15. INTERCOM UNIT DIL SWITCHES & LINK SETTINGS
Before fitting the intercom front the “Address” and “Options” DIL switches must be set. The jumper links LK1, LK2 & LK3
must also be set in the correct position.
INTERCOM ADDRESS DIL SWITCH
The intercom Address must be set sequentially using an 8 bit binary
code starting from “1” in the lowest flat number on the site.
Note: binary “0” (all DIL switches set OFF) is not used.
INTERCOM OPTIONS DIL SWITCH
Any additional equipment connected to an intercom must be enabled via the Options DIL switch.
When door entry/strobe is disabled (DIL SW 2 OFF) intercom terminals 18 & 19 are enabled as four additional alarm inputs - see section 14.

RELAY OUTPUT
A relay output is available on intercoms WITHOUT a door entry telephone connected. 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.
PROGRAMMING
The 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 INTERCOMS
If an intercom “beeps” every 10 seconds then its ID has been set greater than the number of intercoms set in the system
programming. If an intercom beeps every few minutes it is not receiving data (or the data is corrupt).
