CONTROL UNIT LIMITATIONS
This control unit will not show an alarm condition without compatible initiating devices (smoke detectors,
etc.) and notification devices (horn, lights, etc.) connected to it. Electrical ratings of the initiating and
notification appliances must be compatible with the electrical ratings of the control unit and must be
properly interconnected. The wiring used for interconnection must be large enough to carry the total
current by all appliances without excessive voltage drop.
This control unit must be connected to a dedicated primary electrical source that has a high degree of
reliability and adequate capacity for this control unit. The only means of disconnecting this power source
shall be available only to authorized personnel and clearly marked “Fire Alarm Circuit Control.”
This control unit must also have connected to it, a battery set (24V) that has enough capacity to properly
operate the system for 4, 24 or 60 (depending on system type) hours standby and 5 minutes alarm per
NFPA 72 (chapter 1). These batteries do lose capacity with age. Batteries must be replaced when they
fail to provide the control unit with the required standby and alarm power or after 4 years, whichever
happens first. These batteries must be checked for performance at least two (2) times per year or more
often if local requirements dictate it.
Fire alarm control units cannot last forever. Even though this control unit was made to last for the
expected life of the Fire Alarm Systems, any part could fail at any time. Therefore, a regular test program
should be followed and documented to make sure that each part of the system is tested as per Chapter 7
of NFPA 72 or more often if dictated by local code requirements. Units that have malfunctioned must be
replaced or repaired immediately by factory authorized service personnel.
Note: This control unit is designed to show an alarm condition when the initiating devices connected to it
detect specific conditions. These conditions may or may not represent a life threatening condition (i.e.,
burnt toast may not be a life threatening condition but may cause an initiating device to indicate an alarm
condition). Also, evacuation of a building or area may unnecessarily subject individuals to an
unnecessary hazard. Therefore, it is most important that building owner, manager or representative
promulgate, distribute and/or post instructions describing steps to be taken when the fire alarm control
unit signals an alarm condition. These instructions should be developed in cooperation and conformance
with representatives of the local authority having jurisdiction.
As a backup or precautionary measure, it is strongly suggested that one of these steps should be to notify
the local fire department of an abnormal condition even where the city tie option (or similar device) is
included in the system.

1.1. DESCRIPTIONSDESCRIPTIONS
The 15073 is a notification and auxiliary power expander that provides up to 6 amps of 24 volts for
powering notification appliances and auxiliary devices. The 15073 provides its own AC power
connection, battery charging circuit, and battery connections. Used with a fire alarm control unit, this
enables you to connect and distribute power to many more devices than your control unit may normally
allow.
1.1 GENERAL DESIGN FEATURES
Inputs
The 15073 has two optically isolated inputs that provide the connection from the fire alarm control unit
notification appliance circuit to the 15073. The inputs also provide a connection for returning a trouble
condition to the control unit NAC.
The fire alarm control unit supervises its notification appliance circuit used for communicating with the
15073 the same way it supervises ordinary notification appliance circuits. The inputs on the 15073
monitor the polarity of the voltage coming from the fire alarm control unit’s notification appliance circuits to
determine when to operate the notification appliance circuit outputs. The 15073 emulates the trouble
behavior of a notification appliance circuit by opening the EOL supervision current for trouble conditions.
Note that the 15073 will sense the polarity of the fire alarm control unit’s notification appliance circuits to
drive the outputs whether or not the supervision connection is intact.
The following situations will open the EOL supervision at the inputs indicating a trouble condition:
No or Low AC power.
No and Low battery condition.
Ground fault to the output wiring.
Auxiliary Power Supply output over-current condition.
NAC output open, shorted and over-current condition on outputs associated with its input.
Notes:
If input 1 controls all four outputs, a fault on any output will cause input 1 to indicate trouble. The fault
does not affect input 2.
If input 1 controls outputs 1 and 2, and input 2 controls outputs 3 and 4, a fault condition on output 3 or 4
will cause input 2 to indicate trouble. The fault does not affect input 1.
Once the inputs are driven with forward polarity to activate the outputs, the fire alarm control unit will not
be able to sense trouble conditions through its notification appliance circuit connected to the 15073 input
circuits. Use the 15073 trouble relay when it is necessary to monitor trouble conditions and active alarm
conditions at the same time.
Notification Appliance Circuit Outputs
The 15073 has four dedicated, power-limited, NAC outputs that can be configured as two Style Z (Class
A) or four Style Y (Class B) circuits.
The 15073 provides three configuration options that will drive outputs as slaves that will follow the input or
if the inputs are on constant as ANSI temporal code or Sync strobe/horn operation.
Each of the four outputs is rated at 3 amps, though you can only draw a total of 6 amps from the 15073
outputs. The yellow Output LEDs (DS1-DS4) will indicate an open, shorted or over-current condition on
its associated NAC Output.
firealarmresources.com

15073 OWNER’S MANUAL
447179 Issue 1 Rev. A 2
You can select which input controls which output, and which inputs are Style Z (Class A) and Style Y
(Class B) using the 10 position DIP switch on the printed circuit board. Refer to Section 5 for DIP switch
settings.
Auxiliary Power Output
The 15073 has a dedicated, power-limited, auxiliary output that can be configured in two different ways.
The auxiliary output can either be non-resettable (always on), or configured to switch off when the AC
power goes off to conserve the battery standby power. When the auxiliary power is configured to switch
off, there is a 30-second delay before the auxiliary power is turned off after the AC power goes off.
The Auxiliary Power Output is rated at 3 amps. Only a total of 6 amps maximum can be drawn from the
15073 outputs. The yellow Aux PS LED (DS5) will indicate an over-current condition on the output.
Trouble Relay
The 15073 includes a form C trouble relay that will de-energize for the following trouble conditions:
No or Low AC power.
No and Low battery condition.
Ground fault to the output wiring.
Auxiliary Power Supply output over-current condition.
NAC output open, shorted and over-current condition.
Battery Charging and Supervision
The 15073 provides a battery charging circuit for charging sealed lead-acid batteries. The unit also
supervises for no and low battery conditions.
Ground Fault Detection
The 15073 monitors for ground faults to the output wiring. When detected, the unit lights the yellow
GRND LED (DS6) and de-energizes the trouble relay and the input supervision relays.
Environmental
All hardware is suitable for use in an interior or protected location.
Power Limiting
The AC power and battery wiring are not power limited. All other circuits leaving the control unit are
power limited, provided the proper installation rules are maintained.
Transient Protection
Transient protection devices are provided where needed to meet the requirements of UL864.
1.2 REGULATORY STANDARDS
The 15073 meets the requirements of industry and government regulatory agencies as noted.
Federal Communications Commission
The 15073 meets the class A requirements of the Code of Federal Regulations (CFR 47), Part 15,
subpart J, for electromagnetic field emissions.
Underwriters Laboratories
The 15073 control unit is listed under UL Standard 864 for compliance to NFPA Standard 72 for fire
service.

2.2. INSTALLATIONINSTALLATION
CAUTIONS:
It is recommended that the printed circuit boards be removed for any procedure that may
cause dust, metal shavings, grease or any such matter that may affect the circuit boards
and/or parts.
There may be several sources of power into the control unit. Each source must be
disconnected prior to installing or connecting or disconnecting wiring.
Each output circuit is rated at 3 amps. DO NOT OVERLOAD. Overloading a circuit will
cause it to shut down (power limit).

2.2 CONTROL UNIT MOUNTING
The fire alarm control unit must be mounted in a properly accessible location as required by applicable
codes. Any auxiliary battery box or other accessory not connected through a protective device or a circuit
designed for remote connection must be within the same room and connected through electrical conduit.
Installation is to be done only by qualified personnel who have thoroughly read and understood these
instructions.
When mounting on interior walls, use appropriate screw anchors in plaster. When mounting on concrete,
especially when moisture is expected, first attach a piece of ¾-inch plywood to the concrete surface.
Attach the 15073 to the plywood.

2.3 WIRE ROUTING
Notes:
All high voltage and non-power limited wiring must be kept separate from power limited
wiring. A ¼” separation must be maintained, with high voltage and non-power limited
wiring running in separate conduit openings from power wiring.
To avoid induced noise (transfer of electrical energy from one wire to another), keep
input wiring isolated from high current output and power-limited wiring. Improper wiring
installation may cause improper operation. Avoid pulling one multi-conductor cable for
the entire system. Instead, separate high current input/output from low current.
Wiring within the cabinet should be routed around the perimeter of the cabinet. It should
not cross the printed circuit board where it could induce noise into the sensitive
microelectronics or pick up unwanted RF noise from the switching power supply circuit.

2.5.6 Trouble Relay
The 15073 board has a Form C trouble relay built into terminals 7-9 of TB2. The trouble relay will de-
energize under a trouble condition.
A typical application of the trouble relay is to connect the 15073 normally closed (N.C.) contacts in series
with an EOL of a spare IDC or NAC or monitor input from a fire alarm control unit. This will cause a
trouble on the fire alarm control unit when the 15073 opens its trouble contacts.
Note: The N.C. contact is the relay contact that is closed when the 15073 has power and there are no
trouble conditions.
