The Pertronic F100A LCD Mimic allows remote display of messages from a F100A panel. The Pertronic F100A LCD Mimic can perform all the keyboard-display functions of the F100A panel. Up to 8 addressable F100A LCD Mimics may be connected to a F100A panel and operate in ‘Full Duplex’ mode. More F100A LCD Mimics may be connected in ‘Slave Mode’ - system messages are displayed but no command interaction is available, except for silencing the in-built buzzer.
