Safety Notice
- Do not work on the extension wiring or connect/disconnect the ST 31during a thunder storm.
- Install extension wiring of the ST 31in a manner that it is not walked on or causing anybody to trip
over them.
- Ensure that no liquids are allowed to enter the housing of the ST 31Digital System Phone as
otherwise short circuiting may result.
The digital System Phone ST 31 is intended for the connection to an internal S0-Bus of an AGFEO
ISDN Telephone System. The ST 31 may be connected to the following AGFEO ISDN Telephone
Systems:
- AS 151, AS 181, AS 1x, AS 2x from Firmware 6.3
- AS 151 plus, AS 181 plus, AS 181 plus EIB-In-One from Firmware 8.0
- AS 281 All-In-One, AS 35, AS 35 All-In-One from Firmware 7.6
- AS 40 P (P400-1), AS 4000 (P400-1), AS 100 IT (P400 IT), AS 43, AS 45, AS 200 IT fromFirmware 7.6
- all other AGFEO Telephone Systems with a Firmware below 7.1 will emulate the ST 31 as an ST 30
System Phone. Please refer to Page 18 for a description of function changes.
The AGFEO ST 31 System Phone will have a max. power consumption of 1.7 Watt when under full
load, such like all LED’s are lit, optional answering machine module A-40 installed and the phone
ringing at full volume. The max. output for a S0 540 (S0440) module is 4.5 Watt for each two ports
combined. This would mean that in the worst case scenario two ST 31’s and one ST 30 (max. 1.3
Watt) could exceed the maximum limit set. This could activate the overload protection circuit and
shut down the power supply to the relevant combined ports. (System Phones none functional / S0
Bus no power. Power will be restored after system reset) In such eventualities it is suggested to
connect an external power source to the ISDN Bus.
A power supply unit may be obtained from your distributor, AGFEO Ref. No. 1542431. (Identical to
STE 30 / DECT S0 Base Power Supply Unit)
Information regarding software upgrades are available via your dealer.
AGFEO will not accept any liability for damages which may result from improper use of the digital
System Phone ST 31.
