Preparation
Configure an emergency stop
In the event of an emergency, like a fire, AC Smart Premium can stop all connected devices (indoor
units, ERV, DOKITs, AWHPs, and AHUs). The fire detection sensor detects a fire and sends an
closed contacts signal to the AC Smart Premium DI1 port, which stops the operation of all connected
devices.
You must connect the external fire detection sensor to the DI1 port of dry contact terminal on the
back of AC Smart Premium (see graphic below) before you can use the emergency stop.
Caution
The DI1 port should always be open except when a fire occurs.
