Common Installations
This chapter presents a list of common installations. It explains the various factors you might wish
to consider for each installation, and directs you to the parameters you need to adjust.
Installing movement detectors
You may need to install movement detectors for inactivity monitoring and intruder detection. If
properly configured, movement sensors, such as PIRs and pressure mats, can be used for both
intruder detection and inactivity monitoring. You might wish to consider the following:
1.
Lifeline 4000 can be made to beep every time it receives a trigger from a movement sensor.
This facility is only intended for installation, and can be set using parameter 48 (see
Intruder
Monitoring
on page 57).
2.
Register a movement detector with the Lifeline 4000 before you attach it to a wall, ceiling
or floor. For example, if you wish to use a PIR movement detector you should register it
prior to drilling holes in a wall to mount it. This can save time if the PIR is faulty. More
importantly, you should test that the Lifeline 4000 can receive radio signals from the PIR
when the PIR is in position (but before you have drilled any holes). If a thick concrete beam
or metal cabinet is between the PIR and the Lifeline 4000 then there is a chance that the
radio signal will not get through, and you will have to select a different place to mount the
PIR.
3.
If you are installing several movement detectors then consider registering these triggers as
Extension Radio Triggers
rather than as triggers in the predefined parameters. The advantage
of
Extension Radio Triggers
is that they can also contain location information (see page 38),
which can be particularly useful in dealing with alarms and identifying the cause of repeated
false alarms.
4.
Do not register a movement detector as an intruder trigger. Intruder triggers are the sorts
of sensors that detect whether a pane of glass has been broken. A movement sensor
registered as a movement detector is more flexible—it can be used for both inactivity
monitoring and intruder detection (see the section on
Trigger Types and Actions
on page
44). You also have the option of registering it as an Entry/Exit type of movement sensor,
which provides time for arming and disarming an intruder alarm.
