Note: The Alarm input 1 to 4 and clear input are pulled high
internally. Connect the external alarm devices to these
pins.The quad will detect the type of external alarm equipment
automatically in power-on initialization but can be changed in
programming also.
The internal relay was set to NC position normally for the
Alarm output. So pin 1 and 3 will short normally, and will be
opened when an event was occurred.
Pin 2 will be open normally, and will be closed when an alarm
occurs.
Warning: The rating of the internal relay is:
AC 120V @ 1A or DC 30V @ 1A. The user must take care in
not overloading this relay for safety reasons.
