Overview - Menvier Security SD1 Operating Instructions Manual

1. Overview

C
Control Panel
Connections: The SD1 is connected between the alarm control panel and the telephone
line. It behaves like another extension to the telephone and does not affect its normal
operation or that of any other extension fitted. However, if the SD1 is operating the messages
will be heard if any handset is lifted. The unit requires no batteries as its power and mains fail
back-up are derived from the alarm control panel.
The SD1 accepts three inputs which in our example are; A - Personal Attack (PA), B - burglary
and C - fire. These correspond to the messages (A, B and C) that the SD1 sends out and
should be recorded as such. If the control panel does not have a fire monitoring capability
then the SD1 will accept a direct connection from a suitable smoke alarm (as above). The
SD1 may also be included in the control panel tamper circuit.
Telephone Numbers: The SD1 will dial up to three different telephone numbers and play its
message. The numbers may be up to 16 digits long and are simply programmed using the
text display and keypad on the unit.
Messages: The SD1 has a built-in microphone and speaker so that phrases can be
recorded and replayed directly from the unit. When the out-going call is answered the SD1
plays a common phrase (0) and one of the three alarm messages (phrases A, B or C).
Phrase 0 states your name and address and phrases A, B and C relate to the inputs from the
control panel (PA, burglary and fire in our example). Each phrase can be up to 8 seconds
long giving a total possible message length of 16 seconds (0 + A, B or C).
Acknowledgement: On receiving a call from the SD1 the person answering acknowledges
it by pressing the number [8] on their telephone*. The SD1 may be programmed to stop dialling
after the first call has been acknowledged or when two or three have been acknowledged, as
required.
If the message is not acknowledged then it is repeated four times after which the dialler
abandons the call. It then dials the next number. This procedure is repeated three times in
sequence for all three telephone numbers. If no acknowledgement has been received
then the dialler shuts down.
* Certain older types of telephone may require a tone dialling simulator to do this.
