Benefits
Always keeping an eye on things
With its extensive optical range and high immunity to false alarms, the SharpEye™ 20/20 MPI IR3 compact mini
flame detector provides reliable area monitoring. It is designed specifically for use in interior spaces with no
explosion hazard.
Reliable protection against fire – and against false alarms
The high immunity to false alarms of the flame detector protects against the negative consequences of false
alarms. At the same time, the installed IR sensors are characterised by a fast response time – allowing the
SharpEye™ 20/20 MPI IR3 to trigger an alarm quickly in case of fire.
Full performance, yet small and compact
Despite the lightweight, energy-conserving design, this compact version does everything you expect from a
powerful IR3 flame detector: A detection distance of up to 43 metres (141 ft) and a wide field of view of 100°
horizontally and 90° vertically.
Available in two output versions
You have a choice of two models with regard to the output options: The version with an alarm and fault relay
(four-wire) and the version with a 4 to 20 mA current interface (stepped) (three-wire). The 20/20 MPI is also
compatible with a RS485 Modbus system for data transmission. The integrated test circuit (BIT – Built-In-Test)
supports both automatic and manual test runs.The SharpEye™ 20/20 MPI IR3 | 03
