About Fire Alarms
The schoolyard fills with lines of wide-eyed children as the teachers call roll and the fire alarm wails. A fire alarm system is an absolute necessity in public and commercial buildings and especially places where children are present. Fire alarms for schools and offices typically include several fire alarm pull stations located strategically around the building. Homes need to have at least a smoke detector, but alarm systems are available as well. These are usually part of larger security systems that have sensors to guard against burglary or other dangers. Components include a main panel, sensors, a siren, and sometimes strobe lights to mount on the wall. Many systems involve a contract with a call center so that emergency services are automatically contacted in case the smoke detector goes off, whether or not anyone is at home to make the call. Find a wide selection on eBay of industrial and residential fire alarm systems, as well as vintage and antique alarms and bells for collectors.
