STI STI-HTR060T Radiant Heater with Thermostat
Overview
The STI-HTR060T is a 60-watt radiant heater module with integrated thermostat, purpose-built for lock and strike systems in access control installations. Operating at 9VDC, this unit addresses a specific deployment problem: frost buildup and thermal contraction in exterior or unheated interior access points that can lock up strike mechanisms or cause false unlatch conditions. Install this where door strikes are exposed to temperature swings below 50°F or in unheated loading docks, vestibules, and service entrances—environments where mechanical reliability depends on consistent thermal conditions.
Compatibility
The STI-HTR060T integrates with standard access control power supplies and transformer configurations that deliver 9VDC to door strike assemblies. It is compatible with strike lock architectures commonly found in professional security installations where the strike mechanism requires active thermal management. Confirm your existing strike power supply voltage before installation; this unit is designed for 9VDC systems only.
Installation Notes
Mount the heater module in close thermal contact with the strike assembly—typically inside the strike housing or in direct proximity to the latch bolt area. Wire the 9VDC supply directly to the heater terminals; the built-in thermostat cycles heating based on ambient temperature, so no external temperature sensor or control logic is required. Verify that your access control power supply has sufficient current capacity to handle the 60W load (approximately 6.7 amps at 9VDC) without voltage sag that could affect strike solenoid response time or control panel monitoring. In outdoor or high-moisture environments, use weatherproof conduit and ensure heater housing is sealed against water ingress to prevent corrosion of heating elements.
