The Spyder EL has been designed to meet all requirements for installation under EN50131 and is suitable for use at Grade 3 / Environmental Class II.

The Spyder EL+C has been designed primarily for use in Europe and features an integrated Magnetic Contact; this unit is also rated at Environmental Class II. Operating Modes (Set using on board jumper links)

SET/UNSET Operation

The Spyder may be controlled by the SET output from a control panel thereby enabling automatic reset of any previously detected and latched alarm conditions. In installations where the SET input is not used, the Spyder will behave as a normal non-latched detector.

Latch operation

When selected, the Spyder will display a flashing LED if a valid alarm event has been detected since the previous UNSET to SET transition. The LED will continue to display the alarm event, even when the alarm relay output has closed after the shock has terminated.

Discrete Mode

When selected, the Spyder LED will remain off even under conditions of a valid alarm event.

Sustain Mode

When selected, the Spyder will only signal a valid alarm event when it has detected a sustained series of vibrations. This improves tolerance to normal shock events that are not valid alarms, for example bird impacts.

Sensitivity Ranges

A high or low sensitivity range may be selected to enable the Spyder to be used in a wide range of installations each having their own peculiar vibration transmission characteristics. Within each range, the on-board pot enables continuously variable selection of sensitivity within that range. The pot provides a simple visual indication to the installation engineer of the sensitivity selected.

Multi-unit Synchronisation Mode

Using the multi-unit synchronisation feature of the Sypder, an array of detectors connected together with their alarm outputs in series have the facility to indicate the first unit that has detected the alarm event. In this instance the first unit triggered will show a flashing LED, with all other subsequently triggered units showing an alarm event with a steady LED.
