4.5.7. Setting / Checking Alarm Latching ON / OFF
The Alarm Latching feature gives the local operator the opportunity to latch the alarm relay output in
alarm even if the sound level drops below the trigger level. The alarm latching is factory set to OFF.
Activate the MENU switch six times with the magnet-stick. The current Alarm Latching status will be
displayed (factory setting = ALOF = OFF). Activating the DOWN switch (
▼
) will switch the Alarm
Latching status to ON (ALON). Activating the UP switch (
▲
) will switch the Alarm Latching status back
to OFF. Activating the ENTER switch without changes made, switches the unit back to Normal
Operation. Activating the ENTER switch with changes made, will flash “SAVE” on the display. Confirm
the save action by activating the ENTER switch once more. Activating the MENU switch while “SAVE”
is flashing will discard the save and switch the unit back to Normal Operation. If ENTER was activated
the unit will display “DONE” to confirm that the changes have been saved and return to Normal
Operation.
The operator can change the latching settings and if desired move to the next item (Factory Default
ON/OFF) in the menu structure by activating the MENU switch straight after the change. The change
will be saved at a later stage by activating the ENTER switch at any point in the menu structure. If no
switch is activated for 60 seconds the detector will return to normal operation without saving the
changed settings.
Reset a Latched Relay
Activating an UP, DOWN, or Enter magnet will reset a latched relay. The relay will not reset if an
alarm condition is still present.
