alarm signal - an alarm signal lets people know the alarm system has activated. The alarm signal may
be a bell, siren, or visual device (local alarm), or it may be a message transmitted to a central station
alarm company on leased telephone lines or the switched network. Every alarm system must have an
alarm signal.
alarm silence - a keypad menu function that allows authorized users to silence alarm bells or sirens
during an alarm condition on the system. Users can also enter their user code and press the command
key directly from the status list. This is an exclusive function of DMP panels that allows silence of
alarm bells without disarming the system.
alarm system - a combination of compatible initiating devices, control panels, and notification
appliances designed and installed to produce an alarm signal in the event of emergencies.
all/perimeter - a panel mode of operation that provides for the system to be configured into just two
areas: a perimeter and an interior. Exterior doors and windows are assigned to the perimeter while
inside PIRs, doors, or pressure mats are assigned to the interior area.
alphanumeric - term used to describe letters and numbers together.
ambush - a silent, invisible alarm signal sent to the central station that indicates a user is being
forced to disarm the system. The ambush code is sent when ambushed is programmed as YES in the
panel and a code for user number one is entered at the keypad. DMP panels use a unique ambush code
number to prevent false alarms.
ambush code - a special code entered into a digital keypad to indicate a duress condition that directly
threatens the user. This code does not activate signaling devices at the premises.
ambush output - a panel output that is programmed to activate any time an ambush code is entered
at a keypad. The output is turned off using the sensor reset option from the user menu. This output
is used to lock down areas or activate strobes, etc.
American National Standards Institute (ANSI) - a federation of trade, technical, professional
organizations, government agencies, and consumer groups that coordinates standards development,
publishes standards, and operates a voluntary certification program.
American Standard Code for Information Interchange (ASCII) - a commonly used coding scheme that
uses eight bits of data to encode alphanumeric and special control characters. Common to most
computer platforms.
analog - a method of data transmission where the data is continually modulated to represent
transmitted information.
annunciator - a keypad or other lighted or audible display at the protected premise that indicates the
condition of the system, zones, and armed status.
anti-passback - a programming option that requires a user to properly exit (egress) an area they have
previously accessed. If they fail to exit through the proper card reader location they will not be
granted access on their next attempt. Also, see egress.
any bypass - a panel programming feature that allows low level users to bypass zones during the
arming sequence without having to enter a higher level user code.
area - part of a protected premise that is programmed to operate separately from the other areas.
Areas can have their own keypads, zones, account numbers, and arming and disarming schedules.
area arming - a panel mode of operation that provides for one or more areas to be individually armed
and disarmed.
area schedules - a programming option that allows you to automatically arm and disarm areas within
a system. This is done by entering schedules in the panel programming.
