Zeta SP-252/M Simplicity Plus 252 Analogue Addressable Fire Alarm Panel – 2 Loop, 252 Devices (Metal Enclosure) The Simplicity Plus is the ideal introduction to the world of addressable fire alarm panels. As its name suggests, it has been designed with ease of use in mind, using pre-programmed values for its programming options. The installer simply needs to configure the loop and enter text labels via the built-in keypad (optional). The Simplicity Plus has user definable zones, option for zonal or common alarm operation, options for I/O operation, alarm verification and user selectable languages. It can be connected to an RS232 desktop printer for real time event log printing (Epson LQ300+ recommended) and it can also drive a serial repeater model SP/REP (Part No. 37-179).
