The HSA is an electrically controlled closer/holder designed to provide easy passage for groups of pedestrians through high traffic doors.
- In 2006, we changed the Scanner in all HSA units to a smaller design. If the customer has an old unit prior to 2006, they can replace the old scanner with the new (current) scanner but they would need to take the plastic window cover out of the metal cover for the unit to function. The only downfall is that this will leave an open cutout in the cover.
- 11/15/2009, The HSA series was discontinued, and could be replaced by the 4314ME/4414ME series closers with the optional "B80" cylinder. Then use an additional sensor like a "Scan II" in conjunction with the "ME" closer. The Scan II will control the hold open feature when the door has power applied to it. See Point to Point wiring diagram here.
- 3/18/2013, The 4310HSA/4410HSA Series was re-introduced back to the product line, eliminating the need to replace the older version with an "ME" closer.
