Installation Procedure
Adherence to the following will aid in problem-free installation with long-term reliability:
Installation Precautions - Adherence to the following will aid in problem-free installation with long-term reliability:
WARNING - Several different sources of power can be connected to the fire alarm control panel. Disconnect all sources
of power before servicing. Control unit and associated equipment may be damaged by removing and/or inserti ng card s,
modules, or interconnecting cables while the unit is energized. Do not attempt to install, service, or operate this unit until
manuals are read and understood. CAUTION - System Re-acceptance Test after Software Changes: To ensure proper
system operation, this product must be tested in accordance with NFPA 72 after any programming operation or change in
site-specific software. Re-acceptance testing is required after any change, addition or deletion of system components, or
after any modification, repair or adjustment to system hardware or wiring. All components, circuits, system operations, or
software functions known to be affected by a change must be 100% tested. In addition, to ensure that other operations are
not inadvertently affected, at least 10% of initiating devices that are not directly affected by the change, up to a maximum
of 50 devices, must also be tested and proper system operation verified. This system meets NFPA requirements for
operation within the range of 0°C-49°C (32°F-120°F) or humidity within the range of 10%-93% at 30°C (86°F) noncondensing. However, the useful life of the system's standby batteries and the electronic components may be adversely
affected by extreme temperature ranges and humidity. Therefore, it is recommended that this system and its peripherals be
installed in an environment with a normal room temperature of 15-27º C/60-80º F . Verify that wire sizes ar e adequate for
all initiating and indicating device loops. Most devices cannot tolerate more than a 10% I.R. drop from the specified device
voltage. Like all solid state electronic devices, this system may operate erratically or can be damaged when subjected to
lightning induced transients. Although no system is completely immune from lightning transients and interference, proper
grounding will reduce susceptibility. Overhead or outside aerial wiring is not recommended, due to an increased
susceptibility to nearby lightning strikes. Consult with the Technical Services Department if any problems are anticipated
or encountered. Disconnect AC power and batteries prior to removing or inserting circuit boards. Failure to do so can
damage circuits. Remove all electronic assemblies prior to any drilling, filing, reaming, or punching of the enclosure.
When possible, make all cable entries from the sides or rear. Before making modifications, verify that they will not
interfere with battery, transformer, or printed circuit board location. Do not tighten screw terminals more than 9 in-lbs.
Over-tightening may damage threads, resulting in reduced terminal contact pressure and difficulty with screw terminal
removal. fire alarm control panels contain static-sensitive components. Always ground yourself with a proper wrist strap
before handling any circuits so that static charges are removed from the body. Use static suppressive packaging to protect
electronic assemblies removed from the unit.
Follow the instructions in the installation, operating, and programming manuals. Th ese instructions must be followed to
avoid damage to the control panel and associated equipment. Fire Alarm Control Panel (FACP) operation and reliability
depend upon proper installation.
While installing a fire alarm system may make lower insurance rates possible, it is not a substitute for fire insurance! An
automatic fire alarm system - typically made up of smoke detectors, heat detectors, manual pull stations, audible warning
devices, and a fire alarm control with remote notification capability - can provide early warning of a developing fire. Such
a system, however, does not assure protection against property damage or loss of life resulting from a fire. Any fire alarm
system may fail for a variety of reasons: Smoke detectors may not sense fire where smoke cannot reach the detectors such
as in chimneys, in walls, or roofs, or on the other side of closed doors. Smoke detectors also may not sense a fire on
another level or floor of a building. A second floor detector, for example, may not sense a first floor or basement fire.
Furthermore, all types of smoke detectors, including ionization and photoelectric types, have sensing li mitations. No type
of smoke detector can sense every kind of fire caused by carelessness and safety hazards like smoking in bed, violent
explosions, escaping gas, improper storage of flammable materials, overloaded electrical circuits, children playing with
matches, or arson.
IMPORTANT! Smoke detectors must be installed in the same room as the control panel and in rooms used by the
system for the connection of alarm transmission wiring, communications, signaling, and/or power. If detectors are not so
located, a developing fire may damage the alarm system, crippling its ability to report a fire. Audible warning devices
such as bells may not alert people if these devices are located on the other side of closed or partly open doors or are located
on another floor of a building. A fire alarm system will not operate without any electrical power. If AC power fails, the
system will operate from standby batteries only for a specified time. Rate-of-Rise heat detectors may be subject to
reduced sensitivity over time. For this reason, the rate-of-rise feature of each detector should be tested at least once per
year by a qualified fire protection specialist. Equipment used in the system may not be technically compatible with the
control. It is essential to use only equipment listed for service with your control panel. Telephone lines needed to transmit
alarm signals from a premise to a central monitoring station may be out of service or temporarily disabled. The most
common cause of fire alarm malfunctions, however, is inadequate maintenance. All devices and system wiring should be
tested and maintained by professional fire alarm installers following written procedures supplied with each device. System
inspection and testing should be scheduled monthly or as required by national and/or local fire codes. Adequate written
records of all inspections should be kept.

Model 5104B Installation Manual 151053-L8
3.3 Wiring Specifications
Induced noise (transfer of electrical energy from one wire to another) can interfere with telephone
communication or even cause false alarms. T o avoid induced noise, follow these guidelines:
• Isolate input wiring from high current output and power wiring. Do not pull one multi-conductor cable for
the entire panel. Instead, separate the wiring as follows:
High Voltage AC Power
Audio input/output Phone Line Circuits, Terminals 13-20
Notification Circuits Terminals 21-22
Data Communication Circuits Terminals 25-26
• Do Not pull wires from different groups through the same conduit. If you must run them together, do so for
as short a distance as possible or use shielded cable. Connect the shield to earth ground at the panel only.
• High frequency noise, such as that produced by the inductive reactance of a speaker or bell, can also be
reduced by running the wire through ferrite shield beads or by wrapping it around a ferrite toroid.
• Route the wiring around the inside perimeter of the cabinet. It should not cross the circuit board where it
could induce noise into the sensitive microelectronics of pick up unwanted RF noise from the high speed
circuits. See Figure 3-1 for an example.

3.4.2 LED Descriptions
This section describes what each LED indicates. The 5104 has a total of seven LEDs, three are visible externally
and four are visible only if the cabinet door is open. See Section 8 for additional information on LED operation.
3.4.2.1 Externally Visible LEDs (L3, L4, & L5)
This section describes the three LEDs (one green and two yellow) that are visible externally through the window
on the 5104 cabinet door. Refer to Table 3-2 and Figure 3-2.
Table 3-2: Externally Visible LEDs
LED # Name Color Description
L3 Power Green
L4 Silenced Yellow
L5 Dialer Yellow
Normally ON unless the panel loses AC power or the panel is
being reset.
Normally OFF unless a trouble or supervisory condition has
been silenced.
Normally OFF unless there is a phone line or communication
problem. See Section 3.4.2.2 for additional information.
3.4.2.2 Phone Line Fault Indicator LEDs (L6 &L7)
The 5104 has a built-in dual-phone line monitoring circuit. This circuit detects any fault in the phone line by
monitoring the loop current and DC voltage. If the phone line drops to 1.8 VDC @ 5 mA or below for 40 to 90
seconds the on-board piezo and the corresponding LED will turn ON. The control panel will then report the fault
condition to the central station on the other phone line. For example, if phone line one looses phone line voltage,
the on-board piezo and the L6 will turn on, then the control panel will report the faulted line on phone line two.
See Figure 3-2 for LED Locations
Note: To comply with NFPA 72 the model 5104 is equipped with phone line seizure. This means that any time the
control panel dialer needs to communicate with the central station, it will not be possib le to use the telephones that are on the same line as the fire system. During communication to the central station the phone
lines will be seized for approximately one minute. However, under adverse telephone circuit conditions
phone line seizure could last as long as 15 minutes.
Table 3-3: Phone Line Fault Indicator LEDs

3.5 Calculating Current Draw and Standby Battery
This section should be used to help you determine the current draw and standby battery needs for your
installation.
3.5.1 Worksheet Requirements
The following steps must be taken when determining the 5104 current draw and standby battery requirements.
Fill in the Current Draw Worksheet (Table 3-6) in section 3.5.2.
For the 5104, the worst case current draw is listed in Table 3-6 for the panel and accessory devices.
Follow these steps to properly fill in the Current Draw Worksheet.
1. Fill in the number of devices used.
2. Compute the current draw requirements for alarm and standby and record this data into line A.
3. Add up the current draw for all the smoke detectors and record the totals in line B.
4. Total all the notification appliance device loads and enter that number into line C.
5. Make sure that the alarm current you calculated, including current for the panel itself, does not exceed 750
mA. This is the maximum current allowable.
6. Complete the remaining instructions in Table 3-6 to determine battery size requirements.
3.5.1.1 Maximum Battery Standby Load
Table 3-5 shows the maximum battery st andby load for the 5104 based on 24 and 60 hours of standby. the
