[1]Devices, such as local sounders and beacons can demand high inrush currents, which may
damage the relays. If relays are used to drive the device directly, a suitable 47

Ω

current-limiting

resistor should be placed in series with the load.

Features

The following is a list of major features of the EX detector:

• Patented “artificial intelligence” known as ClassiFire (automatically learns

environment)

•  Laser dust discrimination (LDD)
•  Quick and easy installation
•  Self-adjusting between the range of 0.4% and 2.0% obscuration
•  Pre-engineered sampling pipe network designs
