Three alarm programmable relay output module kit designed for use with the EFM-100 and the LD-250 for high accuracy short range detection, along with coincidence mode for virtually eliminating all false strikes. This Boltek Lightning Kit comes with RLO-10, EFM-100, LD-250 and display software.


The ERL-10 receives data from the EFM-100 Electric Field Mill short-range sensor (<20 miles/32 km) and a LD-250 long range lightning detector. These industrial alarm systems constantly monitor for lightning and activate their timed relay outputs when lightning is detected. Up to three alarms can be configured, referred to as Red, Orange, and Yellow Alert levels. The green All Clear state is entered when no lightning has been detected within the configured time period.

When the Boltek Lightning ERL-10 is first turned on, it enters Survey Mode where it looks for lightning. After several minutes without lightning (configurable but typically 10-20 minutes) the system enters the All Clear state. The green All Clear light on the ERL-10 illuminates and the All Clear relay output activates.

Coincidence Mode
With Coincidence Mode enabled on these industrial alarm systems, a lightning strike must be detected by both the EFM-100 and the LD-250 in order for an alarm to activate. This virtually eliminates false alarms that could be caused by persons, animals, insects, etc. near the EFM-100 sensor. Coincidence Mode is only applicable within the range of the EFM-100 (0-20miles/0-32km).

Status Monitor
The ERL-10 Status Monitor software (included) allows the system status and countdown timers to be displayed. Countdown timers clearly indicate the number of minutes until All Clear. Alarm activations are timestamped and logged to disk. Graphical log file viewing software is also included with these industrial alarm systems.
