Division of Pittway Waterflow Detectors with Solid State Retard Accuflow AND MAINTENANCE INSTRUCTIONS 2 Assembly diagram tlilSJIT Voltage Electrocution Hazard Do not handle live AC wiring or on a device to which AC power is applied Doing so may result in or death sure the direction of flow arrow points in the right direction a waterflow condition will go unreported See Figure 2 the sprinkler system with water and check for leaks around the or AFDTH If there is a leak check to see that the fittings are If leak persists drain the system and remove the detector removal instructions under Maintenance Check for damaged or cracked fitting Reinstall the detector and check again leaks Do not proceed until all leaks have been stopped All models have two wires and two sets of terminals Wires W1 W2 designated on PCB These wires are to a latching normally open as in No Flow relay con They are isolated from all electronics They will close and a short when water flows and the retard time elapses They remain shorted until waterflow stops Once waterflow stops contacts will re open Terminals T2 designated on PCB This is a two screw block The Accuflow gets its power from these termi These terminals must have voltage present from the FACP or suitable source of power before anything will work If no is present the Accuflow will not provide proper alarm sig These terminals will accept power in any polarity as well as power Relay Terminals T1 designated on PCB This is a THREE terminal block These terminals are connected to a latching C relay In no flow conditions COM is connected to A flow is detected COM will disconnect from A and connect B This relay will latch in that state and reset after water stops Adjust Dip Switch to desired time delay See Figure 11 For Dip location see Figure 2 When connected to a listed sprinkler fire alarm control panel initiating circuit must be nonsilenceable A ground screw is provided with all waterflow detectors When is required clamp wire with screw in hole located conduit entrance holes See Figure 9 page 4 If a second conduit entry is required remove the knockout plug a flat blade screwdriver as shown on Figure 10 page 4 sharply with a hammer to pierce the wall of the knockout Move to an adjacent wall section and repeat until the plug out Make sure that the waterflow detector is supported during this operation to avoid injury Power terminals must be connected to FACP or other initiating circuit Locate the detector 6 to 7 feet above the floor to protect from damage On horizontal runs position the detector on top of the pipe or the side of it Do not mount it upside down because conden may collect in the housing and impair the operation of detector For vertical flow applications mount detector on where upflow conditions exist Failure to do so may pre unit from operating properly Mount detector at least 6 inches from a fitting which changes direction of the water flow or no closer than 24 inches from valve or drain BE SURE DIRECTION OF FLOW ARROW MATCHES ACTUAL OF FLOW IN THE PIPE Instructions The AFDT and AFDTH waterflow detectors are designed to fit the appropriate tee fitting of tee perpendicular to flow of water must have a 1 thread Do not use a reducer to achieve the correct size Failure to follow this instruction will result in of the detector to report a waterflow condition AFDT and AFDTH units are shipped without paddles mounted the actuator Select the correct size paddle for the type of tee used Align hole on stem of paddle with hole on actuator Fasten together using a 4 40 x 1 4 fillister head screw in bag assembly See Figure 2 Use only the screw pro with the unit Drive screw head through hole in paddle it seats to actuator lever surface No washer is required paddle replacement refer to Maintenance section Carefully roll the vane opposite the direction of flow and insert tee Thread detector onto tee fitting and tighten with Use of thread sealant or tape is recommended Use gage located at end of paddle tree to ensure proper of detector on tee fitting See Figure 1 Height gage must between top of tee fitting and under side of hex tee adapter gap between gage and tee adapter is acceptable When cor installed the detector must face in the proper direction of and be aligned with the pipe Remove the metal cover Move the actuator lever back and forth check for binding If the vane binds remove the detector and the problem before proce
