GENERAL DESCRIPTION
The Electric Alarm Bell of notification appliances offers a
wide range of Sound, for wall and ceiling applications,
indoors and outdoors. They are designed to be used in 24
volt DC systems.
Loop Design and Wiring
The system designer must make sure that the total current
drawn by the devices on the loop does not exceed the
current capability of the panel supply, and that the last
device on the circuit is operated within its rated voltage.
When calculating the voltage available to the last device,
it is necessary to consider the voltage drop due to the
resistance of the wire. The thicker the wire, the smaller
the voltage drops. Wire resistance tables can be obtained
from electrical handbooks.
INSTALLATION
NOTE
: All wiring must conform to applicable local
codes, ordinances, and regulations.
