Power supply connections
The LM100 gateway operates on 12 to 48 VDC. The power connection is made on removable
terminal block T6. In most cases, the luminaire AP’s power leads are also connected to T6.

Network power supply
When using a centrally located network power supply, ensure that the supply has sufficient
capacity if the gateway’s outputs will source power to auxiliary devices.
capacity if the gateway’s outputs will source power to auxiliary devices.
Local power supply
It is possible to use a local DC power supply when a source of AC power is readily available near
the gateway. The DC power supply must be installed in its own weatherproof enclosure. The local
supply can be mounted on the same post as the gateway to keep the wire runs to a minimum.

Power over Ethernet
For power over Ethernet, a class 3 PoE switch is required. In this configuration, minimum Category
5 cable must be used and the maximum distance between the gateway and the PoE switch is
100 m (328 ft.). Each gateway receiving PoE requires an earth ground connection. The PoE NIC
can also supply power for the luminaire AP.

Backup power
Senstar recommends that the Senstar LM100 system be powered from an uninterruptible power
supply (UPS). Connect AC mains to the UPS and the UPS to the DC power source. In this way, if
AC power is interrupted, the LM100 can operate on battery power while AC power is being
restored.

WARNING!
DO NOT bring AC mains power into the gateway enclosure. If a local
power supply is being used, it must be installed in its own weatherproof
enclosure. Consult the local electrical code for information about the
connection of AC mains to your power supply.
