LiftMaster Photoelectric & Thermal Smoke Detector (4 Wires) | LIF-LMPDT24-4W Doorking Spike Components This is a Push Button

This is a Push Button Door Control

It can take 12/24V solar panels up to 80 watts

The device consists of a high-pressure reservoir which

the e-Loop's 3-axis sensor auto-calibrates at 8 Hz to filter out static interference from rebar and power lines

Integrated XLED antenna allows for compatibility with 433Mhz and 868 Mhz frequency receivers

LiftMaster Photoelectric & Thermal Smoke Detector (4 Wires) | LIF-LMPDT24-4W Doorking Spike Components This is a Push ButtonLiftMaster Photoelectric & Thermal Smoke Detector (4 Wires) LIF LMPDT24 4W The LMPDT24 4W incorporates a state of the art optical sensing chamber and an advanced microprocessor. The microprocessor allows the detector to automatically adjust its sensitivity back to the factory setting when it becomes more sensitive due to contaminants settling in its chamber. Also known as: LM4WT B
