Access 670 Alphanumeric Radio Paging System

The RPE670 transcoder is a single box solution enabling any system with closing contacts or an RS232 port to send a paging call.

The RPE670 is also supplied with PC-Access 670 software enabling you to connect the RPE670 to your PC for full alphanumeric paging from the desktop.

  • 8 open or closing contacts with configurable text message
  • 1 x RS232C interface supporting TAP, ESPA 4.4.4 and MEP serial protocols
  • 2.5 Watt Transmitter HF and UHF versions
  • Mk6 and Mk7 paging code formats
  • Up to 1,000 users
  • Formatted teams of 10, 100 or 1000 users
  • Free format text messaging from originating equipment
  • Quick and simple to install

Machine-originated Information for Mobile Staff
The increased use and investment in computerised control and monitor systems have lead to large efficient gains, but to constantly monitor these systems is not an efficient use of resources. Multitone, using its unparalleled experience in radio communications, has developed the RPE670 Series to provide a time critical link between computerised systems and key staff, without the need for continuously manned monitor stations.

A New Solution
The integration of paging into security systems, fire panels, process controllers, building management, nurse and warden call systems has now moved a step forward with the introduction of the RPE670 Series. This product offers a high quality, cost-effective and easy to install solution to the problem of integrating mobile communications with the growing range of computer based applications.

RS232 Coupled and Multiple Message Types
The RPE670 Series encoder enables any system with an RS232 port to send time critical information directly to an engineer or supervisory staff via a text pager. Information can be presented as either a tone, numeric or text message with 1-way speech an option.

Time Sensitive Data for Mobile Staff
The RPE670 Series allows mobile staff to remotely monitor key systems from anywhere within the workplace. The need to continuously man monitor station is removed. Not only is greater staff efficiency achieved, but also a swift response to emergencies is obtained.

Easy to use interface
A dedicated serial port is required on the originating device and our paging protocol (MEP), TAP, ESPA 4.4.4 should be implemented. We can supply a fully documented support package, to enable easy programming of equipment. In situations where either MEP, TAP or ESPA 4.4.4 protocols cannot be implemented the RPE670 Series can still provide a paging interface via the Field Configurable Protocol Converter (FCPC). This converts ASCII or a data string from an event logging port into relevant paging messages.

Automatic Paging
Access 670 is ideal for connection to a door bell or other call systems to allow mobile personnel to be paged instantly.
Lightweight Pagers
The Access 670 Series system use one of our lightweight, compact 'Microbleep' Pagers. Comfortable to wear in the top pocket or on the belt or alternatively carried in your pocket or small handbag, 'Microbleep' will alert you audibly, visually and by vibrating in its normal mode. When you are in a meeting, you can switch it to the 'Mute' mode and it will alert you visually and by vibrating.

Access 670 Series systems are compatible with both the RPR750 Series paging receivers and the RPR580 Series paging receivers.
