6/18 – Alarm

Under the below circumstances, the Drop-arm Speed Gate System will automatically alarm and don’t open the door. Meantime, actively upload data to the monitoring system.


① Break into the gate

It refers to no legal signal being given, that is, an Unauthorized person entering. Or in the setting of no access mode, an Unauthorized person is forced to enter the gate. We can regard it as a break-in. The Turnstile Gate system will automatically alarm, and won’t open the door. Meantime, support uploads the signal to the monitoring system to capture.



② Collision

People force to push it when the door is locked, it will alarm. Anti-collision: KEEP KIND HEART adopts reliable electromagnetic clutch locking separation technology. When unauthorized people force to break in, first, the door will be opened at a little Angle (about 10°Angle) to prevent damage to the glass door & movement, then locked immediately. Next, automatically restore the original position and lock soon.



③ Tailgating

It means the person who follows closely behind doesn’t swipe the card. After the person in front passes, he takes the opportunity to enter asap. The access control system can detect pedestrian traffic conditions. When it detects the tailgating phenomenon, will alarm and close immediately before he enters.




④ Reverse intrusion

Its meaning is that pedestrians enter the passageway from the opposite direction before the finish of the passing process in one direction.


7/18 – Memorizing all passing requests

When more than two legitimate passing signals are given at the same time (including the same direction and reverse direction), the access control system will remember all passing requests and complete each passing action in turn. (Kindly note: Customers can set the number of memory and whether to choose memory function as requirements).

8/18 – Auto-lock

After the door is opened, if don’t pass within the set time, it will be automatically closed and locked.

9/18 – Attendance

16/18 – Supercapacitor Power Supply



KEEP KIND HEART selects the Supercapacitor as a standby power supply, which is used to withdraw the glass gate arm or drop the upper bar arm down for the tripod turnstile gate after a power failure so that the door is open under power off. It’s good for people’s evacuation.

Advantages of Supercapacitor Power Supply

(1) Shorter charging and discharging time: can quickly provide power support.

(It just takes 10 seconds to 10 minutes to reach 90% of the rated capacity. However, 30 minutes can only reach 75% for a lithium-ion battery.)

(2) Strong discharge capacity: higher energy conversion efficiency, smaller process loss.

(3) Longer cycle life: The repeated charging and discharging quantity of Supercapacitors can be up to hundreds of thousands of times. However, it can’t exceed 1000 times for the battery. It’s equivalent to a Li-Ion battery 500 times, and Ni-MH and Ni-Cd batteries 1000 times. Besides, the longer life helps save the time and trouble of often replacing the old battery with a shipping limit problem. (Kindly note: The low-configuration turnstile gates use batteries)

(4) Green environmental protection: The raw materials are non-toxic. At the same time, the production and use process haven’t pollution.

(5) Safe and maintenance-free: With a simple circuit, it no need for a charging circuit like a rechargeable battery. Besides, it has a higher safety factor, and is maintenance-free for long-term use;

(6) Higher Power Density: It equals 10 times more than lithium-ion batteries
