Minerva SB520 - Sounder Booster Module
The SB520 sounder booster module is used in conjunction with the standard SM520 to drive one or more alarm sounder devices from the addressable loop rather then directly from control panel outputs. The SB520 is required when the alarm sounder load to be driven from the SM520 is greater then 500mA. Using the SB520 increases the sounder load capacity to 15A.
The SB520 requires a seperate 24Vd.c. supply to operate. The module is not addressable and will therefore not take an address on the loop.
M520 module cover also available, please choose from drop down box.
