INSTALLATION AND MAINTENANCE INSTRUCTIONS
Addressable Sounder Strobe
Notice: This manual should be left with the owner/user of this equipment.
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, two-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.

This information is included as a quick reference installation guide. Refer to the control panel
installation manual for detailed system information. If the sounder strobes will be installed in an
existing operational system, inform the operator and local authority that the system will be
temporarily out of service. Disconnect power to the control panel before installing the sounder
Figure 2 Dimensions of sounder strobe
Figure3 Terminal and configuration of sounder strobe
Mode 1: 2 wires of loop, do not need connect to external
Power supply, it has sounder function only without strobe.
Mode 2 : 4 wires, 2 wires of loop,2 wires of external power
Supply, have sounder and strobe functions (default);
