Controller is Alarming - buzzing
The Controller is initially provided with a yellow link fitted across the Door Sense terminals.
This provides a short circuit, and if removed should be replaced by fitting a door sense
contact.
Door Lock 1 has a built in Local door alarm (buzzer), which if the contact is left open for
more than 15 seconds will “sound” out. To stop the buzzer change the door s
ensor type
(close to open); fit a link, or simply close the door.
