What is an intruder alarm system and why must it be inspected
Electronic security system (ESS), in older terminology referred to as PZTS, i.e. Alarm and emergency protection system, is a technical device designed to detect unauthorised entry, burglary or assault. It consists of motion sensors, magnetic contacts on doors and windows, sirens, control panels and a communication module that sends alarms to a central monitoring station (PCO) or directly to a mobile phone.
Like any technical equipment, an alarm system wears out over time. Batteries in sensors and the backup power supply discharge, contacts corrode, and communication modules may lose connection. A system that has not been inspected may fail at a critical moment, and the owner will be unaware of this.
That is precisely why we exist. inspection of intrusion alarm systemsregular expert inspection to verify that the system is operational and complies with current technical standards.
Legislative and regulatory framework
In the Czech Republic, inspections of alarm and security systems are governed primarily by the following standards:
ČSN EN 50131
Standard for alarm security and emergency systems. Specifies technical requirements for the design, installation, operation and maintenance of EZS. Divides systems into categories 1 to 4 according to the level of protection, higher categories correspond to higher security requirements and stricter rules for inspections.
ČSN EN 62676
Standard for CCTV systems connected to the building's security system. If the camera system is part of the alarm system, it is also subject to inspections.
Insurance policy terms of insurance companies
Most commercial insurance companies require a valid inspection report as a condition for claim settlement in the event of a burglary. Without a current inspection, the insurance company may refuse or reduce the payout.
Initial vs. Periodic inspection
Initial inspection
The initial inspection is carried out when the system is first put into operation. That is, after completion of a new installation or following a major renovation. It verifies that the system was installed in accordance with the project documentation and complies with standards.
The output is an initial inspection report, which is essential for:
- Termination or reinstatement of an insurance policy covering an intruder alarm system (EZS)
- Commencement of contract with PCO
- Handover of the system to the building manager in case of property rental or sale
Periodic inspection
Periodic inspection is a regular check of the operational functionality of the system. Unlike the initial inspection, it is not carried out only once but repeats at regular intervals.
| Kategorie | Typical use | Recommended interval |
|---|---|---|
| Kategorie 1 | Apartment building, flat | once a year |
| Kategorie 2 | Detached house, small office | once a year |
| Kategorie 3 | Shop, warehouse, larger office | 1-2 times a year |
| Kategorie 4 | High-risk workplaces | Twice a year or as per project |
Always verify the specific requirements in your insurance policy. It may stipulate a shorter interval.
What is checked during an inspection
Standard periodic inspection includes:
- Detectors and sensors - PIR sensors, magnetic contacts, vibration sensors, mechanical mounting
- Sirens and alarm indicators - internal and external sirens, flashing beacons, housings
- Backup power supply - battery capacity, runtime during a 230V outage, batteries in sensors
- Communication module - GSM/IP transmission, test alarm to PCO, backup communication
- Keyboards and controllers - functionality, range, correct settings
- Cable distribution systems - visual inspection, tamper loops, mechanical resistance
- Incident Log - records of alarms and service interventions since the previous inspection
How inspections are carried out in practice

Frequently Asked Questions
Am I legally required to have my alarm inspected?
There is no direct legal obligation for private properties to undergo alarm system inspections. However, this requirement is typically imposed by insurance terms and contracts with the central monitoring station.
What happens if I do not carry out the inspection?
The insurance company may refuse or reduce the payout on the grounds that the system was not in operational condition. In practice, this can result in a loss of hundreds of thousands to millions of Kč.
How long is an inspection report valid?
The inspection report has no fixed validity period. It remains valid until the next inspection is carried out. Insurance companies typically accept a report not older than 12 months (for annual periodicity).
Can I have inspections and servicing carried out by different companies?
Yes, it is not a requirement that the inspection be carried out by the same company that installed the system.
Conclusion
Inspection of an alarm system is a relatively inexpensive and quick matter that can save you significant money in the event of an insurance claim. Do not unnecessarily postpone it: a system that worked last year may not function today.
