Night Ringer Contact
In addition to 90V ring activation of the Night Ring feature, a contact
trigger
ed feature is also available.
The night ringer by default sounds a simulated ring tone, but can be
programmed to sound a chime tone to the night ring zone group (same
as 90V activation).
To connect to the night ring input:
1. Make sure that the power is disconnected.
2. Wire the contact closure used for night ring to the NTR (+5V) and
C terminals on the UTI3
12. Maximum contact resistance for contact
closure activation is 1000 ohms. Open collector type outputs for
controlling a page may also be used.
Note: The Night Ring feature has priority just above background music.There is a
5-second delay after the night ring stops before background music is restored
(to bridge inter-ring pause).

of purposes. Common uses are as a doorbell annunciator or to signal
shift changes. Possible tones include slow whoop, steady tone burst,
chime, and double chime.Tone
1 has a higher priority than Tone 2.The
tone type, as well as the contents of the zone group, are programmable.

summed stereo background music inputs with level controls. Mono
sources can be connected to either the "L" or "R" jacks.

The UTI312 system provides a C-form contact rated at 2A @ 30V DC
and 0.6A @ 125V AC, which can be used to activate external equipment.
The r
ela
y can be pr
ogrammed to change state when specific events or
combination of events (time tone, override, night ring, paging) occur.
