following:
1. Click S1 on the PU one time.
2. Click S2 on the PU one time Only the green LED on the right should be illuminated.
3. Click S1 the number of times that you want to set the sensitivity threshold to be set. One click is
most sensitive (lowest threshold), with more clicks making it increasingly less sensitive.
4. Click S2 to save the new sensitivity threshold.
Install power supply and wiring (non-battery operated systems)
The TMD network can be powered by any DC power supply of 312 volts capable of providing 50mA of
current to each node. It is recommended to use a battery backup system on the power supply to account
for outages. For demonstration or portable deployments, batteries can be directly wired to the nodes and
PU. The devices can be wired in parallel with the power supply, as shown in the illustration below.
Install grommet and thread power wires to each node
For each node location, choose a punchout hole (bottom or back) on the plastic enclosure and punch it
out using a screwdriver or other pointed tool. The bottom punchout hole is convenient for wires that run
along the inside wall, and the back side punchout is useful when the wire comes straight out of the wall.
