4.2 Remote SMS requests
Besides receiving alarm message in remote area, there are others useful SMS functions available for
pre-configured hand phone users.
(1) Alarm Acknowledgement:
To stop SMS alarming from further escalating or reminding, send the acknowledgement SMS to the
gateway. The format is as such: ack xxx. where xxx is the point name given to the alarm point. Upon
receiving the acknowledgement SMS, the gateway makes an announcement to all the hand phone users
who have received corresponding alarm message. These hand phone users will then receive SMS in such
format : <pt#x><xxx>acknowledged by yyy. where xindicates the point number, xxx indicates point
name and yyy is the hand phone number which sent the acknowledgement SMS.
(2) Request the current status of a contact point:
To know the current status of a contact point, send the status request SMS to the gateway. The
format is as such: get xxx. where xxx is the point name given to the contact point. The reply is in such
format: <pt#x><xxx> is open/close <normal/alarm/alarm acknowledged><yhrzmin>. where x
indicates the point number, xxx indicates point name. In the last bracket, <yhrzmin> indicates how long
the contact point has been staying on that state, either open or close.
(3) Trigger the relay output:
SMS alert gateway provides two relay outputs, which are triggered through SMS message. To
trigger one output, send SMS in such format: set xxx 1/0. where xxx indicates the point name, 1for
triggering output into alarm state, and 0to recover that output. If the relay output is connected with
normally open circuitry, then SMS message, set xxx 1 closes the output. Vice versa, the same SMS
opens the output for normally close circuitry. Upon receiving relay triggering message, SMS alert
gateway generates the following reply, <DO#x><xxx> is open/close. where xindicates the point
number, xxx indicates the point name. Power reset will take place if during receiving SMS, the gateway
has its appropriate (xxx) relay output (NC when closing or NO when opening) connecting to power.
(4) Activate\Deactivate a contact point:
Only the hand phone numbers configured as administrators is allowed to either activate or
deactivate a contact point through SMS. The SMS format is as such: act xxx 1/0. where xxx indicates
the point name, 1for activation and 0for deactivation. After deactivating a contact point, SMS alert
gateway does not send any alarm SMS whenever the point is under alarm condition.
(5) Correct the internal clock:
The internal clock of gateway can be corrected by sending SMS in such format: tim. After receiving
the SMS, gateway will synchronize its own internal clock with the actual real time clock according to
