READ THE COMPLETE MANUAL BEFORE ATTEMPTING INSTALLATION AND ACTIVATING
THE SYSTEM.
1. DESCRIPTION
The telephone interface 450-00064 is used to switch an electrical device and can send
2 alarm messages via the telephone network. Each of the two alarm inputs can choose 3
telephone numbers and leave a speech message if an alarm input is activated by a connected
contact. Both alarm inputs can be activated and deactivated separately.
Switching is carried out via DTMF signals (DTMF= Dual-Tone Multi-Frequency). This can
easily be set via a call to the telephone interface. You can choose the feedback language
yourself.
The interface can be built into a DIN rail cabinet (4U). The switch functions can be carried
out via a call, an external push button or via a flush mounted push button (see fig. 1). The
telephone interface is protected by a 4-digit code. The settings and switch statusses of the
outputs are saved during a power failure and are retrieved once the power is restored. If
you wish the interface to remain active during a power failure, you can permanently connect
it to a backup power supply of 12VDC.
