What is the mechanical power-off auto-open technology?

The mechanical power-off auto-open technology is an advanced technology developed by CMOLO in turnstile industry. By adopting the unique mechanism structure design, pedestrian turnstiles can automatically open without UPS power supply and with power failure, simply based on the pure mechanical structure.

In order to meet the fire safety requirements, the speed gate turnstile normally should open automatically in the event of power failure. It makes it easier to evacuate people in case of emergency.

Traditional Solution

The traditional solution is to install small backup UPS (uninterruptable power supply) inside the access control turnstile. When power failure, the UPS will supply electricity to the main control board and the relay will provide emergency opening signal to turnstile gate, so as to make the turnstile open automatically. The method is with simple mechanical structure, and easily to operate, so it is widely used in turnstile industry.

Shortcomings for traditional solution

This method's operation depends on the reliability of the relay, UPS, and the control circuits. Small backup UPS is usually made up by lead acid batteries and control circuit. Lead acid battery has a very short service life, and it has high risks of leakage and abnormalities of charging and discharging, and the control circuit of UPS power may be unnormal, which is unfavorable for environment protection. These shortcomings will affect the stability of the turnstile's auto-open function when power failure. If the turnstile's auto-open function is abnormal when power failure, it is likely to threaten the personal safety of users in the emergency.

How does CMOLO solve it?

CMOLO adopts pure mechanical structure, to achieve the auto-open function when power failure. The reliability of machinery is much higher than that of normal circuit and rechargeable batteries, greatly reducing the chances of putting people at risk. Besides, it also remove the risks from the failure of the relay, UPS & the control circuit. 

In this way, the mechanical structure is more complex and more difficult to design. Few companies can do it in the industry.

تم تطبيق تقنية الفتح التلقائي لإيقاف التشغيل الميكانيكي من CMOLO على البوابات الدوارة ذات البوابة السريعة والأبواب الدوارة ذات الحاجز الرفرف ، والتي تُستخدم بشكل شائع في مشاريع النقل بالسكك الحديدية. تجعل هذه التقنية حاجزًا للأبواب الدوارة دون الاعتماد على UPS بعد الآن ، وتضمن استقرار وظيفة الفتح التلقائي عند انقطاع التيار الكهربائي ، وتحسن مستوى بناء السلامة من الحرائق.
