STI KIT-7500-HTR Replacement Heater
Overview
The KIT-7500-HTR is a direct-replacement heating element for STI-7510 and STI-7511 series electronic locks. If a lock's thermal performance has degraded or you're restocking spares for a multi-door access control system, this component restores reliable operation in temperature-sensitive deployments. Operates at 9VDC and integrates into wired access control architectures supporting TCP/IP and RS-232 communication protocols.
Compatibility
This heater is engineered exclusively for the STI-7510 and STI-7511 lock series. Before ordering, confirm your installed lock model matches one of these two series — cross-compatibility with other STI electronic lock families is not supported. Verify your system voltage is 9VDC before installation.
Installation Notes
Installation during initial lock setup or when restoring thermal performance in existing systems is recommended. This is a wired component — ensure power and control wiring are secured according to your access control system documentation. No special tools are required beyond standard wiring connectors and a multimeter to verify 9VDC supply at the lock terminals.
