Text Messages:
The SD2 can also send text messages to mobile telephones using the SMS
text service (Short Message Service). The unit does this by calling a SMS
service centre, which takes the text message from the SD2 and forwards it
to the contact's mobile telephone. The unit can store up to four separate
32-character alarm messages, four 32-character restore alarm messages
(a different message can be sent when the trigger event has been
removed) and one common message (normally used to store the name and
address of the premises). When the unit sends a text message, it adds the
alarm message to the site details message.
The site details message would normally hold the name or details of the
premises being protected.
Acknowledgement:
On receiving a voice message call from the SD2 the contact person
answering the call can acknowledge it at any time by pressing 8 on their
telephone. If contact does not acknowledge the voice message then the
SD2 repeats the message four times, after which the unit abandons the call
and dials the next available contact.
Call-Abort:
The SD2 has several call-abort options, which include restoring the trigger
input or entering the operator’s passcode. When the unit has aborted a call
it immediately shuts down and returns to its normal standby mode.
Outputs:
The SD2 has programmable outputs that you can use to indicate the status
of the unit. You may also program the outputs for remote control. For
example, you could use this facility to remotely turn outputs on and off
with a touch-tone telephone.
Temperature sensor:
The unit can display current ambient temperature. You can program
temperature high and low alarms, linking them to two corresponding
output types.
Time and date:
The unit contains an internal clock which can display the current time and
date. In addition, the time and date will be added to text messages and
trigger events thus providing a useful audit trial in the log.
Please note that the time and date feature is designed as a guide.
