Manaras-Opera complies to the revised United States National Standard: ANSI/UL325
As of August 29th, 2010, the United States ANSI/UL325 requirements for Commercial Door Operators was revised. In short, CDO's will now have to monitor an external entrapment protection device (photo cells, sensing edge) or must function in constant-pressure-to-close, in order bear a NRTL mark (UL, CSA).
What are the facts?
- UL325 is a National United States of America standard (ANSI). Other countries will have different requirements.
UL325 compliancy is voluntary.
UL325 is a design/manufacturing standard.
UL325 is not a law.
CDO's must have a means to monitor external entrapment protection devices (photo cells/sensing edge/other) or must function in constant-pressure-to-close.
If the entrapment protection system is not functioning properly, the CDO will revert to constant-pressure-to-close.
Photo cells or sensing edge protection devices will be monitored by the operator at least once during close cycle.
The operator plus the monitored photo cells or sensing edge must be tested as a unit by a Nationally Recognized Testing Laboratory (NRTL) (ex: CSA, UL, etc).
As an installing dealer, what are my options?
- Electronic control operator with monitored external entrapment protection device; either photo cells/sensing edge (several models will be available).
- Operator with constant-pressure-to-close only (no field modifications allowed).
