Installation and Operation Manual
MODULE DESCRIPTIONS
1.
Power Supply
- Converts the electrical main’s power to +12v (13v - 14v nominal) required to operate the collector
electronics. The power supply also charges the 12v backup battery and maintains a float charge to ensure the battery
is fully charged in the event of a power outage.
2.
Backup Battery
– Is used to run the collector in the event of a power outage. The battery is a 12v, lead-acid type and
can operate the collector up to 20 hours under normal conditions. Run-time will be less in colder conditions or if the
battery is at the end of its life span (approximately 4 years). For optimum results, the battery should be replaced every
4 years or sooner.
3.
AC Circuit Breaker
– A 15Amp circuit breaker is included to protect against over-current faults on the AC power mains.
Used with the Battery Breaker, it may also be used to switch off the power to the collector electronics. Switch off both
breakers to ensure power is removed from the collector electronics.
4. DC Circuit Breaker
– A 15Amp circuit breaker is included to protect against over-current faults on the battery power
supply. Used with the AC Circuit Breaker -it may also be used to switch off the power to the collector electronics.
Switch off both breakers to ensure power is removed from the collector electronics.
5.
Gateway Assembly
– Performs many functions within the collector. Its functions include:
• Receiving and sending messages to the population of installed nodes
• Processing and aggregating data from nodes to be sent to the host server
• Monitoring functional health of the collector modules
• Providing status indicators
6.
Cellular Modem
- Transfers data between the gateway and the server / host system via the cellular / internet network.
7.
Ethernet Jack
- Provides an Ethernet link to transfer the gateway data to / from the server / host system (in place of the
cellular modem).
8.
Antenna Surge Protectors
- Included to protect the collector from nearby lighting strikes.
9.
Power Surge Arrestor
- Included to protect the collector from nearby lighting strikes.
10.
Power Terminals
- Provided to allow connection of the collector to the AC main’s power source.
