Product Overview
The MRI-4050 Sync Module is designed to be used with MGC NAC devices. The Sync Module is used to synchronize the strobe flashes with the audio signal pattern. The same protocol is used to silence the horn while maintaining the strobe flashes. It also supports 2-stage alarm function of Alert (20 strokes per minute) and Evac (temp 3). The sync module is installed between the fire alarm system NAC line and the NAC devices. When there is no alarm, the NAC line connected to the sync module is off and no power is applied to the device. When the NAC line turns on, the device is powered and becomes operational. Up to 20-modules can be interconnected to achieve synchronization without the need to program or select a master unit. An LED will indicate activation and master/slave status. Master will flash intermittently while slave will flash at a fast rate. Correct interconnection of devices can be checked by ensuring only one device flashes at the master rate. The silence input can be used to silence the NAC devices on one MRI-4050 without affecting the other MRI-4050 devices that are interconnected. The module can synchronize 1 Class A or 2 Class B NAC lines without the need for programing. This is a hardware only device and does not require programming or setting of switches or jumpers.
