STI BPA1816 Aluminum Back Panel for Access Control
Overview
The STI BPA1816 is an 18-inch by 16-inch aluminum mounting substrate engineered for outdoor and weathered access control deployments. This back panel provides a corrosion-resistant foundation for securing reader hardware, strike components, and credential devices in environments where moisture and temperature extremes degrade standard steel or plastic mounting solutions. The EnviroArmour aluminum construction resists salt spray and UV degradation — relevant if your installation sits within 500 feet of coastal environments or receives direct sunlight 8+ hours daily. The BPA1816 supports 9VDC power distribution, making it compatible with battery-backed and hardwired access control circuits.
Compatibility
This back panel integrates with STI access control systems and reader installations that operate at 9VDC. Specific compatible models include the STI-1200, STI-1230, STI-1100, STI-1130, STI-1250, and STI-3150 series devices — refer to each device's mounting documentation to confirm frame alignment and cable entry points. The 18x16 footprint accommodates multi-reader configurations and strike assemblies typical in dual-authentication or high-traffic entry scenarios. Installation integrators should verify that target readers and strikes are rated for the same voltage environment before ordering.
Installation Notes
Mounting requires four 7mm masonry drill holes and appropriate wall anchors for the installation surface (concrete, brick, or steel stud). Position the back panel frame centrally over the devices to be protected, mark fixing hole locations, drill, and secure with the provided fasteners. For surface-mounted installations, blank off unused cable entry holes using the spacer inserts included. Select and install cable gaskets appropriate to your wiring method to maintain environmental seal integrity. Installation is straightforward for integrators familiar with standard access control panel mounting; no specialized tools beyond a 7mm drill bit are required.
