AIM-4SL Start up LED Function
2.4.2 Normal Operation
After initialization and self tests, the LEDs will switch to normal operation and will display information about
the panel operation.
Heartbeat (D14)
—Shows a constant ‘heartbeat’ (0.2 sec ON, 0.8 sec OFF) to indicate proper operation of
the panel and firmware.
Port Status (D15)
—Shows activity on the serial port. Normal activity on the ports will be observed as the
LED blinks many times a second or lighted solid, depending on the amount of activity.
2.5 Firmware
The operating program for the AIM-4SL is stored in re-programmable flash memory. In the event that the
firmware must be re-installed or updated, no chips need to be replaced on the panel. The new program can
be loaded from the host via special software. For normal operation it is not necessary to update the
firmware. If this becomes necessary, contact your Apollo support representative. Firmware updating should
only be done under the recommendation and guidance of your Apollo technical support representative.
2.6 Memory Backup
The AIM-4SL is equipped with on-board memory to store configuration information and event data. This
memory, as well as the real-time clock, is provided with back-up power (for up to 5 days) in the event of
primary power failure. Power is supplied by a special capacitor-based circuit. Battery replacement is never
required.
