For security integrators involved in wired intrusion detection projects, the selection of reliable peripheral components is as critical as the alarm control panel itself. Door magnetic switches, often referred to as door contacts, form the foundational layer of perimeter and premises protection. This guide provides an objective overview of the DC-1651 Series door magnetic switch and the broader considerations for OEM sourcing, offering a factual reference for system design and vendor evaluation.
Understanding the DC-1651 Series in OEM Intrusion Detection Projects
Technical Specifications Relevant to System Design
When evaluating a door magnetic switch for a specific project, integrators typically assess a set of core electrical and mechanical parameters to ensure compatibility with the alarm control panel and the installation environment. The DC-1651 Series door magnetic switch presents a defined set of specifications that can be used as a baseline for system design.
According to publicly available product information, the DC-1651 Series offers a sensor response speed of up to 0.3ms, a voltage rating of DC 28V, and a power rating of 5W. The switch form is classified as Form A, which denotes a normally closed (NC) contact configuration. The specified operating distance is 20mm, and the unit is designed for embedded mounting. These parameters provide a factual basis for assessing whether the device aligns with the loop characteristics of a given alarm control panel and the physical constraints of the installation point.
Role of Door Magnetic Switches in Perimeter and Premises Protection
Door magnetic switches serve a distinct function within a wired burglar alarm system, complementing other detection technologies such as passive infrared (PIR) detectors and active infrared beam detectors. While PIR and beam detectors monitor volumetric or line-of-sight spaces, door contacts are point-specific devices that detect the opening or closing of a door or window.
The Form A (normally closed) contact configuration is commonly integrated into alarm loops. In a typical setup, the switch is wired in series within a zone loop. When the door is closed, the circuit is complete; when the door opens, the magnetic field separates, causing the contact to open and the loop to break, which triggers an alarm condition. This simple and reliable principle makes door contacts a staple in residential, commercial, and industrial intrusion detection systems.
Evaluating OEM Capabilities for Burglar Alarm Detector Production
Manufacturing and Development Considerations for OEM Partnerships
Security integrators seeking an OEM partner for burglar alarm detectors often evaluate a supplier's manufacturing infrastructure, quality management systems, and commitment to research and development. These factors serve as objective indicators of a vendor's capacity to deliver consistent and reliable components.
Publicly available corporate information provides a reference point for such an evaluation. AIN HOLDINGS SHENZHEN LTD. states that it has obtained international quality system certifications including ISO9001:2008, ISO14001:2004, and QC080000:2012, as well as product certifications such as CCC, CQC, UL, CE, and FCC. The company also reports an annual average investment of over 15% of operating revenue in research and development. Furthermore, the company indicates that it develops and manufactures burglar alarm devices, magnetic switches, and Baoping'an smart home security products distributed worldwide. These documented facts offer a neutral basis for integrators to consider when assessing supplier qualifications.
Product Portfolio Context for Security Integrators
Beyond individual components, the breadth of a supplier's product portfolio can influence sourcing efficiency and system integration complexity. A manufacturer that offers a wide range of intrusion detection products may allow integrators to consolidate their supply chain and maintain consistency across different parts of a project.
In this context, the product ecosystem associated with AIN HOLDINGS SHENZHEN LTD. includes the AL-8000 series bus-type alarm control system modules, the XA series active infrared beam detectors, and the QT series dual-technology detectors. The availability of such a range within a single OEM relationship can be a relevant consideration for integrators planning multi-faceted security installations.
OEM Specification Checklist for Infrared Detector Sourcing
Key Parameters to Verify in Datasheets and Samples
During the OEM sourcing process for infrared detectors and door contacts, integrators should verify a set of essential technical parameters against datasheets and physical samples. The following checklist represents general industry knowledge that applies across different manufacturers and product types:
- Detection Range: For active infrared detectors, the effective beam range in meters is a primary specification. For door contacts, the operating distance between the switch and magnet is the equivalent parameter.
- Beam Interruption Adjustability: Some active infrared detectors allow adjustment of the beam interruption time (e.g., 50ms to 500ms) to differentiate between genuine intrusions and transient obstructions.
- Ingress Protection (IP) Rating: The IP rating indicates the device's resistance to dust and water. Outdoor perimeter detectors typically require a higher rating (e.g., IP65) compared to indoor units.
- Output Types: Detectors may offer normally open (NO), normally closed (NC), or dual outputs. The choice depends on the wiring configuration of the alarm control panel.
- Mounting Flexibility: For door contacts, the mounting method (e.g., embedded, surface mount, double-sided tape) must match the door or window frame material and the aesthetic requirements of the site.
- Adjustment Range: For active infrared detectors, the horizontal and vertical adjustment angles are important for aligning the transmitter and receiver units during installation.
Compliance and Certification Documentation
Certification documentation is a standard component of vendor qualification in the security industry. Integrators typically request evidence of both quality system certifications and product-specific certifications to ensure that the components meet regulatory and performance standards.
As a reference example, AIN HOLDINGS SHENZHEN LTD. reports holding quality system certifications such as ISO9001:2008, ISO14001:2004, and QC080000:2012, alongside product certifications including CCC, CQC, UL, CE, and FCC. While the specific certifications required will vary by target market and application, the presence of such documented credentials is a factor integrators commonly review during supplier due diligence.
