Zone |
A zone is a single circuit associated with an input device or group of
input devices in an alarm system. Each circuit is connected to a
separate input on the main control panel (ie a zone). A zone is usually
one movement sensor or a door sensor. |
|
PCB |
Printed Circuit Board. |
|
Area |
An area is a group of zones.
For example, you may have two sensors in your garage, and eight sensors
in your house. You might want to group these zones into 2 Areas which
can be turned on and off independently. |
|
PIR |
Passive Infra-Red detector.
This is a basic type of sensor that looks at the changes of Infra-Red
temperature in a room to determine if there is movement in the room. |
|
Quad Pir |
Quad Passive Infra-Red detector.
This is a single detector with two PIR sensors fitted in the one unit.
When one of the PIRs sensed movement, it confirms that the other sensor
has also sensed movement before it trips the alarm. |
|
Dual-Tech |
"Dual Technology" detector.
This is a single detector with a PIR sensor and microwave sensor in the
same unit. The microwave sensor work in a similar way to a 'ping' from a
submarine. In simple terms, it sends out 'pings' into the protected area
and then compares them to previously received signals. If there is a
change in signals it means something is moving in the room. It also
compares movement with the on-board PIR before it trips an alarm. |
|
Dialler |
The area on an alarm panel which is responsible for sending signals to a
user, control room or SMS gateway. |
|
SMS |
Short Message Service - available on all mobile phones |
|
SMS Gateway |
This is a hosted service which SMS enabled alarm systems ring using a
normal PSTN phone line.
The dialler connects to the gateway and transmits its signal via a modem
connection.
Once complete, the Gateway converts this signal to a SMS and transmits
it to a mobile phone number. |
|
PROX |
Prox is short for Proximity (or RFID).
Keypads and readers that are equipped with prox functionality can read a
number of wireless tags and cards. Prox cards are usually used in access
control, but with the 16Plus and 64 systems you can use them to turn the
alarm on and off. |
