Satel MST-1 Manual

The module DTMF MST-1 is an electronic device that enables the control of an alarm system control
panel by a telephone set that is equipped with the tone dialling mode (DTMF). It allows to check the
status of an alarm system and control panel's zones and to perform certain user functions. It can interfa-
ce with the CA-6 plus (software version 3.04, 4.00 or later) and CA-10 control panels (from the software
version 4.2).

CONNECTION DESCRIPTION

CONNECTOR TO THE
SOCKET OF THE VOICE
SYNYHESIZER SM-2 ON THE
CONTROL PANEL'S BOARD
FOR THE KEYPAD BUS
The module may be installed in the control panel housing.
Plug the connector with cable to the voice synthesiser socket on the control panel's board. If a voice
synthesiser has been already connected to that socket it should be unplugged and reconnected to the
identical socket on the module's board.
Two leads DATA and CLK (without connector) are to be used for the connection of the module with
keypads' buses. Names of the leads indicate the terminals on the control panel's board, to which they
need to be connected. In the CA-10 plus control panel the lead CLK is to be connected to the terminal
CLK1 that relates to the first partition.

ACTIVATION

Co-operation of the module with the control panel requires activation of the options by means of service

functions.

1. FS 5 option 3 in the first set - "Telephone answering".
2. For CA-6 plus:
For CA-10 plus: FS 131 option 2 - "DTMF module operation enabled".
The method of answering telephone is defined in an identical way as for other dialler's functions (single
or double calling, number of rings).
FUNCTIONS
The remote control can be effected from a telephone the control panel calls up during voice messaging
(immediately after the message from speech synthesizer is reproduced), or after getting through from
any telephone set (NOTE! The CA-10 plus v4.2 performs control only when the connection is initialized
from an external telephone set). Having received the call, the module reports its readiness with two
beeps (high-pitched and low-pitched) when it works with the CA-6 plus, or with three beeps (high-
pitched, low-pitched and high-pitched) when it works with the CA-10 plus control panel.
It is possible to perform operations of two types:
1. Checking the status of zones or partitions.
2. Performing a user function.
