GENERAL

This category covers electrical control units for fire-protective signaling systems in accordance with ANSI/NFPA 72, "National Fire Alarm and Signaling Code."

Products bear marking with respect to the installation environment (indoor or outdoor) and location (dry, damp or wet). Products investigated for outdoor locations, or indoor locations in ambient temperatures constantly more than 25°C are marked with the rated ambient air temperature.

A control unit consists of a unit assembly of electrical parts having provision for connection of power-supply circuits routed through the control unit equipment by a prescribed scheme of circuiting. The circuits are extended to separate devices by which the operating parts of the control units are actuated for signals and to separate or incorporated appliances by which the signals are indicated, so as to form a coordinated system combination for definite signaling services.

The Listee of a control unit furnishes the related actuating devices and signal-indicating appliances for use with the control unit or indicates the particular devices and appliances required and supplies any instructions necessary to complete their interconnection at the installation.

The individual certifications indicate that wiring diagrams have been submitted with the control unit, along with information regarding its intended application, and the unit has been tested with representative actuating devices and signal-indicating devices to be used with it as an interrelated assembly. Reference is made in the marking of the control unit to the wiring diagram showing complete information except when the installation wiring diagram is secured to the control unit.

Identification of the control unit system type is indicated in the individual certifications as:

AUX - Auxiliary System
CS - Central Station System
L - Local System
LS - Local System with Shunt-type Connection to Master Box
P - Proprietary System
PPU - Protected Premises Unit
RS - Remote Station System
RU - Supervising Station Receiving Unit

System Control Unit with Emergency Voice Communication — A system control unit with emergency voice communication consists of a control unit that employs a speaker system in lieu of conventional general alarm-indicating circuits. The control unit may also have additional provision for telephone communication by use of hand sets.

System Control Unit with Emergency Telephone Communication — A system control unit with emergency telephone communication consists of a control unit with conventional general alarm-indicating circuits and additionally employs telephone communication circuits to remote telephone hand sets for emergency communication during a fire condition, usually for use by fire department personnel.

The initiating device types that can be connected to the control unit system types indicated in the individual certifications are:

A - Automatic Fire Alarm: thermostats, smoke detectors, etc.
CO - Carbon Monoxide Alarm: carbon monoxide detectors
M - Manual Fire Alarm: manually operated boxes
SS - Supervisory: gate valves, water-level switches, temperature switches, carbon monoxide alarms, residential fire alarm control units, etc.
WF - Waterflow Alarm: waterflow switches
WSS - Watchman's Supervisory Service

The signaling types applicable for each control unit system type indicated in the individual certifications are:

C - Coded
DAC - Digital Alarm Communicator
M - March Time
MX - Multiplex
NC - Noncoded, Steady, Temporal 3 Pattern, etc.
OT - Other Transmission Technologies
PB - Performance-based Technologies
Rev Pol - Reverse Polarity
T4 - Temporal 4 Pattern
1W-RF - Radio Frequency (one-way private radio)
2W-RF - Radio Frequency (two-way private radio)

Carbon monoxide detectors interconnected with the fire alarm control unit system to produce a carbon monoxide alarm are investigated to ANSI/UL 2075, "Gas and Vapor Detectors and Sensors." Carbon monoxide alarm equipment interconnected with the fire alarm system to produce a supervisory signal is investigated to ANSI/UL 2034 "Single and Multiple Station Carbon Monoxide Alarms."

Where more than one control unit system type is indicated for a model number, such as L, LS, AUX and RS (PPU), that particular model is suitable for all the indicated applications. The change from one type to another may be made by deletion or addition of a panel or module inside the control unit cabinet or revisions to operating software to provide the additional function. In other cases a control unit may be suitable for a dual function without any panel changes.

Authorities Having Jurisdiction should be consulted before installation or revision.
