PMR Radio

PMR Radio:

We offer a unique range of hybridised PMR radio systems that combine uniquely voice and/or data over a single channel.  Our unique adaptations and interfaces permit PMR Base Station to automatically send messages received from a wide range of smart sensors, transducers, security devices, fire systems, including manual loan worker a emergency pollution call points. This permits both general information and automated emergency call messaging to be overlaid over your existing PMR system. Systems are availble to EN 300 220, EN 300 113 and MPT1411.

PMR has many advantages over the use of cell and DECT telephones. In hazardous areas where explosive atmospheres are present and cell phones and DECT areoften banned. We however can offer ATEX safety certified PMR Receivers. When security is the issued and cell phones are this time banned due to their integrated cameras, then again PMR has the answer. Finally, on many sites where cellular coverage is marginal or non-existent then a PMR system can provide a very cost effective solution with a typical OFCOM site licence as little as £0.30 per week

Message formats can vary from a simple tone to a pre-recorded voice message, both of which open the squelch on the receiver.

Trigger Options include:

Smart Sensors 

Where the parameter/s being measured is optionally broadcast at regular intervals for information to staff. And/or instant alarm messages sent when the value exceeds a specified limit. Measured / Triggered Parameters can include:

Temperature

  • Industrial Processes
  • Thermal Stratification

Humidity

  • Within store rooms
  • Fruit ripening stores
  • Grain stores / silos

PH

  1. Storage tanks
  2. Industrial processes

Drains for spill detection

  1. Dissolved oxygen
  2. Watercourses for spill detection
  3. Rivers, lakes
  4. Commercial fish farms

Pollution Level

  • Oil Interceptor
  • FOG trap Level

Pollution Containment

  • Valve Position
  • System Status

Electricity

  • Consumption
  • Power Failure
  • Maximum Demand Limit Exceeded

Level

  •  Water level
  •  Low Oil Level

Flooding

  •   Basement Flooding
  •   High river level
  •   Blocked Drains / Sewer Flooding

Blocked Drains / Sewers

  •  Warnings whenever a high level is detected                                 

Fire Alarm 

PMR messages can be triggered automatically upon the sounding of a fire alarm. This can be initiated an acoustic coupling transmitter that eliminates the need for a physical connection to the fire system.

Heat Fire Sensors 

To protect bunded chemical stores, industrial composting, outbuildings, hay barns etc. These are bi-metallic sensors, sealed within a metallic housing to IP55 or higher standard to prevent dust, insects etc.

Covert Security          

Stand alone and covert security systems can be created with the PMR system used to deliver warning messages to security staff of intrusion/entry of restricted areas /stores. This can include the use of RFID tagging where the message contains the tag ID that has entered a protected zone
