RELAY OUTPUT
A relay output is ONLY available on a REMOTE INTERCOM connected as an extension to the combined intercom.
The N/O clean contact output can be activated by the manager/control centre when a speech channel is open.
The N/O contacts are on terminals 16 & 17 - contact rating: 30VDC @500mA.
TRIGGER 3 OUTPUT
An open collector output can be activated for 5 seconds when the OPEN button is pressed on the Remote Control with no
other call in progress. Terminal 16 of the combined intercom can be connected to a Tynetec A00073 universal relay to
give a clean contact output. The clean contacts can be used to release a local door lock.
If DIL switch 7 is “ON” the green
Door Open LED will illuminate and a tone will sound on the combined intercom when the Trigger 3 output is active.
PROGRAMMING
Th
e total number of intercom units and their ID’s must be set in the “General Setup & Tenants Unit Identity”
programming. See the Advent xt Programming Manual (Doc No. FM0411).
BEEPING COMBINED INTERCOMS
If a combin
ed intercom “beeps” every 10 seconds then its ID has been set greater than the number of i
ntercoms set in the
system programming. If an intercom beeps every few minutes it is not receiving data (or the data is corrupt).
REMOTE INTERCOMS
One remote intercom (P/No. ZXT221/226) can be connected per combined intercom, see the Advent xt wiring diagrams
Drg No. ZXT100 sheet 5.
IMPORTANT:
combined intercoms (ZXT280-290) and door entry telephones (ZXT220/221)
CANNOT be connected as a remote extension.
