Esser IQ8Quad OTblue multisensor detector, self-test, with isolator, EN 54-5/7/17

IQ8Quad OTblue Self-Test is an addressable detector with optical and heat sensors for ESSER fire alarm control panels. It tests itself: patented technology applies a small amount of test aerosol and heat inside the detector and physically checks both the optical and the heat sensor. Anti-masking automatically checks that the smoke inlets and outlets are clear.

Key features

• Automatic self-test of the optical and heat sensors
• Anti-masking detects covered detectors
• Testing across several panels and loops at once
• Bluetooth to locate the detector, one-person inspection with the CLSS app
• Built-in loop isolator, tolerant to short circuit and interruption
