Interlock control of lighting or key
management systems and air conditioning
equipment
The system can monitor signals that turn off the lights
or lock the key management system and shut down
the air conditioning equipment in the corresponding
area. This prevents wasted electricity if tenants acci-
dentally leave the air conditioning on when they leave.
If the data from the sensors indicate the temperature
is lower outside than inside, the system can automati-
cally shut down the air conditioner and switch on the
air intake fans to save electricity.
If a fire alarm signal is received, the system can auto-
matically shut down the air conditioning or ventilation
equipment in the affected area.
