DICTIONARY OF THE TERMS
ATS
(Alarm Transmission System) – A special type of user account which is a monitoring
station authorized with the device main access code.
P1, P2
– denote Partition 1 and Partition 2, respectively, which are the areas monitored by
their assigned zones (detectors).
AES
(Advanced Encryption Standard) – An advanced symmetric key encryption block cipher,
currently among the most popular encryption methods. AES was published in 1997 by
Vincent Rijmen and Joan Daemen and accepted as an encryption standard by the U.S.
government in 2002.
NO
– A configuration type of the input zone which enables detection of two states: normal
(standby), in which the NO relay is open, and alarm (breach), in which the NO relay is
closed.
NC
– A configuration type of the input zone which enables detection of two states: normal
(standby), in which the NC relay is closed, and alarm (breach), in which the NC relay is
open.
EOL
– A parametric configuration type of the input zone which enables detection of three
operating states with a 2.2 kΩ parametric resistor: normal (standby), alarm (breach), and
failure.
DEOL
– A two-parametric configuration type of the input zone which enables detection of
four operating states with two 1.1 kΩ parametric resistors: normal (standby), alarm
(breach), tampering, and zone failure (e.g. by shorting of wiring).
TEOL
– A configuration type which doubles the input zone by enabling connection of two
zone detectors to a single input terminal of an alarm control panel. In this configuration, the
source detector of an alarm signal is identified; the tamper input is common for both
detectors. Each detector in this configuration requires two resistors.
Chirp
– A short sound output by an alarm siren connected to one of the OUT terminals of
an alarm control panel. There can be one chirp or a series of chirps.
RS-232
– A serial data communication standard. It is used for data exchange between
hardware units over COM ports.
TAMPER
– An anti-tamper switch, the tripping of which indicates an intentional disruption
of operation of an alarm system, e.g. by opening the cover of a detector.
Clock loss
– An event which indicates that the RTC has been reset. It is generated when an
alarm system is powered on after a power cycle.
Alarm history
– A list of all past and currently inactive alarms logged in an alarm system.
Watchdog
– A feature which enables an automatic reaction of an alarm device when its
connection to a monitoring station is lost.
