LABORATORY MONITORING SYSTEMS

The Sigma Delta Technologies Laboratory Alarm and Monitoring System (LMS) has been designed to cater for all types of laboratories. It enables a laboratory to monitor all it's critical instruments whether there are spare alarm lines available or not. It can be integrated with existing alarm systems without using excess line capacity. It can be built up to handle any number of instruments. It can perform alarming only or do continuous monitoring and logging of vital instrument parameters.

In its basic configuration it consists of two modules. The first is the  Input Sensor Module (ISM). This is a input module combined with an intelligent radio transceiver which is attached to each instrument that is to be monitored. It is battery or mains operated and the battery condition is constantly monitored, and alarmed if low. The sensor module has 2 temperature inputs which can range from -196 degrees Centigrade to +50 degrees Centigrade; two analogue inputs with variable voltage input(0-100mV, 0-1V) and two digital inputs).

The radio transmitter is 433.92MHz and has a nominal range of 120 metres outdoors and 30 metres indoors. The effective throughput is 4800 baud. The ISM is continuously monitored for fault conditions and alarmed in this event.

The other module is the Central Monitoring Unit (CMU). This is the master which controls the whole system. It has an identical transceiver as the ISM. The CMU can be stand-alone or combined with a PC to make it more flexible. The CMU initiates scans of all ISM’s, downloads alarm levels to all ISM’s, stores data until printed out or transferred to the PC and provides alarm outputs for strobe, siren and a NO/NC output. The storage capacity of the CMU is 2Mbits. There is a 4 x 4 keypad and 1 line x 16 character LCD display. The system is programmed via the keypad and all parameters downloaded to the respective ISM’s. The system is powered by a mains plug pack providing 12 volts. An optional transceiver may also be provided to act as a relay link in the event of distances being in excess of the 30 metres.
An optional telephone dialer with pre-recorded messages is also available. This provides remote fault indication to for up to six telephone numbers. The system can be integrated into hospitable systems via the NO/NC output.

To monitor your laboratory, just decide what you require to monitor,how you wish to be notified of an alarm and contact Sigma Delta Technologies for a price.

INPUT SENSOR MODULES:
These can be fitted to suit incubators, liquid nitrogen tanks, gas bottles, automatic changeover systems  for gas bottles, refrigerators, freezers, etc. If you have an instrument that you wish covered and are in doubt about it, contact Sigma Delta Technologies to discuss it. Humidity sensors may be attached.

FEATURES:
- a wire-less system with no cables to get in the way. Instruments can be readily moved
   without any rewiring.
- A system that can be readily expanded to suit any Laboratory. It is totally modular.
- Easy to install.
- An ISM to suit most requirements.
- Battery back-up for power failures.
- You monitor only those instruments of concern to you.
- Battery monitoring and alarming.
- Sensor monitoring and alarming.
