Q1: Where can I go to get a basic understanding of UL 325 and its history?
Q2: How is UL 325 7th Edition different from UL 325 6th Edition?
Q3: What is the minimum number of external entrapment protection sensors (combination of photo eyes and edge sensors) required in a typical automated gate installation?
Q4: Explain what monitoring is
Q5: How does an operator monitor an external sensor?
Q6: How many monitored external sensors can I connect to a Nice or HySecurity operator?
Q7: Since an edge sensor is a normally open (NO) contact, how is it possible to monitor this?
Q8: Why does HySecurity recommend hard wiring an edge sensor and avoiding use of a wireless edge transmitter?
Q9: I normally install 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 Nice or HySecurity gate operator?
Q11: What devices have been tested for use with Nice or HySecurity gate operators?
Q12: Can any UL Recognized or ETL Listed sensor be installed with any UL or ETL Listed gate operator?
Q13: Does Nice/HySecurity recommend a specific brand of edge sensor?
Q14: Does HySecurity recommend a specific type of edge sensor on a swing gate?
Q15: What other key changes were made to the 7th Edition UL 325, effective 8/1/2018?
Q16: If an older HySecurity Smart Touch or Smart DC board requires replacement, do I need to change the installation to comply with the UL 325 - 2018 standard? If an older Nice 936 or 1050 Controller requires replacement, do I need to change the installation to comply with the UL 325-2018 standard?
Q17: Do gate operators manufactured prior to August 1st, 2018 require Monitored Entrapment Protection Sensors?
Q18: Can I update an older Nice or HySecurity operator to meet the new 2018 UL 325 standard?
Q19: What UL 325 inspired changes may impact my external sensor choices?
Q20: What I can do to assure more reliable photo eye performance and less false tripping?
Q21: If I add monitored entrapment protection sensors and download a software update from HySecurity into an older HySecurity gate operator, won’t that force me to update to comply with UL 325 – 2018?
Q22: Can I use a new Edge sensor (with a resistor) on an older gate operator without a monitoring circuit?
