Wheelock Notifier – Series DSM and DSMX Synchronization (Sync) Module

Branchport Avenue Branch N J 07740 631 2148 Thank you for using our products INSTRUCTIONS DSM AND DSMX SYNCHRONIZATION SYNC MODULE this product according to this instruction manual Please keep this instruction manual for future reference Dual Sync Modules Series DSM are uniquely designed to accept two independent strobe and audible inputs and convert to a single output that connects to our Series AS and NS appliances When interfaced with the DSM the AS and NS produce the code 3 horn and synchronized strobe upon actuation The audible portion of the AS and NS can be controlled from the strobe using only a 2 wire alarm circuit They are the ideal choice for alarm systems where an audible silencing is required during an alarm condition The DSM is designed for use with Class A or Class B wiring and they are capable of multiple alarm circuits if required They can be used with 12VDC or 24VDC systems The DSM is UL Listed under 1971 Emergency Appliances for the Hearing Impaired for indoor use Fire Protective Service All inputs are polarized for with standard reverse polarity supervision of circuit wiring by a Fire Alarm Control Panel FACP 1 Products Available for Use with DSM

Inrush See Figures 1A and 1B for the time duration of the peak and inrush current MAKE SURE THAT THE TOTAL CURRENT REQUIRED BY ALL APPLIANCES THAT ARE CONNECTED TO A DOES NOT EXCEED 3.0A PER CIRCUIT OR EXCEED THE RATING OF THE FIRE ALARM CONTROL PANEL PRIMARY SECONDARY POWER SOURCES AND NAC CIRCUITS OVERLOADING THESE SOURCES COULD RESULT IN LOSS OF AND FAILURE TO ALERT OCCUPANTS DURING AN EMERGENCY WHICH COULD RESULT IN PROPERTY DAMAGE SERIOUS INJURY OR DEATH TO YOU AND OR OTHERS calculating the total average peak or inrush currents Use Table 3 to determine the highest value of Average Current an individual strobe across the expected operating voltage range of the strobe to determine the highest value of Inrush or Peak Current whichever is higher of an individual strobe across the expected voltage range of the strobe then these values by the total number of strobes be sure to add the currents for any other appliances including audible signaling powered by the same source and include any required safety factors the inrush current or peak current exceeds the power supplies inrush capacity the output voltage provided by the power supplies drop below the listed voltage range of the appliances connected to the supply and the voltage may not recover in some types of supplies For example an auxiliary power supply that lacks filtering at its output stage either via lack of capacitance and or lack battery backup across the output may exhibit this characteristic 1A Typical In Rush Current Curve 1B Typical Peak Current Curve REFER TO TABLE 3 FOR ACTUAL VALUES REFER TO TABLE 3 FOR ACTUAL VALUES milliseconds milliseconds M 2 of 8 INFORMATION Non sync appliances can be installed before or after an SM or DSM If the Non Sync appliance requires audible silence four connection is necessary with the strobe circuit connected before the SM or DSM NAC circuit and the audible leads connected to silenceable NAC circuit from the FACP Power Supply may be used in conjunction with the DSM Sync Modules ONLY in the order shown in Figure 2 Only DSM Sync Module shall be allowed on a signaling circuit Do not connect the Power Supply to the signaling circuit after the one Sync Module Exception The Wheelock PS 12 24 8 Power Supply can be connected either before or after the DSM Sync Refer to Power Supply instruction manuals for proper application or installation

wiring diagrams for specific applications Sync screw terminals can accept two 18 AWG wires for in out Strip leads 3 8 inches for connection to screw terminals 3 Multiple Alarm Circuits Synchronization Up to 20 DSM SYNC MODULE 1 SYNC MODULE 2 SYNC MODULE LOOP MAXIMUM The total length of wire connecting the DSM SYNC terminals should not exceed 1,000 feet of 18 American Wire Gauge overall between the first and last DSM If this limit is exceeded loss of synchronization between DSM may result M 3 of 8 Class B Wiring single DSM unit can be used with one or two Class B signal circuits DSM terminals
