1 WFDE Series Waterflow Detector The System Sensor WFDE series is compatible with pipe diameters ranging from 50mm through 200mm and can be mounted in a vertical or horizontal position. Features Compliant with Construction Products Directive EC Certificate Number 0786 CPD WFD30-2E models install in 50.8mm (2 ) hole sizes IP54-rated enclosure Sealed retard mechanism assures that the retard is not contaminated by dust and dirt when the cover is removed Visual switch activation permits installer to accurately set the retard, even under extremely noisy conditions Rugged, dual SPDT switches are enclosed in a durable terminal block for added strength 100% synchronization activates both alarm panel and local bell simultaneously Robust Construction. The WFDE series consists of a rugged, IP54-rated enclosure. Designed for both indoor and outdoor use, the WFDE series operates across a wide temperature range, from 0 C to 68 C (32 F to 155 F). Reliable Performance. WFDE models are equipped with tamperresistant cover screws to prevent unauthorized entry. Inside, two sets of SPDT (Form C) synchronized switches are enclosed in a durable terminal block to ensure reliable performance. False Alarm Immunity. The WFDE series incorporates a mechanical retard feature, which minimizes the risk of false alarm due to pressure surges or air trapped in the sprinkler system. In addition, the mechanical retard s unique sealed design is immune to dust and other contaminants. Simplified Operation. The WFDE series is designed to simplify installation. Two conduit openings permit easy attachment to the local alarm system. The retard mechanism and dual SPDT switches are field-replaceable.

13 PSP1 Plug-in Special Purpose Supervisory Switch System Sensor s PSP1 plug-in switch is a special application supervisory switch designed for applications where no other type of listed valve supervisory switch can be installed. Features Monitors non-rising stem gate and ball and angle valves NEMA 3 rated enclosures 360 mounting design provides greater installation flexibility Adjustable length supervisory cord Lockout feature ensures alarm signal integrity Cover tamper switch factory installed Tamper-resistant cover screws Application Flexibility. The PSP1 is to be used on non-rising stem gate valves and ball and angle valves. The unit is approved for Class A and Class B circuits. Robust Construction. The PSP1 consists of a rugged rain tight metal housing. With its NEMA 3 rated housing and water-resistant cord, the PSP1 may be used in either indoor or outdoor applications. Simplified Operation. The PSP1 features a 360 versatile mounting design and an adjustable length cord which allow more freedom to install the unit at the most desirable alignment angle. Reliable Performance. The PSP1 employs a supervisory cord which, when pulled out, closes a set of normally open contacts. A lockout feature prevents reinsertion of the cord until the cover is removed, and the unit is reset. Removal of the cover or cutting of the cord results in an open circuit.

14 PSP1 Specifications Architectural/Engineering Specifications Model shall be a model number PSP1 special purpose supervisory switch as manufactured by System Sensor. The unit is not intended or designed for ordinary usage. It is a special application device to be used for unusual conditions where no other approved or listed method of protection is available or practical, such as non-rising stem gate valves. When installed on a non-rising stem gate valve, turning the valve wheel will pull the plug out of the jack and close a set of normally open contacts. A lockout will prevent reinsertion and will require removal of the cover. Tamper-proof screws are provided for the cover. Removal of the cover, cutting of the cord, or ground faults will cause an open circuit. The device should be wired to the trouble circuit of a fire alarm control panel. The PSP1 shall be capable of operating on Class A or Class B circuits. The PSP1 shall be NEMA 3 rated for indoor/outdoor use and shall have an operating temperature range of 4 F to 149 F ( 20 C to 65 C).
