Astra-43A
Addressable heat detector
The detector is designed for detecting fixed temperature 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.
Features
- 4-wire connection;
- powering from Astra-A RPA (24 V DC);
- testing by laser pointer Astra-942;
- transmitting temperature to the control panel via SLC.
