Terminals 7 and 8 are used for the remote A CCESS switch; terminals 9 and 10 are used for the remote
R ESET switch; terminals 11 and 12 are used for the remote D AY /N IGHT switch. The A CCESS and R ESET
switches should be normally open (N.O.) momentary switches. The D AY /N IGHT switch must be a
two-position single pole switch and can be marked to show the operator which mode has been selected. If
using an automatic timing system, the relay contact should be closed during day mode and open during
night mode.
Note: Terminals 7, 9, and 11 are common to all switches; therefore, a 4-wire cable may be used to
connect all 3 remote switches.
When wiring is complete, replace the front cover, and connect the ribbon cable and the telephone cable.
Programming: General Instructions
The Model TI984 Telephone Interface’s programmable features allow it to be tailored to different needs.
The unit is shipped from the factory programmed with a set of default parameters listed in the
Programming Summary Chart on page 13. Read the entire Programming section, record the desired
selections in the column titled User Programming, and then proceed to program the unit. We recommend
that you record your programming choices for future reference.
The TI984 is programmed from a touch-tone (DTMF) telephone. If the programmer is working from an
outside line, the Page/Party
® system must first be accessed by calling the number to which the interface is
connected. A Page/Party ® handset must be taken off-hook and the A CCESS button on the front cover of
the TI984 must be pushed. Ensure that the Page/Party
®
station is set to the designated party line.
Note: If there are no handsets, contact the GAI-Tronics’ Field Service Department for programming
instructions.
The two modes of operation, each with separate parameters and separate programming procedures, are
day mode and night mode. Day mode parameters must be programmed with the TI984 in day mode, and
night mode parameters must be programmed with the unit in night mode. The mode is chosen by
toggling the D
AY /N IGHT switch on the front panel; the LEDs on the front panel indicate day/night mode
and if the unit is in use.
