Note that the installer can disable these LEDs in order to hide the
state of the system (to comply with EN50131). Alternatively, the
installer may have programmed the LEDs to glow for 30s
immediately after setting, and then to go out.
Detectors or Zones?
When talking about alarm systems, people tend to use the words
“detectors” and “zones” interchangeably. Most of the time this
doesn‟t matter, but occasionally it can cause some confusion. In
this book a “detector” is a physical piece of equipment that
signals some event. A “zone” is how the keypad reports the
location of the detector.
Users
Types of User
The control unit provides for seven different types of user:
Master User This user can add other users to the system, edit
them, or remove them. There is always (at least) one master
user: User 001. Master users can create all other user types,
including other master users. No user can remove User 001 or
change their type.
Normal User This user cannot add or delete other users. A
normal user can change their own access code, switch the Chime
function on and off, and operate any outputs that the installer has
made available.
Guard A guard can only unset a partition in alarm, reset it, and
then set the partition again. A guard cannot change their access
code.
Set Only This type of user can set the system, but cannot unset
the system. A set only user cannot change their access code.
Duress Code A duress code is similar to a Normal User, but
whenever a user sets or unsets the system with a duress code
the control unit notifies the alarm receiving centre. The Installer
must program your system to provide this feature, and you must
agree with your alarm installer and the ARC what action the ARC
should take on receiving a duress message.
