Most equipment today does provide some form of alerting signal to interface to
monitoring devices from reporting of various malfunction or abnormalities. There are
various kinds of signal that the equipment can send out, most common of which are
opening or closure of one or more switch relay contact. UPS usually provide signals such
as incoming power fail, battery mode, battery level low, and switchover failure. An air
conditioner system may provide signals such as system on/ off, compressor over
temperature, low gas pressure, etc.
Equipments to be monitored are connected to WT-9001 using these alarm signaling
contacts. WT-9001 keeps a constant watch over all the contacts. Whenever any contact
input changes status (either from a close to open or from an open state to close state) it
is captured by WT-9001. It will then process the input according to the configuration
provided by the user. The correct SMS messages will be sent to 8 mobile phone users.
WT-9001 is so fast in capturing the change of status of any signaling contacts that no
event will be missed out up to 8 inputs can be monitored directly. The flexibility of WT-
9001 is in allowing remote query of input status using SMS.
To change contacting mobile phone number is also very easy. Authorize personal
remotely using SMS command to add, change or delete mobile phone number in WT-
9001.
WT-9001 is a 2 way device. Besides monitoring inputs and act upon such inputs it also
allow mobile phone users to compose SMS messages to it. When WT-9001 receives any
SMS, it will look its memory bank to see what it is supposed to do and action according.
No action SMS are ignored.
Up to 8 relays can turned on and off by messages received from mobile phone. Users
can define individual messages from each relay output. For examples, one can specify a
