Radio Telemetry We offer an extensive range of Radio Telemetry systems manufactured specifically for pollution control applications. This wireless technology has been engineered to the most exacting industrial standards and operates over licence free radio spectrum in the VHF band that is specifically reserved by OFCOM for Industrial Telemetry and Telecommand applications. Included in this range are wireless spill activation call points, ultra-low power receivers, acoustic fire alarm triggers, repeaters and wireless sensor interfaces. Standard features include:
•
Low Power Radio signal proven not to cause interference to existing services or equipment,
•
Narrow band VHF carrier designed to give maximum building penetration.
•
Secure "closed" radio protocol with 4-billion combination secure addressing scheme
•
Rolling security code
•
16-bit CRC error check sum
•
Optional fault reporting and GPRS messaging service
•
Automatic repeat of alarm messages
•
Optional Test Channel
•
Regular health messages
•
Range optimisation through antenna choice
•
Up to 2Km range LoS
Wireless Call Point RTU These can be placed at strategic points around a site permitting an incident to be reported and/or to activate the pollution control valve at the press of a button. Supplied complete with integrated long life lithium battery and sealed to IP65 these units can be mounted almost anywhere without the need for expensive cabling thus eliminating the need for staff to cross a hazardous area to raise an alarm. The system permits an unlimited number of call points to be used and can be used in conjunction with repeaters to extend range.
Wireless Sensor Interface RTU This unit accepts an alarm signal (closing contact) from a level switch, oil interceptor alarm, PH sensor etc and forwards it seamlessly to the pollution control system. As with the call points there is no limit to the number of units operating on a system and the unit can be either battery or dc operated.
Wireless Acoustic Alarm Coupler RTU
With fire water containment, it is essential to have 24/7 system activation that does not rely upon human intervention. The best and simplest way to achieve this is to use our unique wireless acoustic coupler that listens out for the sounding of the fire alarm and relays this message to the containment system control panel. By using acoustic technology we eliminate the substantial cost of adding repeater relays to a fire alarm system.
Wireless Repeater Unit This unit has been designed to assist with the improvement of wireless coverage on large industrial sites. By installing this unit at roof top, it is possible to extend the range of the wireless network to over 5sq km in open areas and in built up areas depending upon topology from between 500m sq to 2Km sq.
