Technical Details : there are 4 pack, not 6pack,.
【Photoelectric Technology&Material】: Fire-Retardant ABS V0 Level. 9V Battery-Powered Photoelectric sensor Smoke Alarm. photoelectric technology which is optimized to detect slow smoldering fires which generate light smoke, little heat and may smolder from all directions for hours before bursting into flames..
【Easy Installation】: Can be installed in several minutes. Coming with screws and bracket. Safety clip feature,not allow mounting of smoke alarm without battery installed.
【Sound & LED Warning】: When the fire alarm detects smoke or detect combustion particles in the air it will sound their alarms(Alarm volume: > 85dB(A) @ 3 meters) and the red LED will flash rapidly. The LED light and alarm will continue until the air is cleared or the test button is released..
【Suitable for Multiple Places】: This smoke detector does not contain any radioactive material. It should be installed in every room (except the bathroom and kitchen), making sure the people in your home will be able to hear and respond to the alarm sound..

Transmission Signal---- Variable Resister can simulate the pretend signal of coolant temperature sensor, throttle valve sensor and send thepretend signal to vehicle ECU. It would avoid risk to change the new parts again.
Multi-function---- The automotive test lead kit can be used to monitor Hall Effect, photoelectric signals, nozzles, electromagnetic valve of transmission shift gears and control signals. SRS connector provided can simulate air bag and routed contracting device of safety belt to avoid accident or miss-judgment.
Easy to Use---- When checking the parts, it could connect the back of terminal directly, would not to damage the circuit, reduce thecircuit rust and avoid to adding impedance. When checking the electric current, only use the lines to connect the circuit, do not need to cut the electric wires.
