UTI1 Feature Callouts 1. Power Indicator - Illuminates when AC power has been applied to the unit. 2. AUX Contact Terminals - Provide connections for normally open and normally closed contact closures.The contact closure can be programmed to activate during paging, night ring, tone, override, or any combination (refer to System Programming). 3. Ground Start Terminal - Connection for PBX ground. Used only when the ground start interface is selected. 4.
Introduction The UTI1 Paging System is a paging and signaling system.
Installation Wall Mounting Mounting to a plywood backboard or studs: 1. 2. 3. 4. Hold the unit level against the surface to which it will be mounted. Mark where the mounting screws should be positioned. Set the unit aside and install the screws leaving about 1/4" of the screws sticking out of the surface. Slip the unit over the screws and tighten them snugly.
Telephone Interface Wiring Connections & Setup Telephone System Connections The UTI1 connects to virtually any telephone system: PBX station lines and CO lines, PBX loop start trunk ports, PBX ground start trunk ports, and page ports. Interface installation consists of setting the slide switches and connecting with modular (RJ11) telephone plugs. Refer to the appropriate procedure in this section to connect the UTI1 to the telephone system.
PBX Ground Start Trunk Port In this configuration, the unit supplies 24V talk battery, a contact in the Tip circuit, and loop current detector in the ring line. When the ground start trunk grounds Ring, the unit responds by closing the connection to Tip, which completes the access procedure.When the loop is opened, the page ends.The unit follows the status of the trunk. Before proceeding, make sure that the power is disconnected and all other connections are completed.
PBX Page Port VOX In this configuration, the unit activates when audio on the page input is detected. Loss of audio allows the VOX timer to expire and ends the page. Make sure that the power is disconnected and all other connections are completed before proceeding. Move the slide switches on the UTI1 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.
Override Input The Override is a non-programmable feature that lets the caller take priority over all paging functions and make a page to all speakers.The feature can be activated using a loop start trunk or dedicated telephone. The center two conductors interface directly to a Loop Start Trunk or a dedicated phone.When the trunk becomes active, the UTI1 goes into Override mode.A contact closure and dry audio source can also be used for the Override Input.
Other Connections Night Ringer The UTI1 night ringer signaling feature is designed to alert personnel to incoming calls after normal business hours.The feature is activated by a contact closure from the PBX. The night ringer normally sounds a simulated ring tone, but can be programmed to sound a chime tone. To physically connect the night ringer wiring: 1. 2. Make sure that the power is disconnected. Wire the contact closure used for night ring to the NTR (+5V) and C terminals on the UTI1.
Controls Paging Level The UTI1 has controls for adjusting the audio level of each output independently. These serve as master level controls that allow for overall system control. Setting the initial volume to half is a good starting point. If the speakers have their own level control, then the installer will have to determine the proper setting for each speaker depending on the application. Clockwise increases level, counterclockwise decreases level.
Tones Pre-Announce/Confirmation Tone This tone can be set to be heard at the speakers being paged or the calling telephone or both. It is either a chime or beep (default).The pre-announce/confirmation tone can also be inhibited. See System Programming to change or inhibit this tone. Tone Trigger This tone is activated when the TN and C terminals are shorted together.This tone has the second highest priority after override. Several tone options are available.
System Programming System programming lets you set certain UTI1 options and tone features using the DTMF keys of a telephone. All programming is accomplished through the Override jack on the UTI1. To program the UTI1 system, follow these instructions: 1. 2. 3. 4. 5. Place the PROGRAM/RUN switch to the PROGRAM position.The green LED will illuminate. Access the UTI1 override port (either use a single 2500-type telephone or Test Set. You will hear 3 beep tones indicating access to the programming mode.
AUX Relay Contact The UTI1 allows the installer to program a number of different parameters to control the way in which the AUX relay contacts activate.
