12-86-0000 Key Ring Transmitter

440-470MHz extremely small direct to pager keyring or pendant paging transmitter, ideally suited for retail and rest home assistance applications.


Ideally suited to retail assistance and rest home emergency applications, the 12-86 is an extremely small, high specification, key ring or pendant paging transmitter capable of transmitting text directly to pocket pagers.

Using an appropriate receiver, the 12-86-0000 can also be used for any general remote control applications such as turning on lights, disabing alarms etc.

Each pendant is available as a one, two, three, four or five button transmitter, all at the same price. Please specify your button configuration preference when ordering.

Powered by a standard CR2032 coin cell, the transmitter will operate for more than one thousand transmissions under normal conditions before needing replacement.

The 12-86 range of products can send text messages directly to paging receivers, providing simpler, lower cost systems since intermediate receivers and transmitters are not required for short range applications.

Any button on the unit can be programmed with a unique message, whether for display on a pocket paging receiver, or for control purposes. 

To achieve this, free programming software is available for download from the Salcom website (www.salcom.com), although the units can be supplied from the factory pre-programmed with the required messages.

Utilising the software, the 12-86 can be programmed serially by using a programming cable (part No. 12-47-0000).
