Wheelock MB bells installation sheet

INSTALLATION INSTRUCTIONS MB MOTOR BELLS this product according to this instruction manual Please keep this instruction manual for future MB Motor Bells are UL Listed under Standard 464 for Fire Protective Signaling or General Sig Use and ULC Listed under Standard CAN ULC S525 07 for Audible Signaling Appliances with exception of the models MB G6 6 and MBL G10 12 S ADM which are UL approved for General Use only The Motor Bell Series incorporates a high torque permanent magnet motor to pro high output with minimum current draw Integral MOV suppression is provided to minimize RFI and transients In out wiring terminals and a built in trim plate for semi flush mounting are provided easy installation The Motor Bell Series is available in 6VDC with a 6 inch bell shell and 12VDC or with either a 6 inch or 10 inch bell shell Please read these instructions carefully Failure to comply with any of the following cautions and warnings could result in improper application installation and or op of these products in an emergency situation which could result in property damage and injury or death to you and or others The MB Motor Bell is a fire alarm device DO NOT PAINT 1 UL ULC Listed Models and Ratings Range Current ULC dBA UL 464 6 inches 6 inches inches 10 inches 4.2 7.8 6 inches inches the model number is not ULC Listed These appliances were tested to the operating voltage limits of 16 33 Volts for 24V 8 17.5V for 12V models or 4.2 7.8V for 6V models using filtered DC or unfiltered full FWR Do not apply 80 and 110 of these voltage values for system operation Ensure the total RMS current and total average current required by all appliances that connected to the system primary and secondary power sources NAC circuits SM DSM modules or Cooper Wheelock power supplies do not exceed the power sources rated or the current ratings of any fuses on the circuits to which these appliances are wired power sources or exceeding fuse ratings could result in loss of power and failure to occupants during an emergency which could result in property damage and serious injury death to you and or others Branchport Ave Branch N J 07740 631 2148 calculating the total currents Use Table 1 to determine the highest value of RMS Current or Current for an individual bell across the expected operating voltage range of the bell Then these values by the total number of bells be sure to add the currents for any other appliances audible signaling appliances powered by the same source and include any required safety the peak current exceeds the power supplies peak capacity the output voltage provided by the pow supplies may drop below the listed voltage range of the appliances connected to the supply and the may not recover in some types of power supplies For example an auxiliary power supply that filtering at its output stage either via lack of capacitance and or lack of battery backup across the may exhibit this characteristic DIAGRAM R O M P R E C E D

method shall be in accordance with CSA C22.1 Canadian Electrical Code Part 1 Safety for Electrical Installations Section 32 PROCEDURES If sheathed multiconductor cable or 3 4 inch conduit fittings are used verify the installed has sufficient clearance and wiring room prior to installing backboxes and conduit weather resistant installation use outdoor mounting option Outdoor backbox must be vertically with as marked to allow any moisture or condensation to drain properly drain holes on bottom of backbox bell mechanism is adjusted to operate only with the shell provided Do not mix shells and during installation Do not readjust bell mechanisms during installation polarity shown in the wiring diagram is for the proper operation of the signals current of all bells is approximately 4 times rated current This inrush current surge exists about 0.006 seconds and must be supplied by the system power supply to ensure start up all devices If the system power supply does not have sufficient surge capability generally by large filter capacitors loading of the supply should be based on the DC bell inrush rather than on their rated steady state current Ensure the system power supply is with the specified inrush current bells operate on full wave rectified unfiltered DC as well as pure filtered DC Motor Bells will over a voltage range of 6VDC 4.2 7.8VDC 12VDC 8 17.5VDC 24VDC 16 33VDC only within specified voltage range for rated performance and endurance Performance are based on nominal input voltage bells will operate on systems up to 2 on off cycles per second
