TEMPERATUR - CONTROL

• Alarm supervision. 10 analog inputs for temperature sensors + one for outdoor temperature
• High and low temperature alarm + alarm by unacceptable alterations
• Unwanted alarms caused by high outside temperature can be avoided safely.
• RS 485-interface
• Local alarm (siren) and function for alarm calls can be activated individually on each input

Survey

• Display shows temperatures
• All operations are done on the keyboard. You avoid thermostats in each room which need adjustment.
• Historical function: You can go back in time and see temperatures and alarms with indication of date and time. Function for seeking on lowest and highest value.
• Available with Speech Processor which among other things can:
  • make alarm calls on telephone and describe in proper words the cause of the alarm.
  • by pressing one key on the keyboard you can have status and alarm description, if any, in clear speech.

Alarms

• Alarm for high and low temperature.
• The alarm can be triggered if the temperature changes more than allowed. Comparisons are continuously made 10 minutes back.
• Local alarm (siren) and function for alarm calls can be activated individually on each input
• The initiating of alarm calls can be set to be delayed from 1 to 9 minutes.
• Lightning/transient protection.
• Filter for short (insignificant) alarms.
• You can avoid unwanted alarms in hot weather by entering a summer increase = number of degrees Celcius by which the indoor temperature is allowed to exceed the outdoor temperature.

Safety

• Alarm for defects - short circuits and broken cables - at all inputs.
• Alarm at too low voltage in power supply.
• Temperature sensors and keyboard housing are IP 65.
• Possibility for automatic test of accumulator every day at 0800 hrs.

Communication

RS232 and RS485 interface are integrated. Communication opens up for many possibilities which you will soon appreciate.

• Communication with a PC and Professor Partyline for presentation of trends of the temperature. Remote control - for example setting of alarm limits and toggle active/idle mode of each input. This can also be done through telephone by means of a modem.
• By means of a Speech Processor Dr.Bell inquiries and operation can also be done through telephone.

Expansion Possibilities

• Can be expanded by more units connected in network.
• Temperature ranging from -40,0 to +40,0 degrees C. and from -40,0 to +120,0 degrees C.
• Supervision of O2 and pH-value.

Extension by an ALARM-UNIT serving 8 ON/OFF inputs and 4 outputs.
