Cdvi Americas Ltd SETR2641AM2.B Mini Transmitter 2ch 433mhz

Product Description

The CDVI AMERICAS LTD SETR2641AM2.B is a compact two-channel wireless mini transmitter keyfob operating on the 433 MHz frequency band. Designed for access control applications, this unit sends radio frequency commands to compatible receivers, triggering door releases, gate operators, or other controlled entry points. The blue housing helps distinguish it from other keyfobs on a technician's inventory shelf. Access control installers and low-voltage security technicians are the primary trades that deploy this device in both residential and light commercial settings.

This transmitter is suited for installations where a small, pocketable remote is preferred over a wall-mounted push button or keypad. Typical use cases include pedestrian gate control, garage door operators, electric strike or magnetic lock releases, and barrier arm systems. The two-channel configuration allows a single keyfob to operate two independent outputs or two separate access points, reducing the number of remotes a user needs to carry. It ships as a single unit and is ready for pairing upon delivery.

Key Features

• Two independent channels allow control of two separate access points or functions from one keyfob
• 433 MHz operating frequency for reliable short-range RF communication
• Compact mini form factor fits easily on a keychain
• Blue housing provides quick visual identification in multi-keyfob environments
• Sold individually, simplifying single-unit replacements or add-ons

Compatibility

Designed as an OEM-style keyfob transmitter for use with 433 MHz compatible access control receivers and gate operator systems. No specific compatible model numbers were provided in the product data.

Installation Notes

Installation of this keyfob transmitter is typically performed by a licensed low-voltage or access control technician. Before pairing or servicing the associated receiver, power down the controlled access device per the manufacturer's instructions and follow applicable NEC low-voltage wiring guidelines. Program the transmitter to the receiver according to the receiver's pairing procedure. Do not open or modify the transmitter housing, as this may affect RF performance and void any applicable warranty.
