Versatility allows the XPBB release device to operate on 120VAC, 24VAC, or 24VDC power sources. 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 4 smoke detectors and 2 horn strobes mounted on either side of the door. Programmable delay settings, close door detection, diagnostic LEDs, localized testing and reset capabilities are all also standard. Features include: • UL864/ULC-S527/S533 Listed • Programmable DIP switch delay setting – either 10, 20, 30, 60 second delay of door release to permit passage clearance Plus: • On board diagnostic LEDs for easy trouble shooting • Inputs for normally open 2- or 4-wire detectors and 4-wire normally closed detectors • Trouble and alarm relays for communication with the fire alarm control panel, if required • Audible trouble sounder to indicate when the release device is not operational • Testing function allows routine fire door testing without requiring activation of the smoke detector
