4. Operating and Testing the Detector
4.1 Initial Power-Up
Before powering-up a SafeFlame detector inspect all aspects of the installed
equipment. This initial inspection can help to prevent future down time and improve the
longevity and performance of the detectors.

-All output, “Normal” signal (N.C.: Energized)
- Yellow LED blinking (0.5Hz)
- Fault Relay signal Closed (N.C.: De-Energized)
- LED “Fault” signal output
- 0-20mA “Fault” signal
- RS-485 communication “Fault” signal
4.2 Safety Handling
Below are a few safety considerations to take into account when the SafeFlame has
power connected.
Ÿ
Please refer to the diagrams and specifications in the user manual
Ÿ
Do not open the SafeFlame while the power is connected
Ÿ
Disassembly and assembly of the internal electrical parts is not allowed by anyone
except the manufacturer. Unauthorized action will void the warranty
Ÿ
Before working on any equipment be sure that the detector is disconnected from
any suppression or extinguishing systems.
Setting Communication Baud Rate
The detector can change the RS-485 communication baud rate. If communication is
not available (SW3-2 is OFF), the baud rate setting is not applicable. After changing the
baud rate, the detector must be reset before using the communication.
