displays the sensitivity of i3 detectors in terms of percent-per-foot obscuration

or control of HVAC components

or other strategic locations

This fall in the impedance of the detector is recognised by the control panel as an alarm signal

Faraday 8702 27/11 displays the sensitivity of i3The Faraday 8702 is an addressable contact device interface module designed to integrate dry contacts (normally open or closed) into the addressable device circuitry of a fire alarm system. It only monitors and reports the status of the contact inputunlike the 8704, which includes an addressable Form C relay. Features and operation include: Multicolor LED indicator on the front plate, which signals: Red for alarm, Yellow for trouble, Green for normal
