The RL system is the original IceSpy wireless recording system. Many of the functions and components of RL have been improved with System5, but RL systems and components are well proven and are still available.

Data sheets for the RL system can be found on the downloads page.

IceSpy RL monitoring system was the first wireless recording system on the market and revolutionised multi-channel recording by providing freedom from cable connections between sensors.

This cost-effective radio solution provides links between the sensing devices (temperature, humidity and door openings) and the recording and display systems. It drastically reduces the installation of cables that waste resources and limit your freedom.

• No wiring or expensive installation costs. IceSpy RL is quick and easy to install. Up to 32 sensors linked by radio to a base collection unit, conveniently sited in your office. Several base units can be used on a single site, to provide a limitless number of monitoring points.
• Base unit continuously displays current temperatures, locking on to critical channels in the event of alarms. Stored records are available at all times, accessed by your computer or direct printing.
• High and low alarms provide instant visual warnings and optional audio warnings. Independent external alarm messages can be sent, or data downloaded, anywhere in the world via modem connections or GSM short message service.
• Radio repeaters extend the standard 100 metres radio range to cover virtually any site.
• Different monitoring environments are catered for with a range of temperature probes and also a combination humidity/temperature probe.
• Door openings can be monitored along with temperatures; you can determine the percentage of time doors have been left open (when they shouldn't have been).
• All sensors are waterproof and tamperproof with a sealed 10-year battery. Base units and repeaters are battery-backed so can record or send alarms during power failures.
• Easy-to-use software for Windows™ for PC will enable you to view temperature performance, zoom in on periods of interest, analyse temperature graphs, and select data to print. Also allows you to set up alarms, sensor names, locations and references.

• The base unit can also connect direct to a printer, producing a tabulated listing of all the temperatures and alarms stored.
• Humidity versions available (RL and HL Logger)

Standards

• Sensors are sealed to IP68 standards.      
• Temperature accuracy meets UK Food Hygiene Regulations.                                                                                             
• Meets EC directives for electronic & low-power radio equipment.
• Every sensor is guaranteed to be within its specified accuracy.
• Calibration certificates, traceable to national standards, are available for all sensors.

Battery Life

• Battery life of temperature sensors is at least ten years. The base unit and radio repeaters are mains-powered, with backup batteries for 8-12 hours

Data storage and reading

• When memory fills up, the units will discard the oldest data and keep the newest
• You can download manually or automatically: either when there is an alarm or at regular times each day. The data can be used with your existing PC programs (spreadsheets or word processors): there is an option to save all data or just alarm data.

Installation

• RL sensors are easy to self-install, using standard clips or cable-ties. Repeaters and base units require a source of mains power. A basic knowledge of installing and using Windows software will enable the completion of system set-up.
• Alternatively a full installation service can be provided, to guarantee you a first-class system, with the minimum of fuss.

Technical support

• All units are covered by a 12-month guarantee for parts and labour, backed by full technical help service by telephone or email. We also provide annual on-site support contracts.

System expansion

• Additional sensors can be added: up to 32 in total for each base unit, with a limitless number of base units. See specifications for extension sensor types.

Radio specification

• Radio transmitters operate on 433.92MHz licence free band and are fully approved for all EC countries (under the R&TTE directive) and many others. The RL system is interference-free from other equipment including mobile phones.
• Radio range is affected by many factors. In open level ground it is at least 200 metres, but will be reduced by obstacles such as walls of buildings and cold room enclosures. Distance and effectiveness can be improved by the use of repeaters to boost the signal.

How do I order the RL system?

• Decide how many points you wish to monitor: temperatures, humidity and doors. Mark the monitoring points and types (e.g. ovens, freezers) on a scale plan. Send us the plan and ask us to provide a quotation.
• We will create a customised system specification, and let you know what options are available.

Keep in touch with your system from anywhere

A modem is one of the options available with the IceSpy RL Series. Once our battery-backed modem is connected a whole range of extra features become possible:

• Sending of Alarm information to remote locations, even when there is a power failure.
• Notification of alarm conditions can be sent to any location equipped with a PC and modem as soon as they occur. Both recorder and modem have backup batteries so can operate during power failure.
• Collecting a set of readings using a remote PC (Downloading) at any time.
• You may dial into the logger at any time to collect (download) a set of readings from the logger.
• Changing the operating parameters from a remote PC (Uploading) at any time..
• Again, using a PC and attached modem you may check and/or alter the current operating parameters of the logger at any time from a remote location. Parameters such as logging interval, number of sensors and alarm levels can all be altered remotely.
• Sending timed downloads to a remote PC.
• The recorder may be set to send complete or partial downloads to a remote PC at any desired interval. The remote PC will need to be ready to receive the data.
• Collecting timed downloads from a remote PC.
• A PC and modem at a remote location can be set to manually or automatically dial a logger and collect a set of readings from it.
• Send an alarm message to a text radio pager or to a mobile phone using text messaging (SMS).

The form of the message will be simple text showing the nature of the alarm call (name of control unit, description of sensor in alarm and its temperature). The person responsible for the equipment can then find a PC and dial in to download a full set of data to judge how serious the alarm may be.
