For those who like to know the technical stuff…

TowerSentry's NOC went through a rigorous two year examination by the Federal Communications Commission to receive expeditious waivers for required Quarterly Tower Light Inspections. Here are just a few of the items TowerSentry® provided to the FCC.

TowerSentry utilizes robust enterprise class servers with triple automatic failover redundancy.

Each server has a mirrored hard drive and dual power supplies. In the event of a hard drive failure, the second hard drive automatically takes over. In the event of a power supply failure, the second power supply automatically comes on line. In the event of a major board failure, the hot standby secondary server automatically takes over. This server has the same full redundancy as the primary server. In the event the secondary server fails (highly unlikely), a third backup server takes over.

Each server power supply (six total) is supported by separate uninterruptible power supplies. An onsite backup generator provides power to our facilities in the event of a utility power failure.

Signals from your tower site are delivered to TowerSentry's NOC through multiple paths. Triple redundant Internet connection is provided by three independent sources: Direct Satellite, Cable, and DSL. Automatic signal failover is provided by copper Telco pots lines.

Digital alarm receivers accept signals from your tower site. These signals are processed by the servers, prioritized and displayed at multiple workstations staffed by trained personnel. NOTAMs are issued and tracked in full compliance with FCC rules and regulations.

Unlike monitoring systems that "Poll" data from your tower site once per day, TowerSentry's TSMS© actively monitors your system. Each tower site transmits a minimum of three signals per day providing the mode of operation (lights on, lights off/ day mode, night mode) along with a daily self-diagnostic test signal (providing radio signal strength in dbm).

Every tower site monitored is expected to report. In the event that a signal is not delivered, an alarm is brought to the attention of our monitoring technicians identifying that site.
