3-16-3. Interlock control
The DIDO controller (PAC-YG66DCA) has an interlock control function, which enables operation or set temperature change on the
M-NET devices such as indoor units and also enables signal output to the contacts on the DIDO controller.
Interlock control covers the units connected to the DIDO controller with M-NET system. AG-150A/G(B)-50A/GB-24A must be connected
to use the function.
Ask your dealer for interlock control setting. The setting requires special tool support.
CAUTION
Before using the interlock control, you must agree to the following.
1.This feature must not be used for disaster prevention or security purpose.
(Not designed to be used in situations that are life-threatening)
2.No functions must be added that allow the malfunctioning unit to run by defeating the safety features, such as
an external ON/OFF switch or a short-circuit.
3.Those settings for the function that are not supported by the interlocked units must not be made. All the
settings must be made within the specified range.
(Failure to observe these precautions may result in malfunctions and failures.)
4.Perform a test run for interlock control, and confirm the correct settings and normal operation.
5.The system must be configured in the way that integrates the operation of the interlocked fire and emergency
control systems.
