LED activity
The LEDs on the control panel motherboard (refer to Table 2-6: Mother board - description of
parts, K) may help in providing information regarding the proper operating capacity of the
control panel firmware and I-BUS. Specifically:
GREEN VCC LED
Green LED ON solid indicates the power supply is present. If ON solid it indicates that the
control panel is operating properly. LED OFF or blinking indicates power-supply failure or that
trouble is present. The control panel will continue to operate until the deep battery discharge
threshold is reached (9.5V).
BLUE RUN LED
If the control panel is operating properly, the blue LED on the motherboard will blink rapidly.
At the end of a programming session via PC, during restoral of factory default settings and
during re-programming operations on the control panel and peripheral firmware, the LED may
be either On solid or Off or the entire time. However, once the operation is complete it will
start to blink again as previously described.
If the LED is On or Off permanently for no apparent reason (see above), it means that all the
system functions are blocked.
YELLOW BUS LED
If the control panel is operating properly, the yellow LED on the motherboard should flicker. At
the end of a programming session via PC, during restoral of factory default settings and
during re-programming operations on the control panel and peripheral firmware, the LED may
be either On solid or Off or the entire time. However, once the operation is complete it will
start to blink again as previously described.
If the yellow LED is On or Off permanently, it means that there is trouble on the I-BUS.
If the LED is On or Off permanently for no apparent reason (see above), it means that the I-
BUS is blocked. This condition is confirmed by the loss of communication with the keypads,
readers and expansions.
RED PSTN LED
The Red LED ON solid indicates the ongoing progress of:
• a phone call (on the PSTN line or through Nexus)
• an SMS text message
• a SIA-IP communication

ATS Categories
Prime control panels used alone or together with any of the following described optional
devices constitutes an SPT (Supervised Premises Transceiver) which can be used to create an
ATS (Alarm transmission System) as defined in EN 50136-1 and EN 50136-2 standards.
The following table shows the maximum ATS categories achievable with the SPT
configurations and main communication channel in use, together with the respective
parameters.
