Alarm and communication must work when power fails
We check the entire chain: power supply point, UPS/DC, batteries, overvoltage and lightning protection, generator circuits, autonomy time and restoration procedure.
We only publish a general scope on this page — we do not publicly disclose the locations, power, routes, or autonomy times of specific systems.
Scope
Systems whose power supply is covered by a common scenario.
- Sirens and local warning systems
- Radio stations and communication points
- Crisis management centres
- Network devices, servers, and operator workstations
- Base stations or retransmission points within the client's scope
- Monitoring, access control, and security systems
- Charging of portable devices
What we check
Eight items — from required operating time to recovery test.
- Requirementsrequired operating time and system priority
- Loadactual consumption and battery status
- Redundancypower supplies and routes
- Protectionsurge, lightning, earthing
- SwitchingUPS behaviour when switching to generator
- Monitoringpower and battery failures
- Procedureoperator instructions and escalation path
- Testautonomy and recovery
Result
Matrix of system — required autonomy — test result, list of single points of failure, battery replacement and modernisation plan, test protocol, procedure for power outages, and acceptance criteria for new or modernised systems.
Information security
We do not publicly disclose the locations, power, routes, configurations, or autonomy times of specific systems. Details are provided to persons designated by the client.
Basis
The OLiOC Act and Programme cover threat detection, alarming, notification, communication, and continuity of energy supply systems.
Questions and Answers
Does the test require switching off the alarm system?
The test scenario is agreed in advance: scope, time window, function safeguarding, and consent of responsible persons. The autonomy test itself cannot trigger the event the system protects against.
Do you publish the autonomy times of our systems?
No. The public page contains only a general scope of service. Results, configurations, and autonomy times are only provided to persons designated by the client.
Batteries have been replaced — why an audit?
Battery replacement does not confirm the autonomy of the entire chain: power supplies, routes, surge protection, generator switching, and monitoring also determine whether the system will function. The audit concludes with a test, not an invoice for batteries.
Unit registration form
Ref.: OL/2026/ALARM · response: office hoursOne submission is enough — the coordinator will come back with technical questions or a proposal for scope and deadline.
Information security: do not send classified information, facility diagrams, evacuation routes, or security details via the public form. We exchange OPZ documentation through an agreed, secure channel after contact is established.
