1.4 The keypad is powered from external DC redundant power supply units with
nominal voltage 12 V or 24V.
1.5 The keypad has two independent power supply inputs (main and auxiliary).
Switching between them occurs automatically when voltage is below the acceptable level
according to GOSTR 53325.
1.6 The keypad has an input controlling consolidated signal “Failure” from power
sources (terminals Zone1, GND).
Note –The input Zone1 is not intended for connection of any detectors or their
power sources across the alarm loop.
