Introduction

U922 comes as either a speech transceiver, for use in the teleCOURIER 900 radio
paging system, or an alarm transceiver, for use in the telePROTECT 900 alarm
system.

Transmission of speech and alarm is made in the UHF 425-475 or the VHF 140-175
MHz range. Paging and speech is received in the UHF 425-475 MHz range. The
speech transceiver can transmit and receive voice as well as text messages, allow­ing both mobile-to-central and mobile-to-mobile calls. The alarm transceiver can, in
addition to the functions of the speech transceivers, transmit different alarms. It
can also receive an acknowledgement paging confirming that the alarm has been
received.

The alarm transceiver can be equipped with a location receiver that stores the
location code transmitted by fixed LF or IR Locators. When an alarm is sent, the
location codes are also sent by the transceiver to the alarm central. Another
security function is that the alarm transceiver can be supervised continuously.

All transceivers, except those with a LF receiver, vibrator and one-way speech
transceivers without acknowledge are available in intrinsically safe versions that
comply with classification EEx ib IIC T4. The unit is water resistant according to
IP64.

• Alarm transceiver with no-speech and 6-button keypad.

• Speech/Alarm transceiver with one-way speech and 6-button keypad.

acknowledged message is erased. If all 10 messages are unacknowledged the
oldest unacknowledged message is erased. Depending on the length of the new
message several messages might be erased. The messages are also erased when
batteries are replaced.
