Skanti TRP 9250, Technical Manual, Page: 130 / 289

The "Remote" annunciator is switched off in the display and TRP9250 may be operated manually.
TRP9250 will reenter "DSC/Telex" mode immediately when a new command from PCP 717S is
received.
NOTE: 2182 distress operation
When the "2182" key is pressed, TRP9250 will enter the distress mode and ignore all commands
except a transmitter frequency command, which will make the TRP 9250 return to remote controlled
mode. A return from distress mode to remote controlled mode may also be performed by pressing
the "TLX" key.
On-Hook:
When the installation includes an external DSC Controller and the TRP9250 receiver is used for
DSC scanning, an On-Hook signal is needed. The On-Hook signal shows if the handset is oper-
ated and is available in the AUX connector (pin 1 ) of the Transceiver Unit.
Handset hooked on: On-Hook = high
Handset hooked off: On-Hook = low
The On-Hook signal is available in all modes ( value = 0 through 6 programmed ).
More Control Units
When TRP9250 includes the optional built-in DSC/Telex Controller-Receiver, TRP9250 will react
on any control command received, regardless of the Priority System state and current programming.
Control commands will even overrule all programmed Security Codes and enable normal operation
securing transmission of a DSC message.
When a handset is lifted off-hook on a TCU an Off-Hook signal is generated and is available to the
optional built-in DSC/Telex Controller-Receiver. The DSC/Telex Controller-Receiver will on
reception of this signal stop scanning control of the TRP9250 MF/HF receiver, and thus enable
manual control of the transceiver. To transfer control to the TCU in question press any key,
preferably the "Enter" key.
