MULTI-TONE GENERATOR

V-5335500

INTRODUCTION

The Multi-Tone Generator (MTG) is a compact, versatile multi-tone generator as well as a Night Bell for a Telephone System. Six different infor m ation tones plus Night Bell are provided, each of which ar e priori ty sensitiv e and individual ly selectable. The Multi-Tone Generator utilizes m ost paging equipment for all page/all call applications.

NOTE: If the host telephone system does not have a page port, then a Loop S tart Trunk Adapter can be used from the MTG J2 connector to the Loop Start Trunk.

OPERATION

The Multi-Tone Generator produces five differ ent tones by contact closure. The sixth tone (time clock input port) is activated by making, or breaking contacts (see Table 1). Requested tones are switched as indicated by the appropriate contact closure onto the paging audio path and provides a contact closure to turn on the connected paging equipment for the duration of the tone request.

Night Bell Functions

The MTG’s Night Bell function is activ ated through J1, Pins 1, 2 and 3 connector (Night Bell). If the activating signal is a nominal 70 Vac, 20 cycle ringer voltage use Pins 2 & 3. The night bell can also be activated by a key system generating 10 to 30 volts AC at 60 cycles or it can be driven by 24 to 48 Vdc, disregarding polarity on Pins 1 & 2. The customer owned phone system audio and control lines are attached to J2 (Page Input) and are passed unchanged through the MTG to J3 (Page/Tone Output) when it is in the inactive, (Tones/Night Bell Off) state. This mode is referred to as “Page Through”. The MTG, when accessed, will disconnect J2 from J3 and connect the MTG’s audio and control lines to J3.

Time Clock Functions

The MTG’s Time Clock (Timed Pulse) function is activated by momentary make and/or break contact (i.e., transition from N.O. to N.C. and N.C. to N.O.).

The Time Clock (Timed Pulse) function can be activated from a mechanical or electronic time clock and will respond to both the on and off time trip point s. A single transi tion will produce a seven secon d beep tone.

NOTE: An interval greater than 15 seconds is required between activations to allow for proper reset of the clock activated tone circuit.

INSTALLATION

Installation of the MTG dif fers depending on how the MTG will be used. There are two different procedures for installing the MTG with night bell service; when the host telephone system supplies an AC ringing generator or when the host telephone system supplies 24/48 volts DC. In addition, inst allation procedures are included for interfaci ng the MTG to PagePac® paging products.
