Smoke Systems by Locked and Secure
Deter intruders instantly with our advanced Smoke Systems. When triggered, these systems release a thick white fog that blocks visibility within seconds, stopping criminals in their tracks and protecting your property, staff, and assets.

MASKING THE ROOM
What are smoke systems?
Smoke systems create an immediate visual barrier inside your premises when an intrusion is detected. Once triggered by your alarm, the unit releases a dense white smoke that fills the protected area within seconds, cutting visibility to almost zero. With no clear line of sight, intruders cannot find valuables or navigate the space, forcing them to abandon the attempt quickly.
The smoke is safe for occupants and stock, designed for internal use, and ideal for shops, warehouses, offices, server rooms, and homes. The system can work as a standalone deterrent or integrate with your intruder alarm and monitored CCTV, providing rapid protection while police or keyholders attend.
By removing visibility and slowing movement, smoke systems significantly reduce loss, limit damage, and protect staff and customers during an incident.
What else you should know about smoke systems
- The smoke is harmless, specially formulated for security use, and disperses naturally with normal ventilation.
- Visibility drops within seconds, preventing intruders from moving around or identifying targets.
- The smoke leaves no abrasive residue, making it safe around electronics, stock, and furnishings when used correctly.
- Units can protect individual rooms or large open spaces, and multiple generators can be linked for wider coverage.
- Systems integrate seamlessly with existing intruder alarms, keypads, and monitoring setups, activating automatically when a confirmed alarm is triggered.
- Running costs are low, with only fluid refills and periodic checks required.
- Regular testing and servicing ensure consistent performance, while warning stickers act as a visible deterrent before any intrusion occurs.
- Perfect for retail counters, storerooms, cash offices, warehouses, showrooms, and high-value residential areas.
