AS200TX Transmitter

OVERVIEW
 
The AS200TX transmitter can be used on the AS200 and AS300 alarm and monitoring systems. The transmitters will alarm and send data to the AS200RX or AS300RX receivers.  In the event of an alarm activation at the transmitter, it will display the alarm input and the audible alarm will be activated. The AS200RX receiver displays both the unit number and input of the transmitter in the alarm condition; these details will be time and date stamped. Any communications equipment attached to the receiver will be activated immediately or after a programmable window of 10 minutes.

SIMPLE INSTALLATION

It’s easy to install the AS200TX transmitter, first attach the transmitter to the item to be monitored with the supplied bracket and industrial strength Velcro. Secondly fit the probes into the equipment to be monitored.  The unit is now ready to be switched on.

INPUTS

Up to three inputs are available on the transmitter.  A common configuration would be to use input 1 to monitor the air temperature of the equipment, input 2 to monitor the sample temperature and input 3 to monitor the door open / closed condition.  This configuration of the inputs will give maximum protection and temperature data for the sample will be recorded as well as the air temperature if logging is employed on the system.

Input 1 : This is for temperature and the value can be displayed on the transmitter.  This input sends its temperature value to the receiver so it can be monitored and logged if required.

Input 2 : This is for temperature.  This input sends its temperature value to the receiver so it can be monitored and logged if required. (This input is an option)

Input 3 : This is a volt free contact, normally closed in the OK condition and normally open in the alarm condition. (This input is an option)

ALARMS

Once an alarm is activated at the transmitter it will display which input is in alarm and the sounder will be activated. The AS300RX receiver will display both the unit number and input of the transmitter alarming; these details will be time and date stamped. An alarm message including current temperature will be sent to the programmed telephone numbers.  Two telephone numbers per transmitter are available.  On the AS200RX the alarm will display both the unit number and input of the transmitter alarming; these details will be time and date stamped. Any communications equipment attached to the AS200RX receiver will be activated immediately or after a programmable window of 10 minutes.

HIGH & LOW ALARMS

A single high and low alarm can be set for I/P1 and I/P2, these parameters can easily be displayed.

POWER FAILURE ALARM

If power failure is detected for longer than 10 minutes the transmitter will activate a power failure alarm at the transmitter and receiver.

DELAY TIME

A single delay time can be set for I/P 1 and I/P 2 ranging from 0 to 90 minutes, these parameters can easily be displayed.  Input 3 has a fixed delay time of 10 minutes.

TEMPERATURE RANGE

The temperature range of the transmitter is –200°C to +100°C with an accuracy of 0.1°C across the entire range.  This makes the transmitter suitable for many types of equipment from LN2 to incubators.

FRONT PANEL DISPLAY

The front panel display can be used to show the unit number of the transmitter or time delay or temperature of input 1.  When in an alarm condition the display toggles between alarm I/P and variable selected.  The status led indicates the current condition of the transmitter and the alarm active led flashes brightly in an alarm condition.

CALIBRATION

The temperature transmitter has been designed to have an easy calibration procedure.  The transmitter display will show a calibration reminder automatically which is customer enabled, the reminder can be set for intervals of 6 or 12 months or be disabled.  Traceable calibration for temperature can be carried out for the AS200TX alarm transmitters. 

AS200TX TEST TEMPERATURE FOB

 

Test temperatures at +50.0°C, 0.0°C and  -50.0°C can be simulated on the transmitter input 1 to test the alarm.  The fob temperature simulator is attached to a connector inside the transmitter unit and a temperature probe bypass switch is thrown.  The simulated temperature is selected and will be shown on the display.  If this temperature is out with the alarm limits it will activate the relevant alarm after the time delay.
