Choose a mullion integrated keypad reader for narrow door frames or space-constrained installations, especially when a ruggedized option supports indoor or outdoor use. Choose a single-gang reader when the installation provides a standard single-gang location, then confirm the needed credential technologies, such as PIN, proximity, high-frequency credentials, mobile credentials, or OSDP connectivity.

Integrated keypad readers connect to an access control controller through OSDP or Wiegand wiring, allowing the system to receive keypad PINs and supported credential data. OSDP can support secure communication and, on compatible systems, multiple readers over one cable run, while Wiegand provides a common connection option for existing installations.

Before installation, confirm the reader’s required voltage, such as 12 to 24 VAC or VDC for supported keypad readers, and plan wiring for OSDP or Wiegand communication, relays, door sensors, and credential inputs as applicable. For IP-enabled units, review the site’s LAN connection and Power over Ethernet (PoE) needs, while mobile, proximity, or high-security credentials may require compatible access-control equipment.

Integrated keypad readers support indoor and outdoor access control with illuminated or backlit keys, proximity credential reading, mullion or flush-mount form factors, and, on applicable models, rugged construction for exposed installations. High-security applications can use PINs with 13.56 MHz smart credentials, 125 kHz proximity credentials, mobile credentials, and Open Supervised Device Protocol (OSDP) connectivity, with some readers supporting two-factor access.
