SECTION 1
GENERAL
Each 4100 Fire Alarm System is a factory-configured, hard-wired fire alarm system that provides for up to 1,000
points. Each point can consist of (a) one or more alarm initiating devices, (b) one or more signal appliances, (c) an
auxiliary relay, or (d) a feedback circuit. In addition, if software changes are needed, it’s possible to reconfigure a
4100 at the job site.
NOTE:
If the system connects to a municipal fire alarm system, the city connection is considered as one point.
