2. Introduction:

The JL188 Electric bell of notification appliances offers a wide range of sound, for wall

and ceiling applications, indoors and outdorrs. They are designed to be used in 24 volt DC system.

3. 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.

4. Installation:

Note: All wiring must conform to applicable local codes, ordinances, and regulations.
