Wheelock DSM sync modules data sheet

Technical Data TD450081EN Sync modules DSM sync modules provide independent operation of temporal pattern code 3 horn and synchronized flash as well as the ability to silence the horn while the strobe flash audible silence while using only a pair of wires The DSM 12 24 sync modules control either 1 Class A or two 2 Class B NAC circuits When using the frequency 520 sounder LFHSK the DSM can provide the three temporal T3 and also the code four temporal T4 carbon monoxide notification 1 Products available for use with DSM sync module HS with strobea and EH with strobe with strobe strobes strobes a

Current consumption DSM modules Circuit Description of DSM Module with Audible Silence with No Audible Silence with Audible Silence with No Audible Silence circuit circuit circuit circuit Module DSM dual sync modules are rated for 3.0 amperes per circuit The maximum number of interconnected DSM modules is twenty 20 Non sync appliances can be installed before or after a DSM If the non sync appliance requires audible silence four wire connection is necessary with the strobe circuit connected before the DSM NAC circuit and the audible leads connected to a silenceable NAC circuit from the FACP The audible appliance produces a momentary interruption approximately 25ms each time the strobes flash Circuit 2 may be omitted if only 1 circuit is required when using the DSM Non sync audible appliances can be installed on the audible NAC Be aware of the current requirement for the DSM module See Table 2 www eaton comWheelock DSMfirealarmresources com Data TD450081EN October 2016 4 Specifications and Ordering Information Number Code Voltage VDC Current 12 or 24 VDC Maxa Optionsb RMS current ratings are per UL average RMS method UL max current rating is the maximum RMS current within the listed voltage range 16 for 24v units For strobes the UL max current is usually at minimum listed voltage 16v for 24v units For audibles the max current is usually at the maximum listed voltage 33v for 24v units For unfiltered FWR ratings see installation instructions Refer to Data Sheet TD450028EN for mounting options The total distance from the first to the last DSM shall not exceed 1,000 feet of 18 AWG wire Use only 18 AWG wire and engineers specifications sync modules shall be Wheelock DSM sync modules Wheelock DSM sync modules shall be the master controllers for
