UL 325 FAQ

UL 325-2016 Standard for Safety
Frequently Asked Questions regarding UL 325-2016 changes and the monitored entrapment protection sensors requirement:
Q1: What UL 325 changes become mandatory on January 12, 2016?
Q2: How many external entrapment protection sensors (as a combination of photo eyes and edge sensors) are required in a typical automated gate installation?
Q3: What choices did manufacturers have in order to comply with the UL 325 mandate for Monitored Sensors? Did it require significant changes to their operators and if so, what does that mean to me?
Q4: How many monitored external sensors can I connect to a HySecurity gate operator?
Q5: Since an edge sensor is a normally open (NO) contact, how is it possible to monitor this?
Q6: Can the warn-before-operate audio alert be used as one of the UL 325 Entrapment Protection devices?
Q7: Can the vehicle loop be used as one of the UL 325 Entrapment Protection devices?
Q8: Can I use the new blue-taped Miller edges with a 10k Ohm resistor on 2015 and older gate operators without a monitoring circuit?
Q9: I normally installed edges sensors on the leading and trailing end of a sliding gate. Isn’t that the best way to protect against entrapment?
Q10: What happens if one of the external Entrapment Protection sensors becomes disconnected or fails in a HySecurity Gate Operator?
Q11: Does HySecurity recommend any specific type of edge sensors in certain applications?
Q12: What photo eyes and edge sensors have been tested for use with HySecurity gate operators?
Q13: Can any UL Recognized or ETL Listed entrapment sensor be installed with any UL or ETL Listed gate operator?
Q14: If a 2015 or older HySecurity Smart Touch or Smart DC board requires replacement, do I need to change the installation to comply with the new UL 325 2016 standard?
Q15: Do gate operators manufactured prior to January 12, 2016 require Monitored Entrapment Protection Sensors?
Q16: Will I have to update previous installs or gate operators manufactured prior to 2016 to meet the requirements for Monitored Entrapment Protection Sensors?
Q17: Can I update an older HySecurity operator to meet the new 2016 UL 325 standard?
Q18: What UL 325 inspired changes may impact my external sensor choices?
Q19: In the past, I’ve had issues with photo eyes, especially reflective photo eyes that have falsely held a gate open. Is there something that I can do to assure of reliable photo eye performance?
Q20: If I download a software update from HySecurity into a pre-2016 gate operator, won’t that force me to update to comply with UL 325 – 2016 and add monitored entrapment protection sensors?
Q21: Why did HySecurity choose the Normally Closed (NC) method to monitor external entrapment protection sensors?
