Honeywell 4232CBM Connected Building Access Control Module

The Honeywell 4232CBM Connected Building Access Control Module is an expansion module that links a compatible control panel to external equipment over a serial connection. It suits installers integrating building systems with third-party hardware, and it mounts inside the panel cabinet and draws its power from the panel's ECP bus. Four status LEDs make troubleshooting straightforward.

Key features

• Mounts directly inside the control panel cabinet with the included double-sided tape.
• Connects to external equipment over a three-wire RS232 or four-wire RS422 interface.
• Four status LEDs help with system troubleshooting.
• Runs on 8-12V supplied from the control panel's ECP bus.
• Draws 50mA nominal and 75mA maximum.
• Requires driver software, which is supplied separately by the third-party vendor you need to work with.
