24R [M]
Reset able auxiliary power supply to devices
that operate at 24 V (0.5A max) (powered by the
standby batteries):
ØPositive (27.6 V) on terminal [24R];
ØNegative on terminal [M].

This power supply is disconnected during the reset
of the Control Panel (about 2 s) so it is suitable for
devices that are restored when power supply is di-
sconnected.
