4120EC Home Security Installation
The VISTA (4120EC) is a microprocessor-based security control which provides up to 8 wired zones of protection. The control is housed in a wall-mounted metal cabinet and can be used with either 4127 or 4137 consoles. The consoles feature a mutifunction 12-key digital keypad and a fixed English language LCD status display. Optionally, a No. 5330 Alpha Console may be used with the control to provide programmable English language zone descriptors and status indications.
Connections to the security control are made via a 25-terminal connector block wich is used to interface to the wired loops, plug-in transformer, telephone line, remote consoles, external alarm sounder(s) etc.
The control can be easily programmed from a remote console or via downloading. Programmed options stablish specific alarm and reporting features are stored in electrically erasable, non-volatile EEROM memory. This means that the unit can be reprogrammed many times (unlike units equipped with PROMS) and that information which has been programmed will not be lost in the even of a complete loss of power.
