Main features
Triggers
The SD3 has eight trigger inputs and you can assign a voice message and/or a
text message to each input. The unit can also send a voice message and/or a text
message when the triggers have been restored.
For most applications you would normally connect the trigger inputs to the com-
municator outputs (or bell output) of an alarm control panel. However, you can also
connect other devices, such as smoke detectors or temperature sensors directly
to the trigger inputs. The unit allows you to program the polarity of the trigger
inputs as either positive or negative applied/removed.
Contacts
The SD3 allows you to store up to 10 contacts: you can assign each one a name,
telephone number, message type, and acknowledgement type.
IMPORTANT: DO NOT use the SD3 to call the Police via the emergency services
phone numbers.
Voice Messages
The SD3 has a built-in microphone and speaker to allow you to record and replay
audio messages directly from the unit.
The SD3 can store up to eight separate alarm messages, eight restore alarm mes
-
sages (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). Each message can be up to 30 seconds in length.
Text Messages
The SD3 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 cen-
tre, which takes the text message from the SD3 and forwards it to the contact’s
mobile telephone. The unit can store eight separate 40-character alarm messages,
eight 40-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 mes-
sage, it adds the alarm message to the site details message.
Acknowledgement
On receiving a voice message call from the SD3, the contacted person can ac-
knowledge it at any time by pressing 8 on their telephone. If the contact does not
acknowledge the voice message then the SD3 repeats the message several times,
after which the unit abandons the call and dials the next available contact.
Call-Abort
The SD3 has several call-abort options, which include restoring the trigger input or
entering the user code. When the unit has aborted a call it immediately shuts down
and returns to its normal standby mode.
Outputs
The SD3 has four 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 SD3 displays the 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.
Listen-In Mode
The SD3 has a listen-in mode, which switches an internal microphone to the tel-
ephone line so that you can hear activity at the protected site.
The contact can activate the listen-in mode at the time of receiving a voice mes
-
sage or by calling into the SD3 and using the Remote Access feature.
Talkback Mode
The SD3 has a talkback mode, which switches the internal loudspeaker to the tel-
ephone line so that you can talk to the protected site. The contact can activate the
talkback mode at the time of receiving a voice message or by calling into the SD3
and using the Remote Access feature.
Message
The SD3 allows you to record short audio messages, either locally at the unit, or
remotely, using a touch-tone telephone. After recording a new message the unit
will indicate it on the display and can optionally give a beep. You can also program
the message feature to record when a trigger input is activated.
Remote Access
If you enable this feature you can access the SD3 remotely by dialling into the unit
with a touch-tone telephone. Once connected you can turn on and off the four
outputs, activate the listen-in/talkback mode, listen to the message, record a new
message, leave a memo, carry out test triggers or record telephone numbers.
