CLEARcommand Voice Alarm Lockdown System

One system. Clear instructions. For every emergency.

Introduction

Whether the situation calls for a security lockdown, an invacuation, a chemical hazard warning, a perimeter alert, or a general safety announcement, CLEARcommand ensures that the right message reaches the right people at the right moment.

Where a conventional sounder can only signal that an incident has occurred, CLEARcommand tells people exactly what to do — reducing confusion, accelerating response, and improving outcomes across every type of emergency a building may face.

The Case for Voice Alerting

Modern buildings face a diverse range of emergency scenarios, and each one demands a different response. Telling occupants to evacuate when they should be sheltering in place — or vice versa — can turn a manageable situation into a dangerous one. Pre-recorded voice messages remove that ambiguity entirely, delivering clear, authoritative instructions the moment an incident is triggered.

CLEARcommand gives organisations the capability to communicate with precision for every scenario they plan for — from everyday safety announcements to the most serious critical incidents.

Benefits

Unambiguous Communication

Spoken voice messages eliminate the uncertainty of tone-only alerts, ensuring occupants know immediately what action to take — whatever the nature of the emergency.

Multi-Scenario Ready

A single CLEARcommand system supports multiple pre-configured voice messages, covering different incident types from a unified platform. One investment protects against every eventuality.

Simple to Activate

Distinctive blue call points with protective covers allow fast, single-action triggering of the correct message — making the right response instinctive even under pressure.

Instant Remote Notification

The GSM mobile communicator delivers real-time alerts to key personnel wherever they are, ensuring a coordinated response begins from the very first moment of an incident.

Scalable Coverage

The sounder splitter module converts a single sounder circuit into four, enabling efficient, cost-effective coverage across buildings of any size and layout.

Supported Scenarios

     Security Lockdown and Invacuation

When a threat is identified inside or near a building, the speed and clarity of your response can determine the outcome. CLEARcommand delivers an immediate, pre-recorded voice message instructing occupants to move away from windows and doors, remain in place, and await further instruction — removing the guesswork from a situation where guesswork costs lives. Unlike a tone-only alarm, there is no ambiguity about what occupants should do or why.

Invacuation — bringing people inside a building quickly and safely — demands a different message to evacuation, and CLEARcommand is designed to deliver exactly that distinction. With scenario-specific call points and protective covers ensuring the right message is triggered every time, staff can initiate a full building invacuation with a single, confident action. The system's GSM communicator simultaneously alerts key personnel off-site, enabling a coordinated response from the very first moment.

     Perimeter and Security Breach

A perimeter or security breach requires immediate, controlled communication to prevent panic and direct occupants away from the affected area. CLEARcommand broadcasts a clear spoken alert that identifies the nature of the threat and instructs people to move to designated safe areas — ensuring an orderly, directed response rather than uncoordinated movement that could inadvertently place people in harm's way.

Effective perimeter management depends on everyone receiving the same instruction at the same time. CLEARcommand's scalable sounder network ensures consistent voice coverage across every zone of a building, from open-plan offices and corridors to stairwells and external areas. Security teams and building managers receive simultaneous notification via GSM, allowing them to act on verified information while the system handles building-wide communication automatically.

     Chemical or Hazardous Material Incident

In the event of a chemical spill, gas leak, or hazardous material release, the instinct to evacuate is not always the right one. CLEARcommand can be configured to deliver shelter-in-place instructions — directing occupants to close windows and doors, turn off ventilation, and remain inside until the area is declared safe. Delivering this message clearly and immediately, rather than relying on staff to communicate verbally in a chaotic environment, can significantly reduce exposure risk.

Where evacuation is the correct response to a hazardous material incident, CLEARcommand ensures occupants are directed away from the affected zone via pre-planned safe routes. Pre-recorded messages can specify which exits to use and which areas to avoid, providing the kind of actionable guidance that a standard sounder simply cannot convey. Multilingual message capability further ensures that instructions reach every occupant, regardless of language.

      Smoke Curtain Activation

Smoke curtains are a critical element of a building's passive fire protection strategy — but their effectiveness depends entirely on occupants responding correctly when they deploy. CLEARcommand can be integrated to deliver a simultaneous voice message at the point of smoke curtain activation, instructing people to stay clear of descending curtains and move calmly to the nearest safe exit. This removes the risk of occupants being startled or obstructed by a curtain they were not expecting.

Coordinating smoke curtain activation with a spoken voice alert also supports the work of fire marshals and first responders, who can focus on managing evacuation rather than manually directing people away from active curtain zones. With CLEARcommand, the system communicates for them — delivering consistent, authoritative instructions at exactly the right moment across every affected area of the building.

     General Building Safety and Information Announcements

CLEARcommand's capability extends beyond emergency scenarios. The same infrastructure that handles critical incident response can be used for day-to-day safety communications — from fire drill notifications and lone worker check-ins to routine building announcements and visitor guidance. This dual-purpose functionality maximises the return on investment while keeping occupants familiar with the system's voice, so they respond confidently when it matters most.

Building managers can use CLEARcommand to broadcast scheduled or ad hoc announcements across all zones or targeted areas, maintaining clear lines of communication without requiring additional infrastructure. Whether informing staff of a planned maintenance shutdown, reminding occupants of assembly point locations, or conducting a routine drill, CLEARcommand ensures every message is heard clearly, consistently, and without confusion.
