<br />0411,0412 <br /> <br />Synchronization Modules <br /> <br />Specifications <br /> <br />Features <br /> <br />· Synchronization modules for Class A and Class B alarm <br />circuits <br /> <br />· Compatible with Radionics D500 Series Horn/Strobes <br /> <br />· Independent control of audible alarm while maintaining visual <br />alarm on two-wire or four-wire Notification Appliance Circuit <br />(NAC) <br /> <br />· Operates on 12 or 24 VDC <br /> <br />· Converts two independent inputs, strobe and audible, into a <br />single notification appliance output <br /> <br />· Conforms with ADA synchronization guidelines for strobes <br />and audible Temporal Code 3 output <br /> <br />· Supervision of Synchronization Module(s) by the Fire Alarm <br />Control Panel (FACP) <br /> <br />Description <br /> <br />Radionics' D411 is a 12/24 VDC module that synchronizes <br />notification appliances on Class B alarm circuits. <br /> <br />Radionics' 0412 is a 12/24 VDC module that synchronizes <br />notification appliances on a single Class A or two Class B <br />circuits. <br /> <br />These devices provide an effective means of synchronizing <br />both audible and strobe circuits. <br /> <br />Audible devices controlled by these modules provide a <br />synchronized Temporal Code 3 output. This means that the <br />Code 3 pattern produced by all horns on that circuit is <br />synchronized and the temporal pattern effect mandated by <br />NFPA 72 (July, 1996) is clearly recognizable. <br /> <br />Synchronizing strobes can eliminate possible restrictions on <br />the number of strobes in the field of view. This is an easy way <br />to comply with ADA recommendations concerning persons <br />with photosensitive epilepsy. <br /> <br />Both the two-wire and four-wire modules offer the ability to <br />provide independent operation of audible notification <br />appliances while maintaining the visual alarm condition, a <br />required feature in some jurisdictions. <br /> <br />The D412s may be interconnected to provide temporal (Code <br />3) horn and strobe synchronization with multiple circuits. <br /> <br />By using existing wiring, these modules also provide an <br />economical method of upgrading existing two- or four-wire <br />circuits to comply with new regulations. <br /> <br /> <br />Front View of Synchronization Module <br /> <br />Application <br /> <br />Radionics' D411 and D412 Synchronization Modules are used <br />in Notification Appliance Circuits to control synchronization of <br />audible and visual devices. They bring visual strobes into <br />synchronization with an output of one flash per second and <br />audible devices into compliance with NFPA 72, temporal sound <br />pattern (Code 3). <br /> <br />They provide a cost effective means to upgrade existing circuits <br />to ADA compliance. <br /> <br />The 0411 and 0412 Synchronization Modules operate on <br />notification appliance circuits with continuously applied <br />voltage. <br /> <br />Installation <br /> <br />The D411 flush or surface mounts to a 4 in. x 2 -1/8 in. back <br />box; the D412 flush or surface mounts to a 4-11/16 in. x 2-1/8 <br />in. back box. <br /> <br />Notification appliance outputs from the control panel connect <br />to the modules and outputs from the modules connect to the <br />notification appliance circuit. <br /> <br />Install, test and maintain these devices according to their <br />Installation Guides, NFPA 72, Local Codes and the Authority <br />Having Jurisdiction. Failure to follow these procedures may <br />result in failure of the devices to operate properly. Radionics is <br />not responsible for devices that are improperly installed, tested <br />and maintained. <br /> <br />$ radionics <br /> <br />A member of the <br />Bosch Group <br />
