STI KIT-H18053 Thermostat Protector Lock Kit with Two Keys

STI KIT-H18053 Thermostat Protector Lock Kit

Overview

The KIT-H18053 is a two-key lock and strike assembly designed to physically secure thermostat units and HVAC control points in commercial and industrial facilities. This kit prevents unauthorized temperature adjustments—a critical control point in multi-tenant, high-security, or regulated environments where environmental settings must be locked to authorized personnel only. The 9VDC operating voltage integrates directly into existing access control infrastructures, eliminating the need for separate power provisioning.

Compatibility

This lock and strike combination is compatible with HVAC control enclosures and thermostat housings. The kit works with HID credential reader systems and standard access control installations already deploying 9VDC power supplies. If your facility uses a different access control platform or lacks 9VDC infrastructure, verify compatibility with your integrator before ordering.

Installation Notes

Installation requires mounting the strike and lock assembly to the thermostat enclosure or wall-mounted control housing. Secure mechanical fastening (masonry or wood anchors depending on substrate) is necessary—do not rely on adhesive alone for life-safety equipment. Verify 9VDC power availability at the installation point; if running new wiring, use 18 AWG minimum and route through conduit in accessible areas. Test lock and strike engagement before final commissioning to ensure smooth operation under repeated cycles.
