Part # - 5002-09-MD - Point Sensor Magnetic Door, 433 MHz
The Point Sensor Magnetic Door wireless transmitter is a battery operated digital counter sensor with a microprocessor controlled 418 MHz or 433MHz. FCC certified radio transmitter. The Point Sensor Magnetic Door has an on board time of day clock that allows it to spend most of the time in a low power quiescent state. At predetermined time intervals the clock will wake up the on board microprocessor. Unique serial number information is read from a Dallas Semiconductor 1-wire digital device, counter data is read from a 24-bit internal counter register. This information is combined with a CRC-16 error check and transmitted in a very short data packet that results in a transmitter on time of only 15 milliseconds. This architecture allows the Point Sensor Magnetic Door to consume very little energy and a battery life of 2 to 5 years results.
The Point Sensor Magnetic Door electronics are coated with a conformal material which provides a moisture barrier against condensation. Submersion in water is not recommended. A push button switch in the ABS cover allows the user to activate the service mode. The service switch has three functions: 1) The Point Sensor Magnetic Door is shipped with the transmitter turned off, anytime the Point Sensor Magnetic Door is to be shipped the transmitter should be turned off or placed in a shielded container to prevent interference. Start the Point Sensor Magnetic Door by a momentarily push of the service switch (you will feel the button click) the Point Sensor Magnetic Door is started. 2) The service switch is used as an aid to installation, when the service switch is pushed a data transmission occurs immediately and a special mark is introduced in the ID field of the transmitted data packet to indicate which sensor is in service or installation. 3) The service switch is used to put the Point Sensor Magnetic Door in a quiescent mode (no transmissions and very low power consumption), this is the state the Point Sensor Magnetic Door is in when you receive it from the manufacturer. Push and hold the service switch for 5 seconds or more to enter this powered down state.
