ADPRO FastTrace by Xtralis Installation and User Manual
Doc 11168_12 83
Alarm Input Type
Options: Normally Open (N/O), Normally Closed (N/C), N/O SEOL, N/C SEOL, N/O
DEOL, N/C DEOL
Default: Normally Open
The FastTrace can be programmed to trigger an alarm when the contacts associated with a
channel change state. This may be when:
• a normally closed contact changes its state to open, or
• a normally open contact changes to close
The alarm inputs may be supervised to detect tamper (attempting to override the alarm contacts
by a cut or short) with either a SEOL (Single End of Line) or a DEOL (Dual End of Line) wiring
hierarchy in conjunction with N/O or N/C sensor contacts.
Depending on the alarm wiring strategy, SEOL termination is used to detect either a short circuit
on a line or on an open circuit, while DEOL is used to detect both short and open circuit
conditions.
Hold Time
Options: When active, 2 sec, 5 sec, 10 sec, 30 sec, 60 sec.
Factory Default: 10 seconds
When there is a requirement that two (related) alarm inputs must be active before an alarm event
is activated (known as double knock alarm activation), the Hold Time option sets the time
‘window’ for the second alarm input to occur. Event combinations are defined in the Operational
Behaviour section.
If the second alarm input is not activated within the Hold Time period, no alarm event will be
generated. Choose the value most suited to the alarm activation requirement.
Note: If the alarm input activates multiple times within the hold time period, only the first
alarm will be reported to the CMS, but all activations will be recorded to the
database for future retrieval.
Camera View Style for the Triggered Alarm
Options: Live, Quad, Duress
Factory Default: Quad
When an alarm is triggered by these contacts, the style of display configuration shown on
VideoCentral can be preset.
Note: Stored alarm images are only associated with Quad and Duress alarm types.
The Live option is primarily designed for use with access (entry/exit) points. A live video feed is
displayed at VideoCentral.
The Quad option captures three alarm images in a user-defined period (defined under Camera
Settings/General tab) and displays the images at VideoCentral, along with a fourth pane which
sequences through the three images to highlight movement.
Warning: When using Duress alarms, ensure the General Alarm Relay is not set
to ‘On Connection to Site’ if it is linked to a horn or light etc, as this will
trigger when a Duress alarm occurs (refer to General Alarm Relay
Settings on page 71).
