Definition
Addressable Sensors
Smoke and temperature sensors that convert analog values read at the
sensor head and communicate the values back to the classic 2000 Mk II
control panel.
Class A
An initiating device circuit characterized by the use of four conductors: two
feed lines, and two return lines.
Class B
An initiating device circuit characterized by the use of two conductors and
an end-of-line device, usually a resistor.
Contact Monitor Module
Addressable device that monitors a normally-open fire alarm initiating
device. (AKA: Switch Monitor Module)
Input Point
An addressable sensing device, such as a smoke or heat sensor, monitor
module, ZFZA module, ZTZB module, or ZDIO input.
Input/Output Module
Addressable device that allows the control panel to selectively activate a
relay output. May also be used as an input.
Isolator Module
Module that permits a group of sensors and modules to be electrically
isolated from the remainder of the SLC.
Loop
A group of devices attached to one line originating from and returning to
the main device.
Mapping
Process of specifying which outputs are activated during certain
system events.
Network/Serial Devices
Four-wire devices connected over an RS-485 network. Two wires
are required for 24VDC power and two for network communications.
Output Group
A group of output points where the operating characteristics are common
to all points in the group.
Output Pattern/Cadence
Pattern that output will use (i.e., continous, march time, or temporal 3).
Applicable to NACs.
Output Point
A notification point or circuit for notification appliances, or relays.
Sensor Bases
Mounting base for analog sensors that contain an addressing card.
Sleep Mode
An energy conserving mode in the event of a loss of AC power.
Sounder Output Module
Module that controls and supervises compatible 24VDC
notification appliances.
Switch Monitor Module
Module that allows the control panel to monitor normally-open fire
alarminitiating devices, such as manual pull stations, and waterflow and
tamper switches. (AKA: Contact Monitor Module)
Watchdog Circuit
System circuit that verifies microprocessor is functioning correctly.
