2 SECTON B/W Controls VERSATLE NEW ALARM DETECTS MOSTURE, LEAKS AND HGH LEVELS, PLUS OFF-NORMAL COND TONS NVOLVNG A WDE VARETY OF PROCESS VARABLES AND BULD NG SECURTY APPLCATONS BW Series 41 Solid-State Alarm Systems are designed to provide new versatility, safety and reliability in monitoring and detecting off-normal conditions in a broad range of industrial, commercial and institutional applications. Key feature of the system is its low energy adjustable sensing circuit which assures reliable operation from electrodes contacting conductive liquids or from contact-type pilot devices such as flow, float, pressure and limit switches, thermostats and pushbutton actuators, etc. As a result, the system can be used to detect moisture or leaks in mines, underground communication networks, boat bilges, computer rooms, libraries, archives and record storage areas. t is also ideal for monitoring dangerous high level conditions in storage tanks, cooling towers, storm drain sumps, septic tanks, sewer systems, lakes, streams, and other locations requiring detection of overflow or flooding. n addition, because Series 41 Alarms will also operate from contact-type pilot devices, they are equally suitable for use in monitoring process variables such as temperature, pressure, flow, humidity, voltage and current, etc., as well as building security and fire detection alarms. nstallation is quick and easy with saddle clamp barrier terminal blocks for 1 to 18 gauge wire, or ring terminal connections to field wiring. OPERATNG FEATURES AND ADVANTAGES BW Series 41 Alarm Systems also provide field-adjustable sensitivity from 1000 ohms up to 1 megohm to assure reliable operation over long distances and in detecting leaks or high levels of a wide variety of conductive liquids. A field-adjustable time-delay is also provided to eliminate false trips due to liquid turbulence or electrical transients. The alarm action does not start until the time delay is completed. Other features include: A SPOT auxiliary relay which has its coil energized when the process condition is normal so that its contact can be used to provide fail-safe remote signal, alarm or cut-off of pumps, valves, motors and other operating equipment in the event of a component or power failure. A holding circuit which permits operation over a range of levels or from momentary contact switching devices. lluminated SLENCE and TEST pushbuttons and optional manual RESET button. SNGLE ALARM PERFORMS MULTPLE FUNCTONS Regardless of usage, however, a single alarm system may be applied with several electrodes or pilot devices connected in parallel to provide an audible alarm in the event a fault condition occurs at one or more of the remote detection points being monitored. Moreover, the low voltage and low current level of the sensing circuit permits use of low cost small gauge unshielded communication wires for long distance alarm installations.

NDUSTRAL & WEATHERPROOF MODEL For outdoor or indoor service in a fiberglass enclosure and with choice of a horn or a 6 inch bell. DESCRPTON OF OPERATON STANDARD SEQUENCE is automatic reset with silence pushbutton and without lock-in, SA designation A-1-4, with the extra feature of an adjustable time delay after the fault condition occurs which delays the alarm action for the set time period. The auxiliary SPOT contact is a fail safe arrangement that follows the alarm light status. The test pushbutton provides full operational test simulating an abnormal condition. MANUAL RESET SEQUENCE operates the same as the standard sequence except that a momentary fault condition will lock-in the alarm status until the condition returns to normal, and the reset pushbutton is operated. The SA sequence designation is M-1.

3 B/W Controls SECTON 3 TYPCAL APPLCATONS Diagrams below illustrate basic details of typical installations ir1 which Series 41 Alarm Systems are used to monitor and detect any off-normal conditions in applications involving the control of liquids and various common in-process variables. ~ J... SUGGESTED CONTROL SETTNGS Sensitivity: Set to a value greater than the specific resistance of the liquid to be controlled. Time Delay: Normally 0- second or just long enough to prevent nuisance alarms resulting from wave action of the liquid. n Diagram A, the system consists of one electrode set at the predetermined danger level and a second common electrode set at the same or a slightly lower level to complete the sensing circuit. n Diagram B, the jumper is removed from terminal block and a third reset electrode is used. The alarm will then go off automatically when liquid falls below the reset electrode. Diagram C is essentially the same except a normally-closed pushbutton is used to lock in alarm instead of a reset electrode. n Diagram D, a good ground return to the liquid is used to complete the sensing circuit instead of a common electrode.
