System 9000TS
47
Group Relays
Six of the common relays can be configured, as group relays and each channel can be
set to drive any of these relays. The relays typically provide summary alarm contacts
for use by 3
rd
party devices. An example of this would be alarm groups determined by
the alarm type, temperature, pressure, or level.
Reflash Facility
Each of the common group relays can be software configured to reflash every time a
new alarm occurs within the same group, which allows the associated contacts to
return to normal for approx 500ms and then return to the alarm state.
Fault Relays
Any of the common relays can be configured to provide volt free contact outputs which
will change state in the event of a printer fault or primary event buffer overflow.
Watchdog Relay
Each 9000TS System is equipped with a watchdog relay as standard and this relay will
activate in the event of an internal error or communication failure.
RS485 Communication Option
A modbus communication port, Port 1, is provided on the front of the P925TS-X
Interface Card to allow 3
rd
party data to be transmitted to 3
rd
party devices if required.
RS232 Printer Port
A standard 25 pin printer port is provided on the front of the P925TS-X Interface Card
to allow direct connection to a suitable dot matrix printer for dynamic printing of events
as they occur.
RS232 Programming Port
A 9 pin programming port, Port 2 is provided on the front of the P925TS-X Interface
Card to allow the system to be programmed using the RTK supplied windows style
software utility and a suitable lap top computer or PC.
Control Inputs
Any digital input channel can be configured to operate as a pushbutton input to provide
control of the associated lamp / LED outputs. The input can be configured for use as
Lamp Test, System Test, Silence, Acknowledge, Reset, First Reset, Lamp & Audible
Test or as a Sleep Mode control input.
Group Inhibits
Each system is provided with eight inhibit groups which allows the user to configure
multiple digital inputs to each group to inhibit the alarms during prolonged
maintenance periods.
Once an inhibit group has been formed any spare input channel can be configured as
the inhibit group control input and a remote inhibit switch can be used to inhibit all of
the alarms within the group as required.
