New safety alarm for use in construction site safety equipment.

スペースワークス スペースワークス シーリングシステム
■Overview of the Safety Alarm Device 1. This is a fire alarm device with security features that connects a fire memory sensor (switching function) to a general security alarm circuit composed of an alarm device, a pin switch, and a battery (DC 4.5V). 2. The pin switch is equipped with a strap and serves as a test switch for the alarm device, as well as an emergency switch. 4. In construction sites, the safety alarm device should be carried around (such as in work clothes or work bags). (1) For example, in emergencies due to health issues like heatstroke, or accidents caused by misoperation or malfunction of construction machinery, the pin of the safety alarm device carried around can be pulled out to sound the electronic buzzer for emergency alert. (2) For example, if a fire occurs after work, the fire memory sensor of the safety alarm device installed at the work site will detect the fire and sound the electronic buzzer to alert about the fire. 5. The device should be installed in areas at construction sites where there is a risk of fire (such as break rooms, work areas, material storage areas, temporary offices, temporary warehouses, and waste disposal sites). [Reference 1]: In the event of a fire, even if the case material of the safety alarm device deforms (melts), it will emit an alarm sound for about one minute. Depending on the fire situation, it can typically emit an alarm sound for about 20 minutes from the onset of the fire.

Construction fire alarm system

Early detection of fires caused by the use of fire at construction sites / New product for construction fire alarms

■Features of Construction Fire Alarm System 1. This is a construction fire alarm system that combines fire detection wires and alarms. It is an eco-friendly product with zero standby power. 2. By simply extending and wiring the fire detection wires, a wide fire alert area can be established, completing the installation. 3. It can quickly detect fires caused by the use of flammable materials at construction sites. 4. It can be easily installed in areas where flammable materials are used at construction sites. Installation and relocation are simple. 5. When the surrounding temperature reaches the set temperature (80°C), the two wires short-circuit to detect temperature and send a signal. 6. It directly senses temperature and sends signals through physical operation without the need for power sources or measuring devices. 7. It can be wired similarly to electrical equipment wiring and can be used for both indoor and outdoor wiring. 8. The product integrates numerous shape memory alloys at equal intervals of 0.5m along the wire (set temperature 80°C). 9. It utilizes the softening of the wire and the recovery of the shape memory alloy to short-circuit the two wires, detect temperature, and send a signal. 10. The shape memory alloy has permanent memory, is rust-free, and can be used for many years once activated. 11. This product meets the performance standards of type 1 fixed temperature detectors (120 seconds) as specified by fire safety regulations. 12. It is a non-resettable type that allows for confirmation after activation (once activated, it cannot be reactivated; the activated location must be deleted and reconnected).

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.
