Application Note
Room Alert
The Wireless Sensor Hub & Powered Relay (WiSPR Sensor) is a wireless hub that is used exclusively
to relay sensor data from internal, connected and WiSH sensors back to the Room Alert 32W and 26W
IT environment monitoring hardware . The WiSPR Sensor communicates ONLY with Room Alert
WiSH Sensors, the Room Alert 32W and the Room Alert 26W via a secure, private protocol on a ZigBee
based 2.4 Ghz wireless connection. Data sent and retrieved is encrypted and will not interfere with other
wireless devices in the environment.
The WiSPR Sensor is a small surface mountable device that
includes mounting screws. It consists of one (1) built-in Digital
Temperature Sensor, two (2) External Environment Sensor Channels
(i.e. digital sensor ports) for connecting AVTECH digital sensors
and one (1) Switch Sensor Contact Set for connecting
non-voltage switch sensors. The WiSPR Sensor is plugged directly
into a power source via AVTECH’s 5V power adapter.
Additional environment sensors can be connected to the WiSPR using the two (2) digital sensor ports
and set of switch sensor contacts on the unit. The digital sensor ports can accommodate an AVTECH
Software Digital Temperature, Digital Temperature/Humidity, Digital Fluid or Digital Outdoor
Temperature Sensors. The set of switch sensor contacts can be used to monitor any connected non-
voltage switch sensor or dry contact device. See the respective sensor application note for more
information. The WiSPR Sensor also acts as a relay and repeats information from configured WiSH
sensors to the Room Alert 32W and/or 26W unit so that users can extend the length between WiSH
sensors and the monitorting unit.
Initial configuration of the WiSPR Sensor is performed after the initial setup of the Room Alert 32W
and/or 26W unit (as with the WiSH Sensor) and as directed in the appropriate User’s Guide & Reference
Manual. Once this is completed, activate the WiSPR Sensor by depressing the red button on the left side
of the WiSPR Sensor until it clicks and locks. If the red button is recessed, the WiSPR Sensor is ‘On’. If
the red button is flush with the WiSPR Sensor casing, the WiSPR Sensor is ‘Off’.
If multiple WiSPR Sensors are being configured during setup, it is recommended that you do so one
at a time. This will allow you to record the serial number (internal chip serial number) of each WiSPR
Sensor to the label on the back of each WiSPR Sensor. These internal serial numbers are displayed in the
Room Alert 32W and/or 26W ‘Status’ screens as each WiSPR Sensor device is discovered. After recording
the serial number on to the WiSPR Sensor label, the WiSPR Sensor can be moved to the desired location at
a distance of up to approximately 250’ away from the Room Alert 32W and/or 26W unit. If the monitoring
unit stops receiving updates from the WiSPR Sensor, move the WiSPR Sensor closer to the Room Alert
32W and/or 26W or away from any device or structure that may be impeding signal transmission.
