    Backup Power Supplies for Facility Lights

    Backup Power Supplies
    Image of Product. Back orientation. Backup Power Supplies. Backup Power Supplies for Facility Lights, Backup Power Supplies.
    Turn your facility lights into emergency lights—no need for generators or separate backup lights. Also known as battery inverters, these power supplies detect outages and shift your lights to battery power. To comply with UL 924 and help you meet NFPA standards, they activate your lights at full brightness for at least 90 minutes, even if they’re off or dimmed. A low-voltage disconnect extends the life of the battery by switching it off before it’s fully drained.
    An LED indicator tells you whether your lights are using primary or backup power. The indicator also tells you when these power supplies require maintenance. They have a manual test switch, so you can test them without disrupting the power.
    If you have more than one circuit, you’ll need to add a relay to bypass dimmers and on/off controls across circuits. You can also wire these relays to your fire alarm. Pull the alarm to activate lights to full brightness during emergencies, even without an outage. Also known as automatic load control relays.
    Maximum Recommended Power—Maximum recommended power is the total wattage of connected devices that these power supplies can support.
    Cannot Be Sold To—Power supplies that cannot be sold to the listed areas are restricted due to local energy efficiency requirements.

    Relays have an LED indicator that tells you if your lights are using primary or backup power and when these relays require maintenance. They also have a test switch to make sure the system is working.
    Unthreaded Through-Hole Mount—Relays that mount into an unthreaded through hole install into knockouts in junction boxes and light fixtures.
    Fastener Mount—Fastener-mount relays are ideal when space is tight or you want to hide your relay. They fit inside a ballast channel to keep everything contained within your fixture housing.
