Minerva SM520 Sounder Driver Module
The SM520 module is used to provide an output to alarm sounders or visual warning devices in responce to a control signal from the control panel. The devices are controlled directly from the SM520 on the addressable loop rather than from outputs on the control panel, thereby significantly reducing wiring costs.
The output wiring to the alarm devices is fully monitored and the module has the capability to drive up to a maximum of 500mA alarm device load. If higher alarm device loads are required then an SB520 sounder booster module must be used in conjunction with the SM520.
The SM520 requires a separate 24Vd.c. supply to operate. The module is addressable and will therefore take one address on the loop.
M520 module cover also available, please choose from drop down box.
