The DSM sync modules provide independent operation of synchronized temporal pattern (code 3) horn and synchronized strobe flash, as well as the ability to silence the horn while maintaining the strobe flash (audible silence) while using only a single pair of wires. The DSM-12/24 sync modules control either one (1) Class A or two (2) Class B NAC circuits. When using the low frequency 520 sounder (LFHSK) the DSM can provide the code three temporal (T3) and also the code four temporal (T4) for carbon monoxide notification.
