PTTI Page/Talk Telephone Interface

Guardian’s PTTI Page/Talk Telephone Interface is designed to connect to a public or private telephone system.

FEATURES and BENEFITS
The PTTI is a telephone interface that connects a Page/Talk system to a public or private telephone system. Outgoing calls can be made from the Page/Talk system to outside telephone lines via an attendant who has access to the phone system and telephone interface, to place and link the call to the Page/Talk system. Once the call has been answered the operator can press the link button to connect the outside line to the systems designated talk line – the designated talk line is the only talk line in a single line system or any one of the lines in a multi-line system, at the installer’s option. Incoming calls from the outside can reach the Page/Talk system either through operator intervention or in one of four accessing modes which can be pre-programmed into the PTTI. When the call is answered it will be transferred to the designated talk line of the system. The operator can disconnect a call at any time by pressing the release button. The PTTI interface provides four different modes of access to the Page/Talk system for each of day and night configurations.
• MANUAL ACCESS: requires operator intervention to answer an incoming call and then manually linking the call to the Page/Talk system.
• RING ACCESS: does not require operator intervention or ID code to connect, as it is automated and will put a ring signal on the page line until answered.
• VOICE ACCESS: does not require operator intervention or ID code to connect, as it is automated and will connect incoming calls and allow the caller to place a voice page onto the page line directly.
• SELECTIVE ACCESS: requires the calling party to know the ID number, therefore adding a level of security to the Page/Talk system.

INSTALLATION and CONNECTABILITY
Guardian’s modular approach to system design gives you the flexibility to set up systems based on exactly what is needed – as well as the ability to integrate equipment already in place.

Accessories

AG17 Multi-Tone Alarm Generator

The Guardian Telecom AG17 is a reliable ten-tone signal generator designed to work with your general alarm and public address systems. Alarm tone, priority, duration and triggering are all user programmable to meet specific operating safety, and workplace conditions. An Audio override facility also allows voice-paging during tone activation, giving you the ability to deliver voice instructions through Page/Talk intercom stations or other paging sources by completely muting or attenuating the active tone.

FEATURES and BENEFITS
• Ten tone alarm library
• User programmable microprocessor to customize tone priority, duration, triggering, muting and attenuation
• Eight channels for output signal priority
• Logic output mirrors control inputs
• Momentary or latching inputs
• 120/240 VAC
• LED alarm activation indicators
• Output level control
• Compact - fits on a standard 19” equipment rack - 2 rack units (2U)
• Audio override for Page/Talk announcements

APPLICATIONS
Guardian Telecom’s AG17 Multi-Tone Alarm Generator provides a ten tone library of the most commonly used alarm signals and tones to increase the overall capability and effectiveness of your alarm and paging systems.
User programming is straightforward if any of the AG17’s pre-set industry standard defaults need to be changed. You have complete control over which tones activate when alarms and warning conditions specific to your work environment occur. The AG17 lets you determine which signal is given the highest priority and automatically overrides lower priority tones when a higher priority channel activates. Clearly visible LED’s on the front panel indicate the status of each channel.

Override audio/logic inputs have a higher priority than alarm tone signals and suppress any existing alarm tone to broadcast the override. An active alarm can be completely muted or attenuated by 10 dB, 20 dB, or 60 dB to accommodate an override broadcast. The ability to use voice-paging during tone activation means you can deliver messages through Page/Talk intercom stations or other paging sources, even during an emergency situation when clear voice instructions can be critically important.

INSTALLATION and CONNECTABILITY
The AG17 multi-Tone Alarm Generator is one component in Guardian Telecom’s full line of reliable, hard working paging system products - all designed for easy installation and connectivity. The AG17 can be ordered separately or as part of an integrated system that includes Page/Talk stations, speakers and speaker amplifier units, and distribution amplifiers. Guardian’s trained representatives will work with you to customize your operation’s general alarm and paging systems.
