12 Types of Outstation
There are two types of outstation:
Type A - comprises a telephone handset in a red wall-mounted cabinet. Type A enclosures may be
lockable, in which case keys must be issued by the person responsible for safety at the site.
Type B - comprises a wall-mounted intercom-style unit with a CALL button and built-in microphone and
loudspeaker.
13 Making a Call from an Outstation
There is no need to dial from an outstation as the system automatically calls the Operator at a wall or desk control
unit.
At Type A outstations, pick up the
handset and a double ‘beep-beep’ ringing tone sounds in the earpiece.
At Type B outstations, press the
‘Push to Call or Answer’ button and a double ‘beep-beep’ ringing tone sounds in
the loudspeaker and the
‘Call in Progress’ indicator is lit steady.
At the wall control unit (or desk control unit), the ringer sounds and the Operator can choose to answer.
If the Operator is talking to another outstation, an engaged tone sounds at the
outstation’s earpiece.
The Operator knows there is a call, so stay on the line until it is answered.
14 Answering a Call at an Outstation
When the Operator at the wall control unit (or desk control unit) calls an outstation, a ringing tone is heard at the
outstation. At the outstation, either pick up the handset (at Type A outstations) or press
‘Push to Call or Answer’
button (at Type B outstations).
