Intruder Alarm Grade Systems
Intruder alarm systems are categorized into different grades based on their level of security and the complexity of the risks they are designed to protect against. Here’s a summary of each grade and their main differences:
Grade 1: Low Risk
Description: Basic level of protection suitable for areas with a low risk of intrusion. Typically an ‘off the shelf’ DIY product that can be installed with limited technical ability.
Typical Use: Residential properties or outbuildings in low-crime areas, small businesses with minimal valuable assets.
Features:
- Simple DIY alarm systems.
- Basic sensors (e.g., door/window contacts).
- Limited or no tamper protection.
- Cannot be used for police response.
Grade 2: Low to Medium Risk
Description: Common professional alarm system providing enhanced protection for areas with a low to medium risk of intrusion. Parts and equipment are generally not available to the public and require installation by a security professional.
Typical Use: Residential properties in higher crime areas, small to medium-sized businesses (e.g., retail units, small manufacturing warehouses).
Features:
- Advanced detectors (e.g., motion sensors, glass break detectors).
- Enhanced tamper protection.
- Basic control panel with limited event logging.
- Can be remotely monitored but not essential.
- Can be used for police response if installed and maintained by an approved security professional
Grade 3: Medium to High Risk
Description: Higher level of protection suitable for homes or businesses with a higher risk level or valuable assets. Parts and equipment are not available to the public and require professional installation.
Typical Use: High-value residential properties, larger businesses, commercial properties (e.g., car dealerships, jewellery stores, electronic distributors).
Features:
- Advanced detection devices (e.g., multiple motion sensors, vibration detectors).
- Comprehensive tamper protection including anti-masking technology.
- Sophisticated control panel with detailed event logging and remote access.
- Increased number of zones and higher system reliability.
- Highly recommended for remote monitoring.
- Can be used for police response if installed and maintained by an approved security professional
Grade 4: High Risk
Description: Maximum level of protection for areas with a high risk of intrusion and high-value assets. Requires installation by a high security specialist.
Typical Use: Banks, casinos, military sites, and other high-security environments.
Features:
- Highly advanced detection systems (e.g., thermal imaging, active infrared beams).
- Full tamper protection.
- Complex control panels with extensive event logging, remote monitoring, and control capabilities.
- Multiple communication paths for secure alarm signal transmission.
- Must be remotely monitored, installed, and maintained by a security professional with police response capability.
Main Alarm Differences:
1. Risk Level: Grades vary by the level of risk they mitigate.
2. Detection Devices: Higher grades use more advanced detection technologies.
3. Tamper Protection: Increases with grade, including anti-masking technology at higher levels.
4. Control Panels: Become more sophisticated with higher grades.
5. System Reliability and Communication: Enhanced to ensure secure communication and reliable operation.
