INSTALLATION NOTES
• It is not necessary to install an ENVIROMUX-ACVD-xxx to monitor the AC circuit which provides power to the ENVIROMUX-
SEMS-16. The ENVIROMUX-SEMS-16 has built-in power monitoring and battery backup and will send an alert in the event
of a power failure.
• In order for the ENVIROMUX-SEMS-16 to send an e-mail alert, the attached network components (routers, mail server, etc.)
must have power. If you are using the ENVIROMUX-SEMS-16 and ENVIROMUX-ACVD-xxx to monitor the AC circuit
providing power to any of these network components, be sure they will not lose power during a fault condition. (See image
below.)
•
If your network components will lose power during the AC fault condition, use an alternate means to send alerts such as a
GSM Modem (ENVIROMUX-GSM) or Auto Voice Dialer (ENVIROMUX-AVDS). The ENVIROMUX-GSM and ENVIROMUX-
AVDS are powered by the “Aux Pwr” port on the ENVIROMUX-SEMS-16. (See image below.)
•
If you are using the ENVIROMUX-ACVD-xxx to monitor the AC Circuit which provides power to the ENVIROMUX-MINI or any
of the necessary network equipment (router, mail server, etc.), be sure they will not lose power during the AC fault condition.
