UHF Key Ring Transmitter

20-86 Series

The 20-86 is an extremely small, high specification, key ring, or pendant paging transmitter capable of transmitting text directly to pocket pagers. Ideally suited to retail assistance, rest/care home emergency applications or duress environments.

The 20-86 series is an extremely small, IP67 rated, high specification keyring or pendant POCSAG paging transmitter, available with 1 to 5 buttons as required. Powered by a standard CR2032 coin cell.

It is small, comfortable and discreet and can be hand-held, kept on a key ring, held in the pocket or worn on a lanyard around the neck.

A front panel LED is used to confirm a message is being sent and/or to indicate a flat battery.

The Salcom "Stuck Button" feature prevents the battery going flat if a button has been accidentally held on.

20-86's has a receiver which can be used, with appropriate transceivers, to provide visual message received acknowledgements.

The 20-86 range of products are POCSAG direct to pager transmitters, allowing low cost systems to be developed since intermediate receivers and transmitters are not required for short range applications.

20-86 transmitters support up to 5 inputs, each of which can be programmed with up to a 35-character message. Programming can be either with a serial programming cable that can be purchased separately or pre-programmed when supplied. Once operating frequency has been set the 20-86 messages can be changed using programming software with an optional programming lead.

Although the 20-86 is a low power transmitter, a direct line of sight transmission range of up to 200 metres can be expected. Transmit range within buildings is reduced, but still considerable having proven to be effective in some cases between floors and across buildings.
