This page explains the JEMRF Wireless Switch Sensor
The Wireless Switch Sensor can sense the opening or closing of a tactile switch. Usually used for door window sensing for alarm system, but is also the foundation for other sensors like water sensor and motion sensor.
Install battery and close enclosure as described here.
Thread the antennae through the the case enclosure and push the sensor into place within the enclose
- Close the enclosure case using a Phillips screw driver
- See the testing section of this documentation
- Powered by CR2032 coin cell battery
- Can be externally powered by soldering to the 3V3 and GND through holes on the PCB
- Most energy efficient when the BTN contacts are not connected, therefore use a normally closed switch to monitor a door/window that is normally closed and a normally open switch to monitor a door/window that is normally open
- Tested at 288 (144 door open/door close) messages per day for 1 year on one battery
- Standard JemRF wireless sensor, refer RF Communications section for all the details
- Highly configurable
- Opening or closing the switch will cause the device to come out of sleep mode, transmit a reading and then go back to sleep
- For Flex modules use Pin 6 and Pin 10 to connect to the external switch
- BUTTONON- (sent when the switch is open)
- BUTTONOFF (sent when the switch is closed)
- STATEON- (the switch state is sent every INYVL minutes if the switch is open)
- STATEOFF (the switch state is sent every INTVL minutes if the switch is closed)
- BUTTON (the BUTTON command requests the the switch state from the sensor)
Note: On power up of a wireless switch, do not open/close the switch during the first 5 seconds as this will cause the device to start sending messages and cancel the startup sequence and prevent the device from entering sleep mode.
- 36mm x 36mm x 15mm case size (1.42” x 1.42” x .59”)
- Type 1 (Type 1 sensor)
- NOMSG3 (Sends 3 switch readings every time the switch state changes)
- INTVL030 (Sends the switch state every 30 minutes)
- SLEEP (puts the device into sleep mode)
- Refer device configuration for more details
Note: Did you know this sensor is also a multi function sensor?
