Man-down/No-movement alarm
Press and hold the hot-key number 1 to set the Man-down alarm or No-movement
alarm. Press OK to toggle between On/Off. When the alarm function is switched
on, the hot-key number is displayed in the display window.
Pull-cord alarm
Attach the Pull-cord to the alarm transceiver. Press and hold the hot-key number 2
to activate the alarm. Press OK to toggle between On/Off. When the alarm func-
tion is switched on, the hot-key number is displayed in the display window. Make
sure that the clip of the Pull-cord is safely attached. If the Pull-cord is pulled off, a
silent alarm will be transmitted.
NOTE: To remove the Pull-cord without triggering an alarm, the Pull-cord alarm
must be switched off.
Acknowledge
An Acknowledge is a response either to or from the transceiver. It indicates that
the message or alarm has been received and processed. When a transceiver has
sent an alarm, it can receive an acknowledgement from the fixed equipment
confirming that the alarm has been acknowledged by someone. This is called
Technical Acknowledge. The response is sent as a paging. The paging is generated
manually or automatically via an alarm module or an alarm computer and usually
includes a text message.
A paging with a request for manual acknowledgement is indicated by the symbol
“
A
“ which appears at the bottom of the display. The symbol remains until the OK
button is pressed. When it is pressed, an acknowledge response is sent to the fixed
equipment.
Supervision
The telePROTECT 900 software application PCPRO has an automatic supervision
function to check the transceivers. A paging is transmitted at regular intervals. The
paging contains a request for automatic acknowledgement from the transceivers,
but it is not presented for the user. If a transceiver does not respond to the paging
within a preset time, this will be presented as a system alarm. If the transceiver is
equipped with a location receiver, its latest known location can be presented as
well.
In addition to the supervision function, the system can be programmed to perform
a self check as follows: The user is requested to send a test alarm when the trans-
ceiver is taken out of the charging rack. If he does not, he will receive a second
request from the system as a paging. If the request does not reach the transceiver,
or the user still does not activate a test alarm, this will be registered as a system
error by PCPRO.
