i-PRO MC-921-PTNN Black Wall Switch HID Multiclass Reader
The MC-921-PTNN is a wall-switch-form-factor multiclass reader finished in black, designed for visually clean access-control installations. It reads HID-compatible credentials including iClass SE, iClass legacy, and 125 kHz Prox cards, making it a versatile choice when a site mixes older and newer credential technology. The wall-switch profile installs flush against typical door surrounds and finishes neatly next to standard light switches and other building hardware.

The wall-switch reader form factor matters in installations where appearance is part of the spec. Boutique hotels, corporate headquarters, healthcare administration suites, and high-end residential entrances frequently reject the larger industrial reader bodies in favor of a wall-switch profile that disappears into the door surround. The MC-921-PTNN delivers the same credential performance in a form factor that complies with these aesthetic requirements.
Configure the reader for the credential mix the site actually uses. If the customer is still operating 125 kHz Prox alongside newer iClass SE deployments, multiclass support means a single reader can carry the program through the migration period instead of requiring two readers per door. Confirm reader-to-panel cable length is within Wiegand specifications (or use an OSDP-capable variant if available), and isolate the reader chassis ground from the door frame to avoid ground loops on long runs.
