Important UL 325 – 2016 Software Update. HySecurity Operators – Simplified.

by HySecurity Marketing
All HySecurity operators will now function with a minimum of ONE external entrapment protection sensor connected -- either a photo eye or edge sensor (wired or wireless).

All HySecurity slide gate operators manufactured on or after Monday, October 3, 2016 will function like the current HySecurity swing gate operators: Only one external entrapment protection sensor* (edge sensors or photo eyes) needs to be installed to enable fully automatic operator functionality. HySecurity has changed its software to conform to the industry accepted interpretation of UL 325 6th Edition, the currently effective standard for gate operators.
*Except UL Class IV operators, which do not require any external entrapment protection sensor

Software updates are now available for download at www.hysecurity.com.
h4.56 for Smart Touch Controllers (STC)
h5.57 for Smart DC Controllers (SDC)
NOTE: HySecurity S.T.A.R.T. software version 3.02 may still be used to upload this software update into operators, however S.T.A.R.T. software, version 3.03 will be required to permit programming operator menu settings. S.T.A.R.T. software, version 3.03, will be available from the HySecurity website by May 1, 2018. Until then, program operators using the operator keypad.

This software update ALSO includes:
  • Support for HydraWedge SM50 (OT 10)
  • Improved dual gate functionality
  • Reduces instances of false error codes;
    • Error 4 (primary/secondary RS-485 communication failure)
    • Fault 2 (monitored photo eye fault)
Distributors and installers with post January 12th, 2016 HySecurity operator inventory should install this software upgrade to take advantage of the new updates. Log in to your HySecurity Distributor or Installer portal at www.hysecurity.com to download the updated operator software.

Wireless edge sensor for sliding gates? Think again. HySecurity recommends . . .
What’s the most important area to protect against entrapment? Choose one.
  1. Draw in zones at fixed posts?
  2. The leading end of the gate?
  3. The trailing end of the gate?
If you chose #1, you’re right. See below:

 Slide Gate Entrapment  Protection

It’s been standard installer practice to install the first edge sensor on the leading end of a slide gate. That calls for a wireless edge sensor. It seems intuitive because most installers believe the leading end is the obvious slide gate entrapment zone. However, history shows that the most frequent and worst accidents have occurred when a person is drawn into the space between a gate and a fixed object, when gate is moving in the open direction of travel. That’s the most important slide gate entrapment zone to protect against, whether on the public or private side. The best protection for the draw-in zone of a sliding gate are edge sensors.

HySecurity recommends installing WIRED EDGE SENSOR(S) to protect against draw-in entrapment.

Five additional advantages of wired edge sensors:
  1. Wireless edge transmitters result in service calls when their batteries fail.
  2. Our tech support calls clearly indicate that the new monitored wireless edge receivers experience an unacceptably high fault indication rate. This seems to be primarily due to a high sensitivity to RF interference and the new requirement for continuous monitoring.
  3. Hard-wired edge sensor(s) work more reliably in the field – see # 1 and 2.
  4. Edge sensor(s) work faster, and perform better, when they are hard-wired.
  5. The expensive monitored transmitter/receivers are not needed if the gate closing travel is protected with a photo eye.  
The UL 325 Standard of Safety will constantly evolve to improve safety
UL 325 6th Edition hasn’t changed yet, but is being rewritten. The next revision will clarify the MINIMUM number of sensors required to meet the standard for each operator type (slide, swing, etc.) The standard hasn’t changed yet, but because everyone, including the testing labs, have been interpreting the current standard differently, it will be reworded and improved.

The final judge
UL 325 Standard of Safety provides the MINIMUM safety standards. Site, gate hardware usage, and other conditions may dictate the use of additional safety designs/components. It is up to the gate system designer and installer to assess appropriate safety design and install the components required to protect all entrapment zones. Always check your local area codes and comply with all standards and regulations.
Expect more . . . stay tuned
Industry standards will continue to evolve and HySecurity constantly reevaluates methods to improve safety. Stay tuned for future announcements.
