OVERVIEW
The AS200TX transmitter
can be used on the AS200 and AS300 alarm and monitoring
systems. The transmitters will alarmand
send data
to the AS200RX, AS300RX and AS300 Communicators. On the
AS300 systemdetails
of an individual transmitter can be viewed on a mobile
phone, recorded to the web and sent to a local PC. This includes alarm
status, i/p1 and i/p2 current temperatures, high alarm,
low alarm, delay time, power status,
transmitter signal strength to receiver and GSM
settings.
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)
I
nput
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 alarmwill
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.
