OCB-AH-801J: Universal 433MHz Wireless to Hardwired Relay Interface Module

In commercial and residential intruder alarm retrofits, integrating modern wireless perimeter barriers, beam sensors, or panic buttons into legacy hardwired control panels often presents compatibility challenges. The OCB-AH-801J is a specialized signal converter designed to bridge wireless RF perimeter detectors with hardwired control panel zones across all major security brands.

1 Wireless RF Input to 1 Dry Contact Relay Output

The OCB-AH-801J receives 433MHz wireless radio signals transmitted by active infrared barriers, PIR sensors, or door contacts and instantly converts them into a clean physical relay contact state change. Featuring a single-channel SPDT (Form C) output, it provides both Normally Closed (NC) and Normally Open (NO) voltage-free dry terminals, allowing direct connection to hardwired zone inputs on panels from manufacturers such as Honeywell, DSC, Bosch, Hikvision, and Paradox.

Universal Control Panel Compatibility & Compact Enclosure

By converting RF transmissions into physical hardwired contact closures, the OCB-AH-801J eliminates the need to replace existing wired control panels when expanding a security system with wireless perimeter protection. Housed in a compact, durable enclosure with internal terminal blocks, the module operates on a standard 12VDC auxiliary power supply and includes onboard LED diagnostic indicators for signal reception and relay status verification.
