Maintenance Check Recommendations
A maintenance check should be conducted every 3 months, if a communications error is displayed or
if the system is suspected of not recording obvious lightning events.
Sensors and Range Extenders
• Check for physical damage to exterior of Assembly.
• Check for physical damage to Cables (Power and Siren cables).
• For Sensors check for damage to electric field sensing needle at top of sensing antenna.
If damaged (bent) or missing please contact local LPI distributor for an approved replacement.
• For Sensors check that earth rod is still installed correctly and earth cable from Sensor is still
connected.
• Check condition of Fuse (Package A: inside power supply enclosure, Package B: inside battery
box).
• Disconnect and reconnect power to the Sensor/Range Extender.
Console
• Check Red power LED is on.
• Check that Communications Antenna has line of sight to the nearest Sensor or Range Extender.
• Check that the Ethernet Cable is correctly inserted in the Console Ethernet socket, and that the
Ethernet cable is still connected to a computer or network switch at the other end.
• Check that the green network lights are on, they indicate that the network cable is actually
connected to a network.
• In settings page re-confirm settings (e.g. System Time, Indication Duration, All Clear Time-out
Period and Alarm Enable Times).
• Test Alarm Sounding Operation (in Alarm Override page). Ensure that all personnel are aware of
imminent test before hand, to avoid unnecessary confusion.
