APPENDIX A: Checking Your Skymetry WTU-14
for Proper Operation
We recommend that you test your Skymetry WTU-14 weekly to be
sure it is functioning properly. This will ensure that when a problem
arises the Skymetry WTU-14 will be ready to alert the appropriate
personnel. A blank Test Log is included at the back of this manual.
There are several tests to be performed:
1. Request a Status Report from the unit by sending it an e-mail
message and verifying the reply. This will test the unit’s ability to
receive and send a message. It will also verify that all of the inputs
are reading properly, the alarm conditions are OK, the electricity is
on, and the battery is OK.
2. Create an alarm on each input by tripping all connected sensors.
This will verify that each input is being recognized by the unit and
that it is programmed properly.
Temperature sensors: Heat or cool the sensor.
Motion sensors: Have someone walk in front of the sensor.
Door and window sensors: Open the door or window.
Water sensors: Apply a small amount of water beneath the sensor
or use a wet towel and touch it to the sensor probes.
Humidity sensors: Raise the humidity around the sensor by hold-
ing a cup of very hot water beneath it.
4–20mA Transducers: Verify that the WTU-14 is reading the prop-
er level by measuring the monitored quantity using alternative
methods.
Allow the unit to send its alarm message to all programmed con-
tacts. This will make sure that the WTU-14 is programmed properly.
It will also prepare personnel to respond appropriately when they
receive a call from the WTU-14.
