Security Alarm Active Sign – Motion Detection & Intruder Warning | A5, A4, A3 | Easi-Signs

Maximize Your Site Protection with the Security Alarm Active Sign

The Security alarm active sign is a vital asset for any property manager looking to reinforce their perimeter defenses. Featuring the industry-standard yellow warning background and a black triangular pictogram, this sign visually communicates the presence of sophisticated detection technology. The graphic depicts an intruder being caught in a sensor’s field, serving as a universal PIR motion sensor sign that transcends language barriers. By clearly displaying “Security alarm active,” you provide a definitive warning that your premises are not an easy target.

At Easi-Signs, we manufacture our security range to be both highly visible and authoritative. This specific sign is designed to work in tandem with your physical security hardware, bridging the gap between your technology and the psychology of deterrence. Whether it is used for a commercial warehouse, a construction site, or a private office, the presence of professional anti-intruder security signage tells visitors and potential trespassers that the site is under constant surveillance and that any unauthorized entry will trigger an immediate response.

The Critical Importance of Alarm Notification

Why is it essential to install a Security alarm active sign? First and foremost, visibility is the most effective deterrent against opportunistic crime. Most intruders will bypass a property if they believe their presence will be instantly detected. By advertising your 24 hour alarm monitoring, you shift the risk-reward calculation for any would-be trespasser. This sign acts as a constant, non-fatiguing security guard that never takes a break, ensuring your security message is delivered around the clock.

Beyond deterrence, there are practical and legal benefits to using clear security signage. Notifying people that they are entering a monitored zone can reduce the frequency of accidental alarm activations by delivery drivers or maintenance staff. Furthermore, in the event of an incident, having high-quality anti-intruder security signage prominently displayed demonstrates your commitment to due diligence and site safety. It establishes a clear boundary and informs everyone on-site that their movements are subject to electronic verification.

Sizing Options and Durable Materials

Easi-Signs provides this Security alarm active sign in three standardized sizes and two high-performance materials to suit any installation requirement:

• A5 Size (148 x 210mm): Best for close-range identification. These are frequently used on individual office doors, small side-gates, or near alarm control panels.
• A4 Size (210 x 297mm): Our most popular choice for general wall mounting. The A4 PIR motion sensor sign provides a clear warning that is legible from a standard distance, making it perfect for most business exteriors.
• A3 Size (297 x 420mm): Recommended for large-scale industrial sites or perimeter fencing. The A3 format ensures that the message of 24 hour alarm monitoring is visible from a significant distance, even in poor lighting conditions.

We offer two material specifications tailored for longevity:

1. Self-Adhesive Vinyl: A high-tack, flexible material with a protective gloss finish. It is ideal for application onto smooth surfaces like glass windows, aluminum door frames, or plastic cladding. It is UV-resistant and built to handle the elements.
2. 3mm Rigid PVC Plastic: This is a robust, impact-resistant material designed for permanent outdoor installation. It can be easily fixed to brickwork, timber fences, or metal railings using screws, bolts, or heavy-duty adhesives. This material ensures your Security alarm active message remains professional and intact for years to come.

Strategic Placement for Optimal Visibility

For your anti-intruder security signage to be most effective, it must be placed where it cannot be ignored. We recommend mounting the Security alarm active sign at all primary entry points—this includes the main driveway, pedestrian gates, and all exterior doors. Positioning the sign at a height of 1.5m to 1.7m ensures it sits at average eye level, maximizing the “first-glance” impact.

If your property uses 24 hour alarm monitoring with motion sensors, placing a PIR motion sensor sign near the actual sensor units can further discourage intruders by highlighting the exact technology in use. For large perimeters, signs should be spaced every 10-15 meters to ensure there are no “blind spots” in your security messaging. Trust Easi-Signs to provide the high-quality, compliant signage you need to maintain a secure and professional environment.
