1. Introduction
The Alarm System
The 9651 alarm system comprises a control unit, one or more keypads, and
various detectors.
The control unit is a box that houses the main controller, power supply,
stand-by battery, and any remote communicator. The control unit is normally
fitted out of sight in a safe place (for example under the stairs).
The detectors are installed at various places, or
zones
, around the
premises. If something triggers a detector then the detector signals back to
the control unit. How the control unit reacts depends on whether the system
is
set
or
unset
.
When
set
the control unit raises an alarm whenever a detector is triggered.
The alarm might be a bell or strobe on the outside of your premises, or it
might be a silent signal from the communicator over the telephone line to a
recipient. When
unset
the system does not raise an alarm if a detector is
triggered.
The system provides different setting
Levels
, labeled A, B, C and D. Level A
sets the whole system, protecting all of the premises covered by the alarm
system. Levels B, C and D set part of the system, protecting part of the
premises while the rest is in use. The system raises an alarm when a
detector belonging to a set Level is triggered. The Installer allocates zones to
Levels B, C and D during installation. Ask your Installer to tell you which
zones are allocated to each Level.
Your premises may be fitted with
24 hour
zones and
panic alarm
zones. If
these zones are triggered the system will raise an alarm whether or not any
Level is set.
The Keypad
Your alarm system is fitted with a 9930 liquid crystal display (LCD) keypad.
From the keypad you can set and unset the system, read the event log and
make minor changes to the way the system operates.
You must enter an
access code
or present a “proximity tag" (simply called a
"tag" in the rest of this book) at the keypad before the system will accept
commands from the keypad. If you make a mistake with your access code
press
X
to clear the display and start again. The system can store up to 16
different access codes and/or tags, providing secure access for 16 users.
Figure 1 on the next page shows the keypad in detail.
