What is a Four Wire Smoke Detector?The 4 wire smoke detector (2 wires for the zone alarms and 2 wires for the power) is still describing the type of detector but the extra Form-C relay contacts are an added "with an auxiliary relay" to the description of the 4-wire smoke detector.
Types of Fire Alarm Systems and Their Wiring DiagramsA smoke or heat detector can be installed to the existing or new home wiring. in our basic wiring diagram, a single or multiple heat and smoke detectors are installed in the home by connecting the live (line or hot), neutral, ground and an interconnected wire to the alarm.
What is a 4 Wire Smoke Detector? By Douglas Krantz. Even though it uses an internal protection resistor and internal alarm relay contacts, a 4 wire smoke detector is basically a 2 wire smoke detector; it detects smoke and sends an alarm using the Class A or B zone wiring of the fire alarm system.
How Do I Know Whether to Use 2This is necessary for resetting the smoke detector. Both 2-wire and 4-wire smoke detectors must be powered down to reset. But the process for accomplishing this differs greatly between the two different types of smokes. This factor is ultimately why most DIY users select 2-wire smokes over 4-wire smokes.
