Other Connections
Night Ringer Contact
In addition to 90V ring activation of the Night Ring feature, a contact
triggered 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).
Tone Trigger Inputs
1 & 2
The UTI3
12 tone trigger inputs produce a variety of tones for a variety
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.
Refer to System Programming section.
To connect to the tone trigger input:
1. Make sure that the power is disconnected.
2.
Wire the contact closure used for tone trigger to the
TONE
1/TONE2 (+5V) and C terminals on the UTI312. Maximum
contact resistance for contact closure activation is
1000 ohms. Open
collector type outputs for controlling a page may also be used.
Background Music Inputs
The UTI3
12 system provides two high-impedance, transformer-isolated,
summed stereo background music inputs with level controls. Mono
sources can be connected to either the "L" or "R" jacks.
UTI3
12 AUX Contacts
The UTI3
12 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 relay can be programmed to change state when specific events or
combination of events (time tone, override, night ring, paging) occur.
Refer to the System Programming section.
