5.2.3 Applications
The following gives typical examples for relays programmed in different modes:
-
Acoustic indicator (Mode 2): Relay active for as long as the control desk is in the
'ALARM-RECEIVED' mode.
-
System error (Mode 3 and 4): Relay active if a system error occurs.The relay can be
pulsed (0.5 sec ON) or continuous when the relay is de-energised or when the error is
reset. For example - the relay can be used to inform a technician.
-
Auto dialler (Mode 5): Relay 'active' pulse contact for alarms assigned with priority 1
or 2. In 'UNMANNED' operation the relay is energised after the relay delay time, in
'MANNED' operation the relay is activated after ALARM-RECEIVED time-out. When
switching the desk from 'MANNED' to 'UNMANNED' operation the desk sees the auto-
dialer function as if the desk is still manned for a set time (max. 20 minutes). This function
prevents a temporary 'UNMANNED' desk to immediately summon for outside help.
When the control desk operator leaves the ALARM-RECEIVED mode, the relay will not
be energised.
-
Alarm transfer (Mode 6): A relay which is programmed to operate in mode 6 can
be used to transfer an alarm to an external system.The relay will give a pulse everytime
an alarm reroute call to a colleague pager is activated.
