How Do I Set Up A Honeywell Wireless Flood Sensor?
The Honeywell 5821 is a Wireless Temperature Sensor and or Flood Detector. The Honeywell 5821 Flood Detector can be a stand alone flood detector or it can be monitored remotely when paired with a Honeywell 470PB probe and the included resistor. The 5821 Flood Detector will send an alarm via the RF transmitter to the control panel when a flood is detected. A separate 5821 is required for each external probe being used.
To set up the operating mode for the 5821/470PB Flood Detector the Loop and Dip switch must be set up. To use the 5821 to monitor two different condition, each loop must be programmed as its own zone. Set the Dip Switch to SW2=On, Loop 3. The sensor will fault when the external probe tip (470PB) is in contact with water for less then three minutes. The sensor will restore when the probe tip has not been in contact with water for less then three minutes. Once the operating mode has been set up, the 5821 needs to be enrolled to the control panel. Enter the control panel’s programming mode and enter the zone number to be programmed. Enter the zone type 24-HR Aux, Waterflow. Enter Input Type 03 (supervised RF transmitter). When prompted for the serial number, press the tamper switch on the 5821 transmitter. Once the serial number is displayed press the tamper switch again. Loop number 4 will begin to flash, Manually change the loop number to 3. Exit the programming mode.
When the 5821 is used with either external probe, an open-circuit or a short-circuit of the probe’s wiring results in an alarm on that loop, and a trouble condition on all other programmed loops.
For the best signal strength when using the 5821 flood detector with a 470PB flood sensor probe, use no more than 48 inches of wire from the 5821 to the flood sensor and connect the termination resistor across the probes terminals.
