Glossary Of Terminology; Symbols Used - Ness Security Products SecurityGuardII Owner's Manual

The following is a compilation of the terminology used throughout this manual and a short explanation of the terms.
The microcomputer based SecurityGuard forms the heart of
your security system. Your Radio Key is a pocket sized device
which transmits an encoded radio signal to tell the
SecurityGuard to go into one of three operating modes; Arm,
Disarm or Home. Additionally the Radio Key can tell the
SecurityGuard to create an Emergency Alarm at any time.
Additional detection devices called Passive Infra-Red
Detectors (or P.I.R.s for short) can detect the movement of an
intruder by sensing their body heat. P.I.R.s are used to cover
various critical areas of your premises where an intruder might
enter or trespass and will transmit an encoded radio signal to
tell SecurityGuard that there is movement present.
Reed Switches are detection devices which attach to doors
and windows and are used to detect if a door or window has
opened. A Reed Switch is made up of two parts; A Magnet
which normally attaches to the moving portion of the door or
window and a Reed which detects the presence or absence of
the magnet. The Reed Switch transmits an encoded radio
signal to tell SecurityGuard that a door or window has been
opened.
Your SecurityGuard is said to be Armed or on when it allows
all P.I.R. and Reed Switches to cause a full Alarm. Your
SecurityGuard is said to be in Home mode when it allows only
selected P.I.R. or Reed Switches to cause an Alarm. This is
normally the case when you are home and wish to have part
of your alarm active and part of it inactive to allow freedom of
movement in that area. At all other times your SecurityGuard is
said to be Disarmed or off when it does not allow any P.I.R. and
Reed Switches to cause a full alarm.
When leaving your premises Arm your SecurityGuard using
your Radio Key to enable it to detect intruders and generate an
alarm. SecurityGuard will ignore detection devices for the Exit
Time to enable you to depart your premises without triggering
an alarm.
When you enter the premises the SecurityGuard will delay an
alarm for a short Entry Time. Failure to Disarm SecurityGuard
before this time will cause an alarm. Alternatively you can
Disarm from outside the premises in which case no Entry Time
is required.
An Alarm will cause the SecurityGuard Siren and External
Siren to sound. The Sirens will sound for up to 5 minutes unless
a Disarm signal is received from a Radio Key in which case the
Siren will stop immediately. An optional Strobe Light will flash
on the External Siren cover as a visible warning of an Alarm
and continue flashing for one hour.
The External Siren has an inbuilt Tamper Switch which will
cause an Alarm if an unauthorised attempt is made to
disconnect the Siren.

An Emergency Alarm or Panic can be created by pressing the
side lever on any Radio Key for 2 seconds, an Emergency
Alarm will sound the sirens in the same manner that a normal
Alarm does. An Emergency Alarm can be used to scare
intruders or alert friends or neighbours.
The SecurityGuard is fitted with a Rechargeable Battery which
will normally run SecurityGuard for around 3 to 4 months
before requiring recharging. A Battery Charger is provided
which plugs into the SecurityGuard and plugs into a standard
power point to recharge your battery as required.
The SecurityGuard displays all information by way of its Status
Display. The Status Display is a very bright, red, dual 7
segment display which it can be seen from anywhere in the
same room as the SecurityGuard and will display conditions
such as status (Armed, Disarmed etc.) and warnings such as
Low Battery etc.
At other times your SecurityGuard may have been
programmed for one or more Reed Switches or P.I.R.
Detectors sound a Chime warning. A Chime warning has a
lower priority than an Alarm and therefore the SecurityGuard
will only sound a series of beeps from it's siren. Chime can be
used for things such as front door alarms, pool gates, studies
etc.
