Security from both inside and outside! 【Keylex Double-Sided Button Series】

Ideal for places where you want to restrict not only external intrusions but also internal exits! You can set separate passcodes for inside and outside!

The "Keylex Double-Sided Button Series" features button locks (Keylex) on both the inside and outside of the door, allowing for access control using a passcode whether entering from indoors or exiting outdoors. You can set different passcodes for the inside Keylex and the outside Keylex, enabling you to have two separate passcodes: one for entry and one for exit. (Of course, you can also use the same code for both sides.) Each Keylex comes with a double-sided button option, allowing you to use it according to your needs. For example... - I want an auto-lock feature or one with a key (*1)! - I want to change the passcode without removing it from the door! - I prefer a compact type! - I want to use it on sliding doors! We have a wide variety of options to meet various requests. *For more details, please refer to the PDF document or feel free to contact us. (*1) Keyed: This type has a cylinder built into the Keylex body, allowing it to be unlocked not only by the button but also with a key.

HK-2

Recommended for earthquake measures for automatic doors and equipment! Seismic device HK-2.

  • NEW
  • PRODUCT

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.

When the sensor detects a car, it notifies pedestrians of the car's departure with the light of a rotating beacon!

Perfect for entrances and exits of parking lots and stores! Notify pedestrians of vehicle departures with the light from the rotating lamp! Here is a proposal for a departure warning sensor!

  • NEW
  • CATALOG

[To the owners of parking lots and parking lot construction companies] "I am worried about the possibility of colliding with pedestrians when exiting the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, those particularly facing sidewalks or roadways are expected to pose risks of dangerous incidents such as pedestrian collisions and vehicle-to-vehicle accidents. To alleviate such concerns, Hotron proposes a [Vehicle Exit Warning Sensor] that detects vehicle departures at various sites and alerts the surrounding area with LED lights and buzzers. The system consists of a simple configuration of "Sensor" + "Controller" + "Switching Power Supply (24V)" + "LED Rotating Light." *When using the exit warning system, we kindly ask that you arrange for the switching power supply (24V), LED rotating light, control panel, circuit breaker, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. [Contents Included] ○ Exit Warning System Configuration ○ Comparison Table of Exit Warning Sensors ○ Four Modes ○ Wide Range of Applications ○ Customer Feedback ○ Appearance Diagram / Specifications ◎ For more details, please contact us or download the catalog.
