Wireless LCD keypad for PERFECTA 64 M control panels

PRF-LCD-A2 is a wireless keypad designed for daily operation of the PERFECTA 64 M control panels operating together with one of the ABAX 2 system controllers: ACU-220 or ACU-280. Two-way encrypted radio communication with the controller takes place at 868 MHz frequency band. Large keys, an LCD display and LEDs indicating system status make operating the system convenient and clear. Apart from the number keys, the keypad also features keys for quick activation of the selected arming mode (day, night, full) and triggering three alarms: Panic, Fire, Aux.

The PRF-LCD-A2 is fitted with a built-in reader of proximity cards and tags used for operating the alarm system. These may be used to switch on the full alarm mode, disarm the system or clear the alarm as well as to control devices connected to the alarm system outputs.

The main keypad’s power supply consists of two CR123A 3V batteries. Their condition is continuously monitored. The device operates in either wake-up or sleep mode (to save energy in case of inactivity). It is possible to further reduce power consumption by switching off the proximity card reader. The keypad can be provided with external power by connecting it to a 5 V DC power supply, e.g. APS-055. When the keypad is in the wake-up mode, it works in much the same way as the wired LCD keypad – the display is always on. In this mode, the batteries are only used if the external power supply is interrupted.
