POL-ESSER is a hand tool designed for checking and detecting faults in ESSER by Honeywell analogue loop installations. 

POL-ESSER is compatible with esserbus® or esserbus Plus® loop devices which can be read from any point of the installation, both in loops which have been already configured and in loops with new devices.

This tool allowed devices acknowledgement  (regardless of the type of wiring), fault detection and site certification.

Backlight 320x240 pixel display shows all the information clearly. The display shows the configuration of sensors and modules, information about the type of device, total and subtotals of polled devices.

POL-ESSER can also read device EPROM in order to see manufacturing date, version, number of alarms and types of fault such as dirty chamber, short-circuits, etc.
