Operator Mode
Master and Monitor Mode
A system operator can place any room unit in Master or Monitor mode, in order to
receive and/or initiate an alarm call. In both modes the LCD display becomes active
and will display details of received alarm calls.
Master mode In Master mode the operator is able to answer alarm calls and to
initiate calls, by using the keypad. In order to prevent conflicting
commands from several operators, only one room unit at a time can
be in Master mode.
Monitor mode In most cases Master and Monitor mode are indistinguishable to the
operator. Whenever keypad commands are made on a Monitor
mode room unit, the system will automatically upgrade the room unit
to Master mode in order to carry out the command. Only if the
current Master is in use at the time (ie locked) will this action be
inhibited. A Master becomes locked, whenever speech is in progress
and also for a short period of time immediately after the unit was
made a Master.
There is no limit to the number of Monitor units on a system, however, a maximum of
4 (including the Master unit) can sound an alarm tone simultaneously, fitting an A200+
(AllCall Amplifier) avoids this limit (see installation manual).
In Master and Monitor mode the over-door presence lamp (if fitted) will be illuminated.
Gaining Access to Master or Monitor Mode
In order to gain access to operator functions the operator must make use of one of the
M200+ units and enable it as a Master or Monitor. This can be accomplished by
pressing the
m
key and then, if required, typing an access code (this can be 1 to 4
digits). The access code may be changed as required (refer to the Installation Manual)
