Silent Knight A05-1007 MDL3

Sync Module Sync module synchronizes SpectrAlert strobes at 1 Hz and horns and chimes at 3 over a single pair of wires Patented module also allows the silencing of horns or on horn strobe and chime strobe models over pair of wires operation from module to the devices horns and chimes over a two wire loop strobes at 1 Hz horns and chimes to temporal 3 pattern technology modules for multiple zone synchronization controls two Style Y Class B circuits or one Style Z A circuit NAC slave feature enables the interconnection of slave over a supervised NAC loop MDL3 Module is designed to work with the SpectrAlert and Advance series of noti appliances to provide a of synchronizing the temporal coded horns and chimes the one second timing of the strobe and the horns and chimes of the horn strobe and chime combination over a two wire circuit while leaving the strobes Flexibility The Sync module is designed to and synchronize either two 3 amp circuits wired in Class B one 3 amp circuit powered as Class A Should more than two require synchronization additional modules can be added interconnecting the input and output terminals between Listings 7300 1653 202 Module Specifications Circuit Module shall be a System Sensor Sync Model listed to UL 464 and UL 1971 and shall be approved for service The module shall synchronize SpectrAlert or SpectrAlert strobes at 1 Hz and horns at temporal 3 Also the module shall be of silencing the horns on horn strobe models while operating the over a single pair of wires The module shall be capable of mounting a 411 411 21 back box and shall control two Style Y class B or Style Z class A circuit The module shall be capable of multiple zone by connecting multiple modules slaves together Slaves be driven from either the slave output of a prior MDL3 or from the NAC of the master Using the NAC enables all wiring to be supervised the slave out terminals are not supervised so their use is con to applications The module shall not operate on a coded power supply Operating Temperature L W 411 21 back box to 120 F 0 to 49 C Voltage Voltage Range 12 V Voltage Range 24 V Load on Loop Patent Nos or 24 VDC and FWR to 17.5 VDC to 33 VDC Amps zone and Chimes Silenced Over Two Wire mix of Horn Strobes Chime Strobes or Strobe only devices is Horn and chime control connects to interruptible power source MODULE HORN CONTROL CONNECTS TO INTERRUPTABLE POWER SOURCE 1 1 B 2 B 3 B 2 1 1 1 2 2 IN JUMP OFF 1 1 2 2 IN JUMP OFF NEXT OR EOL STYLE Y ZONES B NEXT OR EOL MUST BE WITH EITHER COMMON ENCLOSURE MODULES OR WITHIN 20 OF EACH OTHER WITH INSIDE CONDUIT NEXT DEVICE NEXT DEVICE Z ZONES A Mode Using NAC Slave Input 1 2 Z CLASS A 3 1 1 2 2 IN JUMP OFF 1 1 2 2 IN JUMP OFF NEXT OR EOL STYLE Y ZONES B NEXT OR EOL MUST BE WITH EITHER COMMON ENCLOSURE MODULES OR WITHIN 20 OF EACH OTHER WITH INSIDE CONDUIT NEXT DEVICE NEXT DEVICE Z ZONES A 1 2 1 1 2 2 IN JUMP OFF NEXT OR EOL NEXT OR EOL NEXT MDL3 NAC IN OR EOL STYLE Y ZONES B 1 2 1 1 2 2 IN JUMP OFF NEXT SPECTRALERT DEVICE OR EOL Draw and Ordering Information Canadian Canadian mA mA mA Slave mA Clintonville Road Northford CT 06472 800 328 0103 203 484 7161 Fax 800 311 1715 System Sensor speci subject to change without notice Visit systemsensor com for product information including the latest version of this data sheet 2 09 2030
