The DFT-120 eliminates the acoustical feedback loop c

reated by the telephone

handset and the paging speaker, while providing high-capacity, high-quality recording

and playback of audio pages.

FEATURES

• High sampling rate for excellent playback quality

• Ability to record a message while another is played

• Wall-mountable

The TAMB interfaces a telephone system with a paging

system, allowing

announcements to be made through any telephone. Any of these types of analog ports

can be connected using the TAMB: loop-start trunk, ground-start trunk and station

port (90 V ring-up). This wide range of port compatibility makes the TAMB

indispensable for any telephone paging application because it eliminates the

possibility of mismatching paging interfaces and port types.

FEATURES

• Loop-start, ground-start and station port (90 V ring-up) compatibility

• 600-ohms output

• Built-in confirmation tone indicating access to paging system (defeatable)

• Built-in pre-announce tone produced over paging system before

announcement (defeatable)

• Adjustable tone volume

BOGEN PR7980V2-8075.eps

The TG-4C is designed to produce four different type

s of tones for use as alarm or

announcement signals in paging systems. An audio signal can be routed through the

TG-4C to allow easy installation in paging systems. During generation of the tones,

the routed audio will be suppressed.

FEATURES

• Four types of tones: steady, pulsed alarm, slow whoop and chime

• Tones triggered by external contact closure (momentary or long duration)

• Choice of continuous generation of tones or two-burst operation (except for

steady tone)

• 600-ohms output

Paging Control Modules;Zone Paging/10991

BOGEN PR7992V2-8111.eps

The ZPM3 allows for economical one- or two-way paging

(with TBA 15 Talk-Back

Amplifier) to be directed into any of up to three different paging areas. Zones can be

grouped together so that more than one zone is paged at the same time. All areas can

also be paged at once. Zone selection can be made using DTMF tones or pulse dialing.

FEATURES

• Three-zone paging plus All-Call

• Three easily programmable zone groups (one to three zones in each)

• 100 W total power handling capability

• Background music input
