Resumen del manual
Make sure that the power is disconnected and all other connections are completed before proceeding. Move the slide switches on the UTI312 to the positions shown below. Use a modular telephone cord to connect the module to the phone system.The center two conductors are used for dry audio and are not polarity sensitive.The Trunk Disconnect feature is not available in this mode. Note:The default time-out is factory set to 30 seconds,and the VOX time-out is set to 6 seconds.If both the default and VOX timers are inhibited, there is no way to release the system from the page port VOX. 9 Override Input The Override is a feature that lets the caller take priority over all other paging functions and make a page. The center two conductors interface directly to a Loop Start Trunk or a dedicated phone.When the trunk becomes active, the UTI312 goes into Override mode. A contact closure and dry audio source can also be used for the Override Input. The two conductors flanking the talk battery conductors provide a dry audio gateway into the system override. Override is activated by shorting the outermost conductors. Maximum contact closure resistance is 1000 ohms. Open collector type outputs for controlling a page may also be used.The Override feature includes a quad beep pre-announce tone that can be enabled or disabled. (The default is enabled.) Make sure that the power is disconnected and all other connections are completed before proceeding. Plug modular cord into OVERRIDE (RJ11) jack. 90V Night Ring Input The 90V Night Ring Input connects to an analog station line from the PBX or directly to a central office phone line. The UTI312 will follow the incoming ring signal cadence with a simulated ring or chime tone to the Night Ring zone group. 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). 10 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 UTI312. 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 UTI312 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 TONE1/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 UTI312 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. UTI312 AUX Contacts 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 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. 11 ZX3 Module Connections ZX3 Module Paging Output Connections There are three zone paging outputs on the ZX3 module. The paging outputs are intended to connect to self-amplified speakers, but are also compatible with amplifier inputs as well. The Tip (T) and Ring (R) connections are transformer-isolated audio outputs for driving up to 150 self-amplified speaker inputs. ZX3 AUX Contacts Each zone on the ZX3 module has a C-form contact rated at 1A @ 30V DC and 0.5A @ 125V AC. They change state when the corresponding zone becomes active.The ZX3 AUX contacts are not programmable. ZX3 Power Supply Output A 24V DC, 1A regulated power supply, built into the UTI312, can be used to supply power to self-amplified speakers through a 2-pin plug-in connector on the ZX3 module.The + and - terminals provide 24V DC for powering the self-amplified speakers.The UTI312 can supply a total of 1A @ 24V DC through all of these connectors. 12 Controls ...
