Alarm Module T941AM8
T941AM8 has 8 physical inputs for connection to external alarm devices. Inputs are galvanically isolated, have
transient protection, and can be programmed for making or breaking contacts. There are an additional 56
logical inputs that can only be activated by programmed parameters.
A FLASH PROM in T941AM8 enables remote programming of the program and parameters. T941AM8 is
used in teleCOURIER 900, telePROTECT 900, and CTS 900.
T941AM8 is not intended for connection to public telephone networks.
Note:
To facilitate service after the unit is installed,
we recommend a free space of about 50 mm
above and 150 mm below the unit.
