PTT for Standby Transmitter
By default U1 provides the PTT signal to key up the standby transmitter for the alarm
beep tones. This feature can be disabled by fitting link JP4. In this case the alarm beep
tones will only be transmitted when the standby receiver or other device keys up the
standby transmitter.
HSS reaction time switching to Standby Mode
R25 (or RV1 if fitted) adjusts the trigger reaction time up to 10 seconds. This allows
for short duration power outages without triggering the alarm condition.

Voltage Regulator

The dc supply to U3 voltage regulator is derived from +12V input pins 1, 14 (from the
MAIN repeater) and Ext_Batt input pin 11 (from the STANDBY repeater). The
Ext_Batt input continues to supply dc to the HSS if the main repeater power supplies
have failed. This allows the alarm beep tones function to continue.

Reset HSS

The rear mounted RESET push button switch may be used to reset the HSS to the
MAIN position. Alternately the RESET signal line on Pin 24 and D10 may be taken
LOW momentarily for a remote RESET function. This line is protected by diode D10.
NOTE:
The main repeater must be in good operational condition before the RESET function
can be enacted otherwise the HSS will detect any alarm or fault condition and shall
NOT switch to MAIN mode.

Alignment Procedure

There is no alignment procedure. The HSS is factory set up to operate automatically
for most situations. The user adjustments are covered in the previous section.
5 Installation
1 Locate and mount the HSS securely in a suitable position between or near the
MAIN and STANDBY repeaters.
2 Attach to the DB-25 connector the appropriate wiring for power supplies and
signal inputs. Attach to the DB-9 connector more signal lines if required.
3 Connect the rf cables to the HSS N-type connectors between Antenna and
Transmitters and also between Antenna and Receivers. Please note the MAIN
and STANDBY connector positions carefully.
4 Check that the MAIN repeater is operating normally – no alarm or fault
conditions.
