Internal Battery Backup allows the release device to stand-alone from the fire alarm system and act independently in the event of a power outage. The system can provide 24VDC power for up to four smoke detectors and two horn/strobes, mounted on either side of the door. Programmable delay settings, closed-door detection, diagnostic LEDs, localized testing, and reset capabilities are also standard.
