This Security Alarm Warning sign informs individuals that an alarm will activate upon opening the door. Ideal for placement in retail stores, warehouses, or any facility with security systems in place, it acts as a deterrent for unauthorized access and helps maintain security protocols. Furthermore, the sign’s bright yellow background with bold black text ensures high visibility and readability to catch attention quickly. Next Day Safety prints these signs to order, often on the same day, to meet the regulatory requirements in Australia for having clear and visible safety signs in workplaces.
