INSTALLATION INSTRUCTIONS CH70 24MCWH CHIME STROBE 2 All audible and visual signaling appliances must be installed in accordance with all applicable national and local fire alarm and any other required regulatory agencies CH70 24MCWH Multi Candela Electronic Chime Strobe is UL Listed under Standard 1971 for Signaling Devices for the Hearing Im and UL Standard 464 for Private Mode Audible Signal Appliances as well as CAN ULC S526 17 and CAN ULC S525 17 In Canada chime is for Dwelling Use Only The CH70 24MCWH Chime Strobe is designed for low current draw and versatile performance This offers a choice of 1Hz 2Hz coded or temporal code 3 T3 operation has adjustable sound level and has a chime tone of 890Hz The CH70 24MCWH Multi Candela strobe provides four selectable light output intensities in one unit This appliance also incorporates chime mounting plate attached to the chime for ease of installation The Chime Strobe model can provide a non synchronized strobe when connected directly to a fire alarm control panel FACP or provide a synchronized strobe appliance when connected to a appliance circuit running the Cooper Notification sync protocol The chime tone can be synchronized as well using the same strobe uses a xenon flashtube with solid state circuitry enclosed in a polycarbonate lens to provide maximum visibility and reliability for visible signaling The CH70 24MCWH is Listed for indoor use wall mount only with the backboxes specified in these instructions wiring and mounting information CH70 24MCWH model is UL ULC Listed for indoor use with a temperature range of 32 to 122 0 to 50 and maximum of 93 RH The effect of shipping and storage temperatures shall not adversely affect the performance of the appliance when it stored in the original cartons and is not subjected to misuse or abuse NFPA 72 ANSI 117.1 conform to ADAAG Equivalent Facilitation in using fewer higher intensity strobes within the same protected area All CAUTIONS and WARNINGS are identified by the symbol and printed in bold capital letters THE CHIME APPLIANCE IS A ALARM DEVICE DO NOT PAINT Table 1 UL ULC Listed Models and Rating Voltage VRMS Current Only dBA at Feet dBA at 10ft Strobes are not designed to be used on coded systems in which the applied voltage is cycled on and off MAKE SURE THAT THE TOTAL RMS CURRENT REQUIRED BY ALL APPLIANCES THAT ARE CONNECTED TO THE PRIMARY AND SECONDARY POWER SOURCES DO NOT EXCEED THE POWER SOURCES RATED CAPACITY OR THE RATINGS OF ANY FUSES ON THE CIRCUITS TO WHICH THESE APPLIANCES ARE WIRED OVERLOADING POWER OR EXCEEDING FUSE RATINGS COULD RESULT IN LOSS OF POWER AND FAILURE TO ALERT OCCUPANTS DURING EMERGENCY WHICH COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND OR OTHERS Strobes are not designed to be used on coded systems in which the applied voltage is on and off In order to synchronize the Chime tone the Chime device must NOT be set for coded operation Refer to instruction sheets for DSM P83177 or Cooper Notification power supplies P84905 for additional information when synchronization is desired 3 Chime Tone Settings SW1 Position 2 3 T3 chime is factory set in code 3 T3 mode It can be changed before wiring appliance with the dip switch Refer to PC Board layout shown in Figure 1 OPERATION The minimum input pulse duration must be at least 160 time and 160 milliseconds time The chime will only oper once each time it is pulsed This mode is recommended for coded systems 3 1HZ AND 2HZ Continuous input voltage must be applied to the chime activate the chime in these modes volume has been adjusted at the factory to insure maximum dBA output once the mode is selected the installer may want to fine tune the to better suit the application In a synchronized tone application the will default to temporal code 3 no matter what the DIP switches are set to be set to coded 2 UL ULC Current Ratings Strobe Only RMS Current Amps Voltage VDC VDC 1 AND MOUNTING INFORMATION following figures show the maximum number of field wires conductors that can enter the backbox used with each mounting option If limits are exceeded there may be insufficient space in the backbox to accommodate the field wires and stresses from the wires could the product that the installed product will have sufficient clearance and wiring room prior to installing backboxes and conduit especially if multiconductor cable or 3 4 conduit fittings are used CANDELA SETTING WILL DETERMINE THE CURRENT DRAW OF THE PRODUCT strobe will produce 1 flash per second over the Input Voltage range strobes meet the required light distribution patterns defined in UL 1971 chime produces a brief inrush current of 0.100 Amps with filtered DC input 0.140 Amps with full wave rectified VRMS input with a duration of 100 milliseconds The Code 3 temporal pattern 1 2 second on 1 2 second off 1 2 second on 1 2 second off 1 2 second on 1 1 2 off and repeat is by ANSI and NFPA 72 for standard emergency evacuation signaling When calculating the total currents for two wire chime strobe mode use Table 2 to determine the highest value of RMS current for an strobe and add in the chime current from Table 1 multiply this value by total device current for a given NAC Be sure to add the for any other appliances including audible signaling appliances powered by the same source and to include any required safety In four wire mode the total current draw for the strobe circuit and for the chime circuit must be calculated separately appliances were tested to the voltage limits of 16.0 33.0 volts for 24V models using filtered DC or unfiltered Full Wave Rectified Do not apply voltage outside of this range B Branchport Ave Long Branch N J 07740 800 631 2148www coopernotification comCopyright 2018 Cooper

cycled on and off while the strobe continuously Figure 3 Appliance and Strobe Appliance operate in unison Red and black wires are The chime must be set for any other mode than coded Figure 5 NOTE The CH70 24MCWH comes pre set at 135cd THE CANDELA SELECT SWITCH MUST BE FIELD SET TO THE CANDELA INTENSITY BEFORE INSTALLATION WHEN CHANGING SETTING OF THE CANDELA SELECT SWITCH MAKE CERTAIN THAT IT IN PLACE AFTER CHANGING THE CANDELA SETTING THE AP MUST BE RETESTED TO VERIFY PROPER OPERATION Chime Strobe model has in out wiring terminals that accept two 12 to 18 American Wire Gauge wires at each screw terminal Strip leads 3 8 inches and connect to screw terminals all in out wire runs on supervised circuits to assure integrity of circuit supervision as shown in Figure Figure 4 polarity shown in the wiring diagrams is for operation of the appliances The polarity is reversed by the during supervision 90 Figure 6 Light Output In order to synchronize the Chime tone the Chime device must not be set for coded operation see page 3 chime must be set at maximum volume for Private Mode Fire Protective Service per UL 464 listing requirements see page 2 chime produces a brief inrush current of 0.100 Amps with filtered DC input 0.140 Amps with full wave rectified VRMS input with a duration of 100 milliseconds notification appliances are UL Listed as Application They are intended to be used only with Cooper Notification Refer to the installation instructions for the appropriate NAC to find the maximum allowed voltage drop Use this value along with current draw for the appliance to determine the allowable wire resistance PROCEDURES model can be flush mounted to a 4 square by 2 1 8 deep backbox with a 4 square 1 1 2 extension ring surface mounted to a Surface Backbox Mounting for
