Description

The professional Dahua electromagnetic strike is a key element of modern access control systems, intercom, and video intercom installations. The device has been designed with maximum reliability and versatility in mind, which allows for trouble-free installation in various types of doors and gates made of metal sections, wood, or modern synthetic materials (PVC, aluminum). A solid construction based on high-quality metal alloys guarantees exceptional resistance to mechanical damage and long-term, trouble-free operation even in conditions of intensive use in public buildings or office buildings.

Specification

An exceptional functionality of the ASF702 model is the built-in signal output of the NO/NC/COM type. It allows for precise monitoring of the bolt status (open/closed), which is necessary in advanced intruder alarm (SSWiN) and access control (KD) systems, enabling the administrator to view the status of the entrance in real time. The universal design makes the strike ideal for both left and right doors, which eliminates errors when choosing equipment at the installation planning stage. Compact dimensions allow for aesthetic installation inside the door frame, without violating the visual character of the door joinery. This solution is dedicated to professionals looking for a compromise between strength, functionality, and ease of installation.

One of the most important advantages of this model is its huge mechanical strength – the bolt withstands pressure and dynamic load acting on the door of up to 500 kg, which significantly increases the level of security of the protected property. The strike operates in the 12V DC standard, characterized by an optimal power consumption of 320 mA. Thanks to this, it is fully compatible with most switching and buffer power supplies used in security systems.

1. Electrical parameters and power supply

Rated voltage: 12 V DC (direct current). The device requires a stable power source with a current efficiency of at least 400mA to ensure the correct operation of the electromagnet coil.

2. Power consumption and efficiency

Nominal power consumption is 320 mA during operation. This value is optimized for cooperation with UPS emergency support systems and buffer power supplies.

3. Mechanical strength and load

The permissible door load acting directly on the strike is 500 kg (approx. 5000 N). This guarantees high resistance to forced entry attempts.

4. Application and door direction

Universal and symmetrical design. Possibility of installation in right-hand and left-hand doors without the need to modify the device.

5. Internal memory function

The model does not have a memory function (None). The strike is unlocked only when voltage is applied. After the electrical impulse ceases, the bolt immediately returns to the locked state.

6. Mechanical latch lock

No mechanical latch lock switch. The device is controlled exclusively by electrical means, which increases the level of control over access to the facility.

7. Bolt operation mode

Standard operation (non-reversible). In the event of a power failure, the strike remains locked (closed). Opening occurs under the influence of an electrical pulse.

8. Adjustment and clearance setting

The model does not have a latch clearance adjustment. Precise fitting with the main lock takes place at the stage of mechanical installation in the door frame.

9. Monitoring and status outputs

Integrated status sensor with full relay output: COM (Common - Orange), NC (Normally Closed - Blue), NO (Normally Open - Yellow). Allows integration with alarm control panels.

10. Wiring description

1) White: Power supply (+, -); 2) Blue: NC (Monitoring contact); 3) Orange: COM (Common contact); 4) Yellow: NO (Monitoring contact).

11. Material and housing

The strike is made of durable high-density metal alloys, ensuring resistance to deformation under the influence of temperature and pressure.

12. Environmental conditions and installation

The device is intended for indoor use or in places protected from direct weather conditions. Operating temperature is stable in a wide range.

13. Physical dimensions

Body dimensions: 124 mm (height) x 32 mm (width) x 35 mm (depth). Compact size facilitates milling in metal and wooden profiles.

14. Warranty and manufacturer

Manufacturer: DAHUA. Warranty period: 2 years (24 months). The product has CE certification confirming compliance with safety standards.
