60174 FAX 630 377 6495 Switch 9B Knockout plug removal 10 Electronic Retard Timing Chart sec 1 sec 2 sec 3 sec 1 Table 1 for hole size Only use the above timer settings must not exceed 90 seconds refer to insert for the Limitations of Fire Alarm Systems Limitations of Waterflow Alarm Devices Waterflow detectors may not work or operate properly if sprinkler pip being monitored is plugged with pipe scale mud stones or other material Sprinkler systems should be checked regularly for blocking material following the instructions in Chapter 5 of Standard 13A Alarms generated by the activation of waterflow detectors may not be by a central station if telephone or other communication lines the detector are out of service disabled or open Vane type waterflow detectors have a normal service life of 10 15 Hard water systems however may reduce waterflow detector life to 4 or 5 years Waterflow detectors are not a substitute for insurance Building owners always insure property and lives being protected by sprinkler valves controlling the water supply to a sprinkler system are closed waterflow detectors will not work All valves controlling a water supply should be sealed or locked in the normally open The normally open position should be monitored by a sprin supervisory switch Limited Warranty Sensor warrants its enclosed waterflow detector to be free from de in materials and workmanship under normal use and service for a of three years from date of manufacture System Sensor makes no express warranty for this waterflow detector No agent representa dealer or employee of the Company has the authority to increase or the obligations or limitations of this Warranty The Company obli of this Warranty shall be limited to the repair or replacement of any of the waterflow detector which is found to be defective in materials workmanship under normal use and service during the three year pe commencing with the date of manufacture After phoning System toll free number 800 SENSOR2 736 7672 for a Return Authori number send defective units postage prepaid to System Sensor Department RA 3825 Ohio Avenue St Charles IL Please include a note describing the malfunction and suspected of failure The Company shall not be obligated to repair or replace which are found to be defective because of damage unreasonable modifications or alterations occurring after the date of manufacture no case shall the Company be liable for any consequential or incidental for breach of this or any other Warranty expressed or implied even if the loss or damage is caused by the Company negli or fault Some states do not allow the exclusion or limitation of inci or consequential damages so the above limitation or exclusion may apply to you This Warranty gives you specific legal rights and you also have other rights which vary from state to state Ratings Threshold Bandwidth Flow Rate Pressure Rating Installed Temperature Range Pipe Weight Rating Range Requirements A 125 VAC 2 A

Carefully And Save instruction manual contains important information about the instal and operation of waterflow detectors Purchasers who install detectors for use by others must leave this manual or a copy of with the user all instructions carefully before beginning Follow only those instruc that apply to the model you are installing vane type waterflow detectors in wet pipe systems only Do NOT use in dry pipe deluge or preaction systems The sudden inrush of wa in such systems may break the vane or damage the mechanism not use in potentially explosive atmospheres Do not allow unused to remain exposed Of Operation waterflow detectors mount to water filled pipes in sprinkler sys Waterflow in the pipe deflects a vane which produces a switched after a specified delay All waterflow detectors have a con delay mechanism Delays do NOT accumulate they reset if the of water stops before the entire delay has elapsed All switches actu when the water flow rate is 10 gallons per minute or greater but will actuate if the flow rate is less than 4 gallons per minute This System installation manual covers the following waterflow detectors for alarm applications Models Diameter Schedules through 40 through 40 through 40 through 40 through 40 through 40 through 40 through 40 NOT use any of the AFD models on copper pipe The clamping forces the mounting bolts may collapse the pipe sufficiently to prevent the de from functioning properly NOT install steel or iron pipe sections in copper piping for mounting a detector Incompatibility between the dissimilar metals causes corrosion Guidelines installing any waterflow alarm device be thoroughly familiar with 72 13 25 applicable NFPA standards local codes and the requirements of the having jurisdiction Fire Alarm Code of Sprinkler Systems Testing and Maintenance of Sprinkler Systems methods other than those listed in this installation may prevent the device from reporting the flow of water the event the associated sprinkler system is activated by a System Sensor is not responsible for devices that have been installed tested or maintained Mount the detector where there is adequate clearance for installation removal and a clear view of it for inspections See Figure 1 for dimensions Locate detector 6 to 7 ft above the floor to protect from potential damage On horizontal runs position the detector on the top or side of the pipe not mount it upside down because condensation may collect in the and impair the operation of the detector For vertical flow ap mount the detector on pipe through which water flows up Otherwise the unit may not operate properly Mount the detector at least 6 inches from a fitting that changes the di of water flow and no less than 24 inches from a valve or drain Be sure the direction of flow arrow matches the direction of flow the pipe Instructions Drain the pipe Cut a hole at the desired location Center the hole in the pipe as in Figure 2 and be sure the hole is perpendicular to the center the pipe Before drilling use a punch or scribe to mark the drill site prevent the bit from slipping If the hole is off center the vane will against the inside wall of the pipe Use a drill or hole saw to cut a of the proper diameter See Table 1 for hole size drilling the hole with a hole saw make certain that the center of the does not remain in the pipe Remove burrs and sharp edges from the hole Clean and remove scale and foreign matter from the inside of the pipe for one di on each side of the hole to ensure free movement of the Clean the outside of the pipe to remove dirt metal chips cutting lubricant System Sensor Manuals Online Seat the O ring or gasket against the saddle and mount the detector di to the pipe Carefully roll the vane opposite the direction of flow insert it through the hole Seat the saddle firmly against the pipe that the locating boss goes into the hole the U bolt tightening the nuts alternately to ensure a uniform See Table 2 for torque values Remove the metal cover with the tamper proof wrench provided Move actuator lever back and forth to check for binding If the vane remove the detector and correct the cause before proceeding
