PC POP-UPs

Alarms and site information is displayed on a central PC, or on your home PC if you have dialled into the network. 

INTERNAL DIAL-UP MODEMS

Where these are fitted to the central unit, technicians can dial in from home and access the entire network. Non radio sites can also dial in to register alarm events.

SMART TELEMETRY 

These units are intelligent and function in isolation to any PC, the PC is only used for displaying and configuration. All features such as voice alarms and relay mapping are generated directly by the unit. For the most part the PC may be turned off. Over a 100 Pop-ups may be stored by the final BT-62 which bleeps until a PC is turned on.

REMOTE RELAY ALARMS 

Alarm inputs can be mapped to any relay outputs at any other site on the radio or dial-up telephone network. 

DUAL RADIO CHANGE OVER

The BT-62 contains two VF interfaces which may be used to intercept Omnibus circuits, join or disconnect a repeater or create a change over pair.

STORED VOICE ALARMS

Faults are spoken over the air using our default digitised stored voice or your own stored voice phrases. Alarms can repeat at a programmable rate and interval.

SPOKEN VOICE DIAGNOSTICS

The input value of analogue 0-5-20v inputs are spoken in natural English in response to DTMF codes. A store and repeat function will also echo 8 seconds of your received transmission. 

BASIC SYSTEM

These inputs are link selectable as either a standard A/D inputs or digital opto inputs. As Analogue inputs they can be set for 0-20v or 0-5v for sensors or made to accommodate 4-20ma for industrial interfaces.

TWO 10k SECURITY OPTO INPUTS 

Two of these inputs can be linked as 10k terminated security style inputs, ie a short or open triggers alarm. ( option ) 

RELAY OUTPUT -

This can be set by a DTMF code or from your PC via the internal FFSK radio modem or via dial-up modem.

NEED MORE INPUTS ?

The BT-62 has expansion capacity for six internal I/O cards with a further 6 in an expansion rack. This provides up to 80 inputs or outputs. I/O cards are available as linkable Opto / A/Ds, or fixed or Relays out. 

EASY INSTALLATION

The unit is easily interfaced to an existing radio by intercepting the 6 wire VF connections. When an alarm event occurs the unit will break the 6 wire VF connections, apply a PTT, or simulate a MUTE output and transmit stored voice or data. In the idle state and in the event of power failure, the device is always disconnected by way of relaxed internal relays. This automatically reconnects the radio back to its input. 

CHANGE OVER / SPLITTING NETWORK

Since the unit has two VF interfaces it can separate and rejoin a repeater site from a network by cutting the 6 wire connections. Additional VF change over cards allow a duplicated radio link to be created with manual or automatic change over. Change over can be initiated via a BIT-VISION or DTMF command over the radio link or via a dial-up Telecom modem. .

MAP INPUTS TO RELAY OUTPUTS

Any input may be mapped to any relay output on any site in the radio area, even it's self. Dial up connected sites will ring the appropriate number to set that relay. This is done automatically without any PC interaction. Ie. All the numbers and destination information is held within the BT-62s memory.

PC ALARM MONITORING 

Remote units can contact a PC via the internal FFSK radio modem or via telecom dial-up lines. BIT-VISION will generate POP-UP alarms boxes on your Windows or Win 95 screen, even when you are in another application. The user may also access the remote site to monitor A/D inputs, control relay outputs or alter the A/D trip points. If the PC is off, the final BT unit ( network controller ) will store alarms and bleep. 

MULTIPLE NETWORKS

A PC may access several different networks at once by fitting a BT-62 to the end of each network. These units have an RS485 bus on COM 3 which allows them to be bussed together and automatically route data packets to the right network like a telephone exchange.

FFSK RADIO MODEM OR PSTN DIAL UP

The BT-62 communicates to other BT-62 units via an internal 1200/2400bps FFSK modem. As a back up or for non-radio connected site, the BT-62 can be fitted with a dial-up modem. This can dial up the network controller and register a Pop-up alarm in just the same manner as does a radio site unit. 

Where the network controller BT-62 unit is also fitted with a dial up modem, technicians can dial in from home and obtain a log of events that are queued so far.

VOICE ALARMS 

Each input can generate a voice alarm which can either be the default phrase - 

      " Alarm on input 6 at 11.7 volts "

Or you can record your own phrase over the air.

      " Fred here, the battery's gone flat again "

This can be repeated at programmable intervals. A DTMF or BIT-VISION access stops the repetition. Note - voice alarms and voice diagnostics are available only on radio based systems and not via dialup. 

VOICE DIAGNOSTICS

DTMF codes can cause the BT-62 to speak the value of specific inputs in clear English. e.g. 16# speaks -

        " Card 1 Input 6 is at 12.3 volts "

+ 8 seconds of your own store and forward audio test.
