The sounder strobe remains the most commonly used
alarm for fire evacuation system, for wall or ceiling
applications, indoors.
The sounder strobe is intended for use in addressable,
2-wire systems where the individual address of each
device is written inside the MCU’s EEPROM by the
addressable programmer.
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.
