Important Information Relating to the Connection of this
Equipment to the Telephone Network
1
This equipment is approved for connection to the Public Switched Telephone Network (PSTN) via direct exchange lines offering
LD (pulse) or MF (tone) dialling facilities.
Note: Although this equipment can use either loop disconnect or DTMF
signalling, only the performance of the DTMF signalling is subject to regulatory requirements for correct operation. It
is therefore strongly recommended that the equipment is set to use DTMF signalling for access to public or private
emergency services. DTMF signalling also provides faster call set up.
2
This equipment has a ringer equivalence number (REN) of 1.5.
The REN indicates how many telephone or other types of equipment may be connected to your telephone line simultaneously.
This may be calculated by adding up all the REN values of the equipment connected to the line. A standard telephone can
operate correctly if the total is 4 or less. If you exceed this number, some or all of the bells or ringers may not operate correctly.
In an installation with ringing detectors or bells of mixed types, it is not possible to guarantee correct operation even with a
REN total of less than 4.
3
During dialling, this equipment may tinkle the bells in other telephones sharing the same line. This is not a fault and we advise
you not to call the Fault Repair Service.
4
It is strongly recommended that this equipment has the exclusive use of a direct exchange line. This equipment is capable
of automatically answering an incoming call (see Section [44] of the Programming Guide). If this feature is enabled and the
system is connected to a non-exclusive exchange line, the number of rings before answering must be left at the maximum (15).
Using setting outside of the above will invalidate the approvals for this equipment.
5
Only the Network Operator, or a person authorised by the network operator is allowed to make the connection from this
apparatus to the PSTN.
6
The approval of this equipment for connection to the PSTN is
INVALIDATED
if the apparatus is subject to any modification
in any material way not authorised by BABT or is used with or connected to internal software that has not been formally accepted
by BABT. Use with external control software or apparatus that causes the operation of the integral modem or call setup
equipment to contravene the requirements of the standards for approval as designated.
All apparatus connected to this equipment and thereby connected directly or indirectly to the PSTN must be approved in
accordance with Section 16 of the Telecommunications Act 1981.
7
It is important that the installer verifies the correct operation of stored telephone numbers subsequent to their entry.
8
The connection to this equipment consist of:
Mains (AC) power
Excessive voltage circuit
Telephone line
TNV circuit
All other connections
SELV (Safety Extra-Low Voltage) circuits
This equipment is only to be installed and serviced by qualified personnel. The main cabinet contains circuits working at
excessive voltages (240VAC mains) and must be kept securely closed to prevent unauthorised access. All connections to
mains circuitry must comply with current IEE regulations. This equipment is intended to be supplied from a 220-250V 50Hz
AC supply rated at 0.5A or greater.
9
This equipment is not suitable for use as an extension to a payphone.
10
This equipment has been approved for the use of the following features:
Auto Dialling
Auto Answering
Repeat Attempt Dialling
Tone Detection
Series Connection Facility
Modem Facility
Alarm Dialling and Signalling Facility
Any other usage will invalidate the approval of this apparatus if as a result it then ceases to comply with the standards against
which approval was granted.
11
Series Connection (“line interrupt”). This equipment has been approved for series connection. The equipment will induce a
12mV drop at 40mA in the loop connection between the main apparatus (e.g. a telephone) and the PSTN.
If the equipment connected in series with this apparatus requires a shunt wire (3 wire connection), it will be necessary for the
installer to make this connection within the control panel. Refer to Connection Details for more information.
Only one series apparatus may be connected between the PSTN and the main apparatus (e.g. a telephone).
12
All connections to the PSTN must be via 0.4 - 0.6mm solid copper core conductors suitable for connection to 2.8mm diameter
screw terminals. Standard core cable is not acceptable.
13
Due to the lack of echo suppression tone, this apparatus may not be suitable for dialling international calls.
14
The definition of a Relevant Branch System (RBS) can be found in BS6789 Section 6.1:1986 Clause 2.4.
15
This apparatus has not been designed for use with a PABX/Switchboard.
