPDT switches accommodate up to 12 AWG wire. 2 of 3 9020-0446 SPECIFICATIONS WFD, WFDT, WFDTH, OSY2, PIBV2 Series: Operating temperature range: 32o F to 120o F (0o C to 49o C) Contact ratings: 10 A @ 125/250 VA, 2.5 A @ 24 VDC Overall dimensions: WFDT 4.5" H x 3.75" W x 6.7" L (11.4 cm x 9.5 cm x 17 cm) WFDTNR 3.75" H x 3.25" W x 4.25" L (9.5 cm x 8.2 cm x 10.8 cm ) PIBV2 ` 4.25" H x 3.5" W x 3.25" D (10.8 cm x 8.9 cm x 8.2 cm) OSY2 5.25" H x 3.5" W x 3.25" D (14.6 cm x 8.9 cm x 8.2 cm) WFD (switch body) 3" H x 3.75" W x 6.7" L (8 cm x 9.5 cm x 17 cm) Over all width: WFD20, 25 4.6" (11.7 cm) WFD30 5.2" (13.2 cm) WFD35 5.7 (14.5 cm) WFD40 6.8" (17.3 cm) WFD50 7.8" (19.8 cm) WFD60 9.0" (22.9 cm) WFD80 10.8" (27.4 cm) EPS Series: Contact ratings: Operating temperature range: Dimensions: 10.0 A, 1/2 HP @ 125/250 VAC, 2.5 A @ 6/12/24 VDC -40o F to 160o F (-40o C to 71o C) 5.12" H x 3.325" W x 4.250" L (13.0 cm x 8.4 cm x 10.8 cm) PSP-1 Plug-in type switch: Operating temperature range: Dimensions: -4o F to 149o F (-20o C to 65o C) 4.73" L x 2.94" W x 2.21" D (12 cm x 7.5 cm x 5.6 cm) ORDERING INFORMATION Part No. Model Description 117-90000 117-90001 117-90003 117-90004 117-90005 117-90006 117-90007 117-90008 117-90009 117-90010 117-90011 117-90012 117-90013 117-90014 117-90015 117-90016 117-90017 117-90018 117-90019 WFDT WFDTNR WFD20 WFD25 WFD30 WFD35 WFD40 WFD50 WFD60 WFD80 OSY2 PIBV2 PSP1 EPS10-1 EPS10-2 EPS40-1 EPS40-2 EPS120-1 EPS120-2 Waterflow Switch, Vane Type, w/retard, for 1, 1 1/4, 1/12" pipe Waterflow Switch, Vane Type, less retard, for 1, 1/4, 1 1/2" pipe Waterflow Switch, Vane Type, w/retard, DPDT, for 2" pipe Waterflow Switch, Vane Type, w/retard, DPDT, for 2 1/2" pipe Waterflow Switch, Vane Type, w/retard, DPDT, for 3" pipe Waterflow Switch, Vane Type, w/retard, DPDT, for 3 1/2" pipe Waterflow Switch, Vane Type, w/retard, DPDT, for 4" pipe Waterflow Switch, Vane Type, w/retard, DPDT, for 5" pipe Waterflow Switch, Vane Type, w/retard, DPDT, for 6" pipe Waterflow Switch, Vane Type, w/retard, DPDT, for 8" pipe Supervisory Switch, Outside Screw and Yoke Supervisory Switch, Post Indicator/Butterfly valve Supervisory Switch, Plug-in (wire leads) Waterflow Pressure Switch, SPDT, (4-20 psi) Waterflow Pressure Switch, DPDT, (4-20 psi) Waterflow Pressure Switch, SPDT, (10-100 psi) Waterflow Pressure Switch, DPDT, (10-100 psi) Waterflow Pressure Switch, SPDT, (10-200 psi) Waterflow Pressure Switch, DPDT, (10-200 psi) 9020-0446 3 of 3
