1 FUNCTION
The detector is designed for detecting fixed tem-
perature or rate-of-rise, forming a 'fire alarm'
notification and transferring the notification to the
Astra-A RPA via Signaling Line Circuit (SLC).
Compatible with Control Panels: Astra–812 Pro or
Astra–8945 Pro (firmware version 4_0 or version
higher).
The detector provides measurement and transmission
via SLC according to Astra-A RPA Extender parame-
ter: ambient temperature (°С).
● Astra–43A is powered by Astra-A RPA Extender.

5 ADDING TO THE SYSTEM
1) Connect the RPA to the Control Panel using RS-
485 interface.
2) Add the Astra-A RPA Extender to the Control
Panel according to the user guide of the panel Astra-812
Pro or the PKM Astra Pro built-in manual.
3) Remove the electronic unit
by turning it counterclockwise
relative to the base.
4) Connect the SLC power
(terminals "+" and "-") and the
SLC interface (terminals "A"
and "B") from the Astra-A RPA
to the terminals on the base.
5) Run the RPA registration
mode according to the user
guide of the panel. It takes
60 sec to register a detector.
6) Run the registration mode
via two possible ways:
- setting the detector on the base (p. 8, a. 5) (power is
on and SLC connected);
