1___________________________________________OPERATING INSTRUCTIONS
1Operating Instructions
The HSS has two modes of operation, MAIN and STANDBY.
MAIN mode is the normal operation of the MAIN repeater and STANDBY mode is
when the HSS has switched to the standby repeater. There are two front mounted
LEDS. If the main repeater is connected correctly to the HSS the GREEN PWR LED
signifies that the main repeater has no alarms or fault conditions. If an alarm or fault
condition arises in the main repeater the RED ALM LED will light up and the HSS
switches to STANDBY mode.
The HSS does not need to be actively powered for STANDBY mode so in the event
of complete power supply failure to the main repeater the HSS defaults to STANDBY
automatically. For continued operation the standby repeater should have a battery
backup system and/or separate power supply.

3Circuit Description
The following descriptions should be read as an aid to understanding the schematic
diagram at the rear of this manual.
3.1 Coaxial Relays
The coaxial relays switch the RF signal path between two repeaters. A separate relay
is used for antenna –receivers and another for antenna –transmitters. Both relays are
powered ON in normal operation, in the MAIN mode. Transistors Q10 and Q11 drive
each relay. In STANDBY mode the relays default to OFF position so are particularly
suitable for monitoring an ac or dc power failure condition.
3.2 Line Relays
The relays RL1, RL2, RL3 and RL4 provide the input/ output signal line switching
facility. Transistor Q9 drives these relays in unison with Q10 and Q11 operation.
All relays operate together. Either all are ON or all are OFF.
The schematic shows the relays in STANDBY or OFF position.
Four signal lines are switched through RL1, RL2 and the DB-25 connector. Another
three signal lines are available for user expansion switched through RL3 and the DB-9
connector.
3.3 Alarm and Fault Triggers
ATI Alarm output
The HSS is designed to work with the Eclipse Alarm Trunking Interface (ATI) and
can also be easily interfaced to third party equipment. The ATI combines the receiver
and transmitter alarm signals and the output is brought to a common pin (ATI card
DB-25 Pin 4). The ATI also monitors and will alarm if either the receiver or
transmitter is disconnected from the rack frame connector.
In alarm condition the standard ATI output is Alarm_High.

5 flashes, pause Synthesizer unlocked

2 flashes, pause High reverse (reflected) power

LED ON continuously Transmitter timed out
Input Signal Lines
The alarm inputs are diode protected. Two Alarm_Low inputs (pin 9 and pin 22 at D6
and D7) and two Alarm_High inputs (pin 10 and pin 23 at D8 and D9) are provided so
that third party equipment may also be monitored.
The external Eclipse power amplifier may be monitored through two lines at
pin 8, T/R_Relay_Main and pin 21, RFO_Main. Both lines must be connected for
proper operation. Q1, Q7 & Q2 provide the logic for alarm condition.
To force the HSS into STANDBY mode the Force_Stby line pin 12 and D11 should
be connected to GND momentarily. This line is protected by diode D11.
3.4 Alarm Outputs
Alarm Double Beep Audio Tone
Any main repeater alarm or fault condition will cause the HSS to switch to
STANDBY. If link JP2 (Alarm Beep Enable) is fitted, a double beep tone of
approximately 8 seconds interval is mixed in with the audio on the standby repeater
(pin 2, Stby_DirAudio_out). RV3 adjusts the beep tone level.
Power Loss Alarm Double Beep Audio Tone
Loss of ac power to the main repeater or dc power supply failure in the main repeater
will cause the HSS to switch to STANDBY. If links JP1 (Low voltage detector) and
JP2 (Alarm Beep Enable) are fitted, a double beep tone of approximately 2 seconds
interval is mixed in with the audio on the standby repeater (pin 2,
Stby_DirAudio_out). RV3 adjusts the beep tone level.
RV2 sets the threshold of the low voltage detector circuit.

5 INSTALLATION_____________________________________________________
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.
3.5 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.
3.6 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.
4Alignment 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.
5Installation
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.

INSTALLATION_
5 Check the HSS GREEN PWR LED is lit ON.
6 Press the RESET push button switch on the rear of the HSS to switch it to
MAIN repeater. The RED ALM LED should be OFF and the main repeater is
functioning properly. This is the normal operation mode.
7 Test the STANDBY mode by introducing an alarm in the main repeater. If an
ATI is fitted simply pull out the receiver or transmitter sufficiently to
disconnect it from the rack frame connector and an alarm will occur. The HSS
should switch to STANDBY and the RED ALM LED should light ON.
8 If JP1 and JP2 are set correctly the HSS will introduce a double beep audio
tone mixed with the standby transmitter audio. This is the STANDBY mode.
9 To RESET the HSS, restore the main repeater to normal operation (no alarms)
before pressing the RESET push button switch.
10 This ends the installation but the remote RESET (FORCE_MAIN) and remote
FORCE_STANDBY can be tested in a similar way.
