Pre-Signal
The panel is equipped with a means of setting up a Pre-signal where the operation of an automatic detector or initial operation of
manual station will only activate selected devices for the purpose of notifying key personnel who then have the option of initiating a
general alarm. Any subsequent actuation of an alarm initiating device from a different zone on the system will result in the activation
of a general alarm.
Pre-Signal Setup
Below is just an example of how pre-signal can be achieved on a Velocity MMP system. Ensure that when pre-alarm operation is used,
that it complies with UL864 10
th
Edition requirements.
Go to the engineer menu, and select the
‘Cause/Effect’ icon.
The cause and effect table screen will be shown.
Press the
button to create a new cause and
effect.
The first cause and effect that will need to be
programmed is to turn on a NAC appliance that will
notify key personnel during any alarm signal
(normally located in the same room as the panel).
For this example we will use a VDOT-SB
(Addressable Sounder base)
at address Loop:1
Point:1
For more information on how to add cause and
effects, refer to the Cause and Effect Section.
NOTE:
PRE-SIGNAL shall only be used when the panel is constantly monitored by an Operator.
