BATTERYLESS TELEPHONE SYSTEM

Phontech Batteryless Tele-

phone System: BTS 4000

System BTS 4000 is an emergency telephone system

without the requirement for any external power supply.

All energy required for 4-6 minutes of continuous ope-

ration is produced by the call generator. The system is

equipped with a sophisticated, extremely low power

ampliﬁer with high power and low distortion output. The

ampliﬁer is integrated in one of the telephone units to

reduce the installation cabling. The system may also

be connected to 24VDC power supply to ensure conti-

nuous operation under normal conditions. The system

automatically switches to batteryless and emergency

operation in case of mains failure.

The system is based on three types of units; 4050 –

single line (direct call), 4060 -12 lines version and 4040

-24 lines version. Any conﬁguration needs one master

telephone with a built-in ampliﬁer, either 4051 –single

line or 4061 – 12 lines version. For 24 lines version a

separate speech ampliﬁer type 4000 is needed.
