    Why Jewelry Stores in Spain Must Install Grade 3 Security Systems

    Grade 3 Security Systems for Jewelry Stores in Mallorca

    Running a jewelry business in Spain is not just about offering beautiful pieces to your clients. By law, jewelry stores are considered high-risk businesses, which means you are legally required to install a Grade 3 security system. This obligation is not optional. It is part of the Spanish Private Security regulations and is designed to protect both your store and your staff against theft or robbery.

    If you own or manage a jewelry store, it is essential to understand what “Grade 3” means and what type of protection you need to comply with the law.

    What is a Grade 3 security system?

    Security systems in Spain are classified by levels, called “grades”:

    • Grade 1 – very low risk, used for private homes without professional monitoring.

    • Grade 2 – medium risk, for houses or small shops.

    • Grade 3 – high risk, mandatory for jewelry stores, pharmacies, gas stations, and lottery offices.

    • Grade 4 – very high risk, for military sites or critical infrastructure.

    For jewelers, Grade 3 means installing professional equipment that has been officially certified. It also requires a direct connection to an authorized Alarm Receiving Center (ARC or CRA in Spanish), so that alarms are verified and the police can be notified immediately.

    Main components every jewelry store must have

    1. Intrusion alarm system

      • Motion detectors with anti-masking protection.

      • Magnetic contacts for doors, windows, and shop displays.

      • Seismic sensors for safes and strong rooms.

      • Indoor and outdoor sirens with tamper protection.

      • Devices that detect attempts to block or jam the system.

    2. Video surveillance

      • High-definition cameras covering all critical areas: entrance, counters, displays, and cash desk.

      • A Grade 3 certified recorder capable of storing video for a minimum of 30 days, as required by law.

      • Secure access control to recordings, so only authorized staff can review them.

      • Integration with the ARC, allowing operators to check images in real time to confirm if an alarm is real.

    3. Connection to the ARC (Alarm Receiving Center)

      • Mandatory 24/7 connection to a certified ARC.

      • Dual communication paths (internet and GSM/4G) to guarantee that the system never goes offline.

      • The ARC is responsible for verifying alarms and contacting the police instantly if needed.

    4. Physical barriers

      • Security doors certified at least Grade V according to European standards.

      • Motorized metal shutters for shop windows.

      • Laminated safety glass (P6B or higher) in showcases and windows.

      • Certified safes (Grade IV or higher) anchored to the floor or wall.

    Legal obligations you cannot ignore

    • The installation must be carried out by a licensed security company authorized by the Spanish Ministry of the Interior.

    • After the work is completed, you must receive an official installation certificate proving the system meets legal requirements.

    • You must sign and maintain a contract with an ARC at all times.

    • Regular inspections and maintenance are mandatory, and records must be kept.

    • The use of cameras must respect Spanish data protection laws (GDPR and LOPDGDD), including visible signs informing customers that the area is under surveillance.

    Why this matters for jewelers

    Failing to comply with Grade 3 security requirements can result in heavy fines and, even worse, leave your business unprotected in case of a break-in. A standard alarm or a basic camera system is not enough for jewelry stores. The law is very strict because of the high value of goods inside.

    By installing a proper Grade 3 system, you are not only following the law but also ensuring peace of mind for yourself, your employees, and your customers.

    Final thoughts

    Owning a jewelry store in Spain comes with clear legal duties in terms of security. Grade 3 systems are mandatory, and they combine professional alarm equipment, certified video recorders, constant monitoring by an ARC, and strong physical barriers like reinforced doors and safes.

    Choosing an approved installer is the only way to make sure your jewelry store passes inspections and stays fully protected. One of the best options in Mallorca is AlarmaBalear, a local company focused on grade 3 systems.
