All models are UL Listed for indoor use only with the backboxes specified in these instructions (see Mounting Options).NOTE: All CAUTIONS and WARNINGSThe speaker appliance is a fire alarm device – do not paint.FOLLOWING INSTRUCTIONS, CAUTIONS AND WARNINGS COULD RESULT IN IMPROPER APPLICATION, INSTALLATION AND/OR OPERATION OF THESE PRODUCTS IN AN EMERGENCY SITUATION, WHICH COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS. SPECIFICATIONS:Table 1: UL Listed Models and RatingsSpeakerModel Voltage(VRMS) dBA at 10 Feet(Rated Watts)MountingOptions1/81/41/212E50 25/70 77.0 79.5 82.5 85.0 88.0 A,BNOTES:1.All models are UL Listed for indoor use with a temperature range of +32ºF to +120ºF (0ºC to +49ºC) and maximumhumidity of 85% RH.2.dBA is rated per UL Standard 1480 for Speaker Appliances. Frequency range of speakers is 400 – 400HZCopyright 2004 Wheelock, Inc. All rights reservedWIRING INFORMATION:A 1.5µF blocking capacitor for DC supervision of audio lines by the FACP is factory wired in series with the speaker input. Supervision voltage must not exceed 33 volts DC.Figure 1: Figure 2:COM+FROM PRECEDING SPEAKER TO NEXT SPEAKER *1. Series E50 Speaker models have in-out wiringterminals that accept two #12 to #18 AmericanWire Gauge (AWG) wires at each screw terminal. Strip leads 3/8 inches and connect toscrew terminals.2. Break all in-out wire runs on supervisedcircuits to assure integrity of circuit supervision as shown in Figure 2. The polarityshown in the wiring diagrams is for operationof the appliances.GROUNDING: Connect ground wire to backbox. Install signaling appliance to backbox using mounting screws provided.NOTE: Check electrical ratings specified in tables 1 and 2 (as appropriate) to ensure proper electrical input. Be sure that speaker wiring is connected to speaker terminals only and strobe wiring is connected to strobe terminals only. Check to insure that wiring at FACP is correct.MALFUNCTION.Figure 3: Jumper plug is used to select dBA loudness.Figure 4: Tap Settings (Factory setting is 70V @ 1/2W (F))NOTE: Use needle nose pliers to pull and properly insert the jumper plug to the desired tap setting.Connect speaker wires to common and positive of terminal block and select the power tap terminal for 1/8W, 1/4W, 1/2W, 1W or 2W; 25V or 70V as required (see Figures 1, 2, 3, 4 and Table 2). Each doubling of rated Watts increases sound output by 3 dBA. Each letter corresponds to a plug position of the header located on the printed circuit board. Select voltage and wattage as shown in Table 2 below.Table 2: Speaker Voltage and Wattage Connection ChartPosition 25V 70VA 2 ------B 1 ------C 1/2 ------D 1/4 2E 1/8 1F ------ 1/2G ------ 1/4H ------ 1/8NOTE: The speaker strobe appliances must be set to the desired dBA sound output level before they are installed. This is done by properly inserting jumper plugs in accordance with these instructions.Always operate audio amplifiers and speakers within their specified ratings. Excessive input may distort sound quality and may damage audio equipment. Improper input voltage can damage speaker. If distortion is heard, check for clipping of the audio appliance with an oscilloscope and reduce the amplifier input level or gain level to eliminate any clipping.MOUNTING OPTIONS:The following figures show the maximum number of field wires (conductors) that can enter the backbox used with each mounting option. If these limits are exceeded, there may be insufficient space in the backbox to accommodate the field wires and stresses from the wires could damage the product.Although the limits shown for each mounting option comply with the National Electrical Code (NEC), Wheelock recommends use of the largest backbox option shown and the use of approved stranded field wires, whenever possible, to provide additional wiring room for easy installation and minimum stress on the product from wiring.NOTE: Surface backbox (SSB) in Figure B, is compatible with wiremold and conduit. Mounting holes are for single-gang, double-gang, and #10 wood screws for stud mounting. If metal conduit is installed onto top and bottom conduit entrances, then an insulated grounding wire (18 AWG, supplied) must be connected between the top and bottom plate by using thread cutting screws (supplied) to provide electrical continuity per UL 50. See Figure 5.Figure 5:MOUNTING PROCEDURES:Check that the installed product will have sufficient clearance and wiring room prior to installing backboxes and conduit, especially if sheathed multiconductor cable or 3/4" conduit fittings are used.1. E50 models have an integrated Speaker Mounting Plate.2. The Speaker Mounting Plate must be oriented correctly when it is mounted to the backbox. Refer to mounting options fororientation.3. First mount the Speaker Mounting Plate to the backbox. Next slide the grille over the Speaker Mounting Plate until both snapsare engaged.4. When terminating field wires, do not use more lead length than required. Excess lead length could result in insufficient wiringspace for the signaling appliance.5. Conduit entrances to the backbox should be selected to provide sufficient wiring clearance for the installed product.6. Do not pass additional wires (used for other than the signaling appliance) through the backbox. Such additional wires couldresult in insufficient wiring space for the signaling appliance.7. Mounting hardware for each mounting option is supplied. Use (2) wood screws to mount surface backbox on wall surface.8. All models can be flush mounted to a 4” square by 2-1/8” deep backbox in the wall (Figure A).9. Use care and proper techniques to position the field wires in the backbox so that they use minimum space and produce minimumstress on the product. This is especially important for stiff, heavy gauge wires and wires with thick insulation or sheathing.10 Use care to prevent speaker cone damage when driving screws for speaker product mounting.If this appliance is required to produce a distinctive three-pulse Temporal Pattern Fire Alarm Evacuation Signal (for total evacuation) in accordance with NFPA 72, the appliance must be used with a fire alarm control unit that can generate the temporal pattern signal. Refer to manufacturer’s installation manual for details.NOTE: NFPA 72/ANSI 117.1 conforms to ADAAG Equivalent Facilitation Guidelines in using fewer, higher intensity strobes within the same protected area.Check the installation instructions of the manufacturers of other equipment used in the system for any guidelines or restrictions on wiring and/or locating Notification Appliance Circuits (NAC) and notification appliances. Some system communication circuits and/or audio circuits, for example, may require special precautions to assure electrical noise immunity (e.g. audio crosstalk).NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules.

THROW,DOUBLE POLE DOUBLE THROW LIMIT SWITCHESINTRODUCTIONAll E50 Limit Switches consist of three modular, interchangeable, plug-in components: operating head, switch body, and wiring receptacle.Operating heads (side rotary, top and side push, and wobble stick) aremounted on top of the switch body in any of four positions. Both SPDTand DPDT switch bodies employ snap-acting, leaf contact springsproviding high reliability and extended life. All assembled limit switchesare UL Listed, CSA Certified, and rated with Enclosure Types 3, 3S, 4,4X, 6, 6P and 13. Obtain renewal parts by ordering the catalog numberlabeled on each of the three limit switch components.NEMA ICS 2-225 describes preferred installation recommendationswhich assures greatest reliability and longest life expectancy forIndustrial Limit Switches.TORQUE REQUIREMENTS FOR LIMIT SWITCHASSEMBL YTighten the operating head and switch body screws toa torque value within the following ranges to assure andmaintain the Enclosure Type Ratings for the assembledlimit switch.Switch Body Screws – Tighten to insure contact ofswitch body to wiring receptacle: 25 – 30 in.-lb.Operating Head Screws – Tighten to insure contact ofhead to switch body: 14 – 18 in.-lb.The wiring receptacle provides the mounting means foran assembled limit switch. Two holes provide for frontmounting with #10 screws. Two threaded holes providefor rear mounting using #10 – 32 screws. Sealing ofthe ½ inch NPT or 20mm conduit entrance threadsshould be done by using the E50KH6 conduit sealingnut, sealing compound, or T eflon tape. This willassure and maintain the limit switch Enclosure T ypeRatings.Switch bodies and receptacles are keyed to prevent asingle pole switch from being plugged into a double polereceptacle or vice versa. Receptacle wiring terminals arenumbered and correspond with diagram on switch bodynameplate. Pressure plate terminals accept AWG #18through #12 wire. A grounding screw (colored green)provides enclosure grounding. Limit switches shouldbe rigidly mounted with suitable clearances to permitcomponent replacement.CONNECTION DIAGRAM – SPDT, DPDTThe following connection diagram appears on switch body nameplate.ELECTRICAL DATA - CONTACT RATINGS PER POLEFor pre-wired cable or pin connector versions, refer to wiring label onside or receptacle.Contacts SPDT, DPDT Form Z (Four Terminal, Double-Break-Double Make)Contact Ratings Except gravity return: Without pilot light: NEMAA600, R300; With pilot light: NEMA A150, R150;Gravity return-only: Without pilot light: NEMAB600, With pilot light: NEMA B150Repeat Accuracy0.3% maximum deviationConstruction Die-cast zinc alloyEnclosure Type IP67 / NEMA / UL Enclosure Types 3, 3S, 4, 4X,6, 6P, & 13Operating Temp.See Operating Head Temperature Chart pg. 2TABLE 1 - DESIGN CHARACTERISTICS1 N.O. - 1 N.C.Must be same polarityGreen2 N.O. - 2 N.C.Same polarity each poleGrounding: Eachwiring recep-tacle contains agreen screwterminal provinga GRD connecti-on point ot themetal enclosure.16578SINGLEPOLEKEYGROUNDTERMINALSCREWGROUNDTERMINALSCREWDOUBLE POLEKEYSingle PoleWiring ReceptacleDouble PoleWiring ReceptacleTABLE 2 - SPDT, DPDT - EXCEPT GRAVITY RETURN SWITCHContacts on same polarity 1&21 Gravity Return switches are rated AC only - DC ratings do not apply.2 Switch bodies with indicating light are for application on 120V or less.AC (NEMA A600) DC (NEMA R300)Volts Current Amperes Voltamperes CurrentMake Break Cont.Make Break Volts Amperes1206061200.252403032400.12548015 1.510720072060012 1.2TABLE 3 - GRAVITY RETURN SWITCH ONLY - NEMA B600 RATINGAC Current Amperes VoltamperesVolts Make Break Cont.Make Break12030324015 1.54807.50.75 5360036060060.60Instructions Publication P15836Effective November 2011INSTRUCTION E50 SINGLE POLE DOUBLE T HROW,DOUBLE POLE DOUBLE T HROW LIMIT SWITCHESEATON CORPORATION SWITCH BODIES WITH INDICATING LIGHTSwitch bodies with the indicating light should be used at 120V or less.

The push roller style can be converted from vertical to horizontal operation or vice versa. Pull roller out of the head until it can be rotated 90° to the desired orientation. When released, it will snap into the set position. The Maintained Contact head has the reset pushbutton located opposite of the actuator pushbutton.INSTRUCTION E50 SINGLE POLE DOUBLE T HROW,DOUBLE POLE DOUBLE T HROW LIMIT SWITCHESInstructions Publication P15836Effective November 2011Mechanical life can be extended if the following guidelines are followed:a.) Cam arrangement should be such that: the actuator does not receive a severe impact; the actuator does not suddenly slip back freely.b.) Minimum amount of overtravel should be used. See NEMA ICS 2-225 for additional guidelines.SPECIAL PURPOSE LIMIT SWITCHESGravity Return Limit Switch - These limit switches require a very low operating force. Table 8. The weight of the rod-type lever supplies the return force instead of a return spring. Limit switchoperation is either CW or CCW, and may be mounted in any position where the shaft is horizontal (parallel to ground).Adjustment – After mounting in the selected position, adjust for proper operation. Set the rod extension and lock it in place with set-screw. Loosen other setscrew and rotate the INPUT SHAFT in the direction it will turn when operated (clockwise or counterclockwise) until a resistance is felt and a click is heard (contacts trip). Back the shaft away from this point until the contacts reset as indicated by another click – This is about 10°, the minimum pretravel for the Gravity Return limit switch. The shaft may be set for any desired pre-travel between 10° and 170° - at more than 170° the contacts may trip. In noisy locations, where the click of contact operation might not be heard, connect a test lamp in series with the normally open contacts for visual indication of contact operation. With the shaft set for the desired amount of pretravel, 10° to 170°, lock the operator in place with setscrew. Check for repeatable switch operation. Neutral Position Limit Switch - This spring return limit switch has two independently operated poles. One pole operates when the shaft rotates clockwise, and the other operates when the shaft is rotated counterclockwise. Both poles are reset in the neutral posi-tion (center off). See Table 8 below.T wo Step Limit Switch - The mode of operation of this side rotary operated two pole limit switch can be changed for CW, CCW or CW and CCW mode as described for the standard side rotary head on page 2. Two independently-operated poles function as a degree of head shaft rotation. One pole operates after 10° of shaft rotation and the second after an additional 10° of shaft rotation in the same direc-tion (20° total for step two). Both poles reset when the shaft returns to the spring return or neutral position.Side PushWobble HeadTABLE 7 - OPERATING HEAD DATAInstructions Publication P15836Effective November 2011INSTRUCTION E50 SINGLE POLE DOUBLE T HROW,DOUBLE POLE DOUBLE T HROW LIMIT SWITCHESTABLE 8 - OPERATING DATA - SPECIAL PURPOSE LIMIT SWITCHESGravity ReturnMust be Same Polarity CW CCWNeutral PositionTwo Step312 For CW or CCW only operation.
