Table 6. READY LED Behavior in Different Signal-10 Operating Modes
№ Operating mode LED Behavior
1 Pre-Operation Mode OFF
2 Operation Mode Lit with green
3 Master/User Key Programming Mode Double flashes with green every second
4 Power Failure Mode Flashes yellow once per second
5 Self-Diagnostic Mode Flashes red twice per second
6 Device Failure Mode Flashes red four times per second
7 Output Circuit Failure Mode Flashes red once per second
Pre-Operation Mode
When supply voltage is applied to power terminals, the device activates and switches to the Pre-
Operation Mode. The device power-up time doesn’t exceed 3 seconds provided that 11V or higher is
available at least at one power input.
Operation Mode
After the Pre-Operation Mode the device switches to the Operation Mode. In the Operation Mode the
device provides its main functions, those are alarm loop monitoring, fire alarming, trouble monitoring,
built-in relay performance monitoring and control. When used together with the Orion network control-
ler, the Signal-10 also communicates data with the network controller.
Please note, that the device sounds with a melody and the READY LED is switched on with green to
enable user to easily recognize that the device has successfully switched to the Operation Mode.
