Drop calculations for System Sensor AV products can be done using the Honeywell
Online Tools for Fire (HOTFire) site.
HOTFire is a free online site that enables users to quickly plan and
model notification appliance circuits (NACs) using the entire line of
SpectrAlert® Advance and L-Series. Other notification appliances can be loaded
by each user. Its simple step-by-step
process makes it easy for users to configure panels and circuits from a variety
of devices to meet any specification requirement.
