LEDs
The OEM SHC Controller features three LEDs: a green power LED (LED 1), a red alarm LED (LED 2), and a yellow status LED
(LED 3). The various different possible blinking patterns and the corresponding meanings are listed in Table 2.
After power-up, all of the LEDs are illuminated for a short time during a factory self-test.
