Fire Sign: Fire Department Connection - 18" x 12" Aluminum

Fire Department Connection Sign — High-Visibility Reflective Aluminum for Code-Compliant FDC Identification

The Fire Department Connection sign (Part# LS-11555) is a professionally manufactured reflective aluminum safety sign designed to clearly identify fire department connection points on commercial and industrial structures. Built for contractors, fire protection installers, and facilities managers, this sign meets the demanding visibility requirements of active job sites and permanent installations alike. Available in three 3M reflective material grades, it delivers reliable performance in both daytime and low-light conditions. The horizontal 18" x 12" format and red-on-white color scheme ensure immediate recognition by emergency responders.

Technical Specifications

Unlike standard painted or non-reflective signs, this sign is available in three distinct 3M reflective grades — Engineer Grade, Hi Intensity, and Diamond Grade — allowing contractors to select the appropriate visibility level for the specific installation environment. The 63 mil aluminum substrate and laminated face provide a level of durability that exceeds typical adhesive or plastic sign alternatives, making it suitable for permanent exterior mounting.

Key Features & Benefits

3M Reflective Material Options

Three grades of 3M reflective sheeting are available — Engineer Grade, Hi Intensity, and Diamond Grade — enabling contractors to match sign performance to site visibility requirements. Higher-grade options provide greater retroreflectivity for low-light or high-speed approach conditions.

63 Mil Aluminum Substrate

The heavy-gauge 63 mil aluminum construction resists bending, warping, and impact damage in demanding construction and permanent installation environments. This thickness ensures the sign maintains its shape and legibility over the long term without requiring frequent replacement.

Laminated Face for Superior Durability

The laminated surface protects the reflective face from UV degradation, moisture, and abrasion, extending the service life of the sign in outdoor conditions. This is particularly important for fire protection signage that must remain legible and compliant over the life of the building.

Rounded Corners and Pre-Punched Mounting Holes

Rounded corners eliminate sharp edges that could pose a handling hazard during installation, and pre-punched holes allow for immediate mounting without additional drilling. This reduces installation time and simplifies placement on walls, posts, or standpipe assemblies.

Common Applications

Standpipe and Sprinkler FDC Identification

Clearly marks fire department connection inlets on standpipe and automatic sprinkler systems, enabling responding fire crews to locate connections rapidly during an emergency.

Commercial Building Fire Protection Systems

Used by fire protection contractors and general contractors to label FDC locations on office buildings, warehouses, retail centers, and other commercial structures as part of code-required signage.

Industrial Facility Fire Suppression Infrastructure

Suitable for permanent installation at industrial sites where fire suppression system access points must be clearly identified for both routine inspection and emergency response.

New Construction and Renovation Projects

Installed during rough-in or finish phases of construction to satisfy fire code signage requirements before certificate of occupancy inspections.
