1 FUNCTION
• Addressable Mark Astra-MA (further
Astra-MA
) is
designed to receive notifications
via two program-
mable
alarm loops (AL) from non-addressable devices
with a “dry contact” output and to transmit notifications
via Signaling Line Circuit (SLC) through Astra-A RPA
(RPA) into Astra-812 Pro or Astra-8945 Pro (version
5_0 and above) Control Panels.
•
Astra-MA
does not provide connection of detectors
with loop power supply.
•
Astra-MA
provides programming of AL from the PKM
Astra Pro.
•
Astra-MA
provides monitoring of the operability of a
fire-type AL for open and short circuit.
• Astra-MA is powered from the RPA through the SLC
power circuit.
