7.4 Alarms
7.4.1 General
There are various alarms that can be configured in the MDR. Such as speed, panic,
IO, video loss, motion detection, blind detection, G-Force, Geo-Fencing and HDD
Error. Alarms and events are different. Alarms are reported to the Centre Server
(depending on MDR model). Events are stored but do not get reported to the Centre
Server. All alarms use the alarm link setup page.
Channel
is used to choose which channels you would like the alarms to be
triggered based on. The options are 1 to 6 (4CH) and 1 to 12 (8CH).
Post Record
specifies the period of recording appended at the end of an alarm.
For instance, if a sensor is triggered for 1 sec and the alarm duration is 30 seconds
and the post recording is 15 seconds, the total amount of recording time will be 45
seconds. By default, this is 10 minutes.
Lock
represents whether an alarm cannot be overwritten by the MDR. When the
retention expires, the locked files will automatically be unlocked and deleted. Refer to
Chapter 7.2.2.1 General on how to set lock expiry timeframes.
Alarm Output Link
refers to the 2 outputs found on the IO cable. These outputs
can be activated based on a linked alarm. Enable this for a high on the alarm outputs.
Alarm Link Setup 1 Figure 79
Alarm Output Duration
represents the amount of time the alarm output will be
active for. This can be between 0 and 255 seconds.
Channel Link
can be used to display a single or quad configuration.
Panic Button Alarm Duration
is active when an external remote panel is
connected to the IO cable. This will sound the remote panel’s buzzer for the specified
time. By default, this is 0 seconds. The options are 0 to 255 seconds.
Buzzer
refers to the built-in buzzer inside the MDR docking station. Once this is
enabled the duration can be configured.
Buzzer Duration
can be configured in two ways depending on the type of alarm
being triggered. The options are ALWAYS (the buzzer will sound continuously without
interruption) or TIMER (the buzzer will sound for the defined period). Timer can be set
between 5 and 60 seconds. For example, video loss is a catastrophic failure and
Brigade suggests using ALWAYS for such an alarm.
Alarm Snap
can be enabled, the settings are based on the alarm snap link setup.
Refer to 7.3.2 Snapshots to define what a snapshot is.

7.4.1.1 Speed Alarm
Overspeed Enable
is used to activate overspeed
alarms or events.
Alarm Type
can either be alarm or event. Alarms are
saved to the Centre Server (depending on MDR model,
requires 4G/Wi-Fi)) and are displayed in the alarm log in
Live view in MDR-Dashboard 5.0 Server mode.
Events are stored but do not get saved to the Centre
Server. Events are not displayed in the live view alarm
log.
Trigger Setup
is used to control the conditions for
the trigger.
For Alarm Link Setup details refer to 7.4.1 General.
Speed Alarm Figure 81
Early Difference
is an early warning for drivers to
curb their speed. For example, if you set the speed to
70mph, and early difference is set to 5mph, then when
your speed reaches 65mph, the MDR will sound a short
beep to warn the driver. By default, early difference is
set to 10 mph.
Speed
refers to threshold value for which speed will be
considered an overspeed and recorded as an alarm.
Duration Time
specifies different lengths of time
which allow for longer/shorter alarm durations. If the
alarm duration is set to 30 seconds and a short 2
seconds alarm occurs, this would be treated as a 30
second alarm. Can be set between 0 to 255 seconds. By
default, the duration time is 10 seconds.
Alarm Off-Delay
is a period in which rapid
activations/deactivations can occur, which must be
ignored. This is applied when indicators or hazard lights
are connected to an input trigger where the off-time is
ignored. By default, this is 10 seconds.
