S P R I N K L E R S Y S T E M S M O N I T O R I N G Series State Detectors Available Parts Cover wrench Cover tamper switch kit Gasket kit Retard PCB kit Overview state retard assures precise accuracy Switch selections simplify settings two wire design connection to a local bell and or addressable systems with a wide range of pipe including 5 through 40 are equipped with a 4 gasket switches activate the alarm panel and local simultaneously retard assembly cover removed Sensor Accuflow series is a new line of solid state waterflow compatible with a wide range of pipe schedules including 2 schedule 5 detectors can be mounted in a vertical or horizontal position Construction The Accuflow series consists of a rugged enclosure for indoor outdoor use Like all System Sensor waterflow detectors Accuflow models oper across a wide temperature range from 32 to 120 0 to 49 Performance Accuflow detectors incorporate a solid state retard to ensure accurate timing Designed for use within conventional and addressable alarm systems Accuflow detectors include connections for both the panel or module as well as a local bell or notification device Alarm Immunity The solid state circuitry of the Accuflow series provides great timing accuracy over traditional mechanical retard designs This accuracy mini the risk of false alarms created by pressure surges or air trapped within sprinkler system Operation Accuflow detectors are designed to simplify installation Wired traditional waterflow detectors the Accuflow series does not require the installer run an additional third wire Two conduit openings permit easy attachment to the alarm system Specification waterflow detector with a solid state retard shall be an Accuflow Series model number manufactured by System and shall be installed on system piping as designated on the drawing and or as specified herein Detectors shall mount on any pipe span of the appropriate nominal size either on a vertical upflow or horizontal run at least 6 from any fittings which may water direction flow rate or pipe diameter or no closer than 24 from a valve or drain Detectors shall be compatible with sched 5 through 40 for 2 diameter pipe schedule 7 through 40 for 21 2 6 diameter pipe and schedule 10 through 40 for 8 diameter pipe shall have a sensitivity in the range of 4 to 10 gallons per minute and a static pressure rating of 450 psi for 2 8 diameter The detector shall respond to water flow in the specified direction after a preset time delay The delay mechanism shall be a solid unit which is field adjustable via a dipswitch The detector actuation mechanism shall include a polyethylene vane inserted through hole in the pipe and connected by a mechanical linkage to the delay mechanism Outputs shall consist of one SPDT switch Form C con and one SPST switch normally open contact for wiring to an alarm panel or addressable control module and local bell and or noti device Two conduit entrances one knockout type for standard fittings of commonly used electrical conduit shall be provided on detectors A grounding provision shall be provided Unless noted enclosures shall be NEMA 4 listed by Underwriters Laboratories

fire alarm control panel When compatibility of these devices the operating voltage of the control panel must between 8.5 and 35 volts In the standby mode Accuflow and Accuflow Low Flow detector as a shot across the initiating zone For two conventional fire alarm control panels not than 5 waterflow detectors may be connected a single initiating zone The maximum retard time of the waterflow detector plus the initi zone shall not exceed 90 seconds two wire addressable control panels the of waterflow detectors connected to the signaling line circuit shall be limited by the current capacity
