DOORPHONES APPLICATIONS
Ed. 046/8 Réf. 3EH 21000 BSAA
USING AN NPTT DOORPHONE
The doorphone interface comprises an intercom and an optional doorstrike powered by the mains
supply through a SELV (Safety Extra Low Voltage) transformer.
A single doorphone with doorstrike may be connected to the system.
The system also allows for the connection of 2 doorphones without doorstrikes.
Operating principle
Pressing the doorphone call button triggers a loop on the associated Z terminal. The loop is maintai-
ned by relay 1 on the AFU board until the call is answered. The Z terminal is in immediate selection
mode on the doorphone destination group or terminal.
There is a specific key for answering the call, while another controls the automatic doorstrike (latch)
via relay 2 on the AFU board.
