Johnson Controls T-4002-3004 Guard

The Johnson Controls T-4002-3004 Guard is a professional-grade, heavy-duty solution designed to provide superior surface-mounted thermostat protection for the T-4000 Series equipment. Engineered specifically for pneumatic thermostat systems, this assembly features a rugged cast aluminum thermostat guard that prevents tampering and mechanical damage in high-traffic commercial or industrial environments. The unit includes a dedicated mounting bracket, allowing for seamless horizontal or vertical mounting depending on your existing field configuration. As a veteran-preferred HVACR control accessory, the T-4002-3004 ensures the integrity of your climate control calibrations by shielding the sensitive bimetal elements of the T-4002, T-4054, and T-4100 models without obstructing proper airflow. This silver-finish aluminum casing is the standard for contractors needing to secure Johnson Controls T-4000 series instruments post-construction. Its high-durability construction resists shocks and vibrations, ensuring your sensors remain accurate and operational in demanding mechanical rooms or public hallways. Reliable, field-tested, and built for exact compatibility with JCI pneumatic controls.

• Durable Cast Aluminum Construction: Provides a rigid physical barrier against impact and unauthorized setpoint adjustments.
• Universal Mounting Profile: Optimized for both vertical and horizontal orientations to match any thermostat installation site.
• Engineered for T-4000 Series: Guaranteed fitment for Johnson Controls pneumatic room instruments, including the T-4002-201 and T-4002-202.
• Post-Construction Protection: Ideal for protecting newly installed controls in schools, hospitals, and industrial facilities.
• Integrated Mounting Bracket: Simplifies the retrofit process by including the necessary hardware for secure surface attachment.

• Is this guard compatible with non-Johnson Controls thermostats? While specifically designed for the T-4000 series, it can be adapted for other surface-mounted pneumatic thermostats featuring similar dimensions (approximately 4-13/16" L x 3-1/2" W).
• Does this guard interfere with temperature sensing? No. The design allows for sufficient airflow, ensuring the internal bimetal sensor accurately reads the ambient space temperature.
• Can it be used for both high-volume and low-volume thermostats? Yes, the T-4002-3004 guard is designated for use with both high and low-volume output pneumatic controllers within the JCI line.
