What is EN 50131 grading and which grade do I need for my property?

EN 50131 is the European standard for intruder alarm systems (accepted internationally). Grade 1: Low security — residential homes with general household theft risk. Grade 2: Medium-low security — commercial offices, shops, residential complexes — requires 24-hour battery backup and anti-masking PIRs. Grade 3: Medium-high security — banks, jewellery stores, cash handling, high-value goods storage — requires dual-path monitoring, 72-hour backup, and dual-technology detectors. Grade 4: High security — government, defence, critical infrastructure. For India: Grade 2 is minimum for any commercial property seeking insurance compliance; Grade 3 for banking and high-value applications.

What is the difference between PIR and dual-technology detectors?

PIR (Passive Infrared) detectors sense changes in infrared radiation caused by moving warm bodies. They have a false alarm rate of 1–2% in standard quality products due to temperature changes, warm air currents, and small animals. Dual-technology detectors combine PIR with microwave motion detection — both technologies must trigger simultaneously to create an alarm. This reduces false alarm rate to below 0.01% — essential for Grade 2 and Grade 3 commercial applications. Dual-tech detectors cost 2–3x more than standard PIRs but dramatically reduce false alarm call-outs and alarm fatigue.

Can a wireless burglar alarm be jammed and how do I prevent it?

Basic wireless burglar alarms operating on fixed RF frequency (433 MHz) can be jammed with inexpensive RF jammers available online. High-security wireless systems use FHSS (Frequency Hopping Spread Spectrum) — continuously changing frequency prevents jamming. Additionally, Grade 2+ systems use supervision signals: the panel expects regular 'heartbeat' signals from each wireless device — absence of heartbeat triggers a tamper/fault alert even if the device is jammed. Always specify FHSS and supervision heartbeat for any wireless commercial security system.

What is central station monitoring and why is it important?

Central station monitoring connects your burglar alarm system to a 24/7 staffed security monitoring centre via telephone, GSM, or internet. When an alarm activates, trained operators verify the alarm (via CCTV integration or voice contact) and dispatch appropriate response — police, armed response, or key holder. Unmonitored alarms (local siren only) receive police response in less than 10% of cases in Indian cities. Monitored alarms increase police response rate to 45–65%. For Grade 2 and Grade 3 systems: monitoring is mandatory. Cost: ₹1,500–₹4,500/month depending on response level.

What RBI guidelines apply to bank branch burglar alarm systems?

RBI Master Circular on security of bank premises requires: intrusion alarm system with motion detectors covering all areas; door sensors on all entry points; panic/duress alarm for staff; CCTV integration with minimum 30-day storage; 24/7 monitoring with maximum 20-minute response commitment; quarterly testing with test records maintained for audit. Grade 3 EN 50131 systems meet RBI requirements. ATMs require additional: ATM cabinet sensor, cash removal sensor, and satellite-linked central monitoring. Non-compliance found during RBI inspection results in corrective action notice.
