Ok, going back on topic, some advice if you are planning on bringing a fire alarm to school.
1: make sure the alarms you’re bringing are distinguishable from the ones in the building, so that way you are not mistaken for stealing a device from the school.
2: don’t bring a horn/strobe, bring a remote strobe so that way you don’t disturb the occupancy of the building (unless you were given permission to use a horn/strobe), but stick with remote strobes or just wire your power to the strobe terminals if you have a 4-wire horn/strobe.
3: don’t bring a fire alarm to school for fun, bring it if you have something meaningful to use it for, I brought mine for a science project, if you’re planning on bringing in an alarm to prank someone, don’t do it, it’s not worth it, use common sense.
