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 inserting cards, 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 are 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. These 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 limitations. 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.

3.3Wiring Specifications

Induced noise (transfer of electrical energy from one wire to another) can interfere with telephone communication or even cause false alarms. To 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.

3.4.2LED 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	Normally ON unless the panel loses AC power or the panel is
				being reset.
	L4	Silenced	Yellow	Normally OFF unless a trouble or supervisory condition has
				been silenced.
	L5	Dialer	Yellow	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 possible 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

LED #	Name	Color	Description
			Visible only when the 5104 cabinet is open. If ON indicates
			that phone line 1 is faulted. A faulted condition is indicated if
L6	Phone Line 1 Fault	Red	the phone line voltage drops below 1.8 VDC and the loop
			current is less than 5 mA. Flashing indicates a communication
			error has occurred.

3.4.2.3 Overcurrent LED Indicators (L1 & L2)

The 5104 has two red LEDs which indicate if excessive current is being drawn by a device connected to either the Accessory Power or Smoke Power circuits. Table 3-4 lists the two overcurrent LEDs and gives a description of them. See Figure 3-2 for LED locations.

Table 3-4: Overcurrent LED Description

	LED #	Name	Color	Description
		Accessory Power		If a device connected to the accessory power circuit draws
	L1		Red	more than 750 mA the overcurrent poly fuse will open and L1
		Fault
				will turn on.
				If a device connected to the smoke power circuit draws more
	L2	Smoke Power Fault	Red	than 750 mA the overcurrent poly fuse will open and L2 will
				turn on.

If either L1 or L2 turn on disconnect power immediately. Refer to Section 8 for troubleshooting information.

3.4.3Reset / Silence Switch

The Reset/Silence switch has three functions:

•Silences audible trouble, or supervisory signals. A trouble or supervisory piezo annunciation will be silenced immediately when you press the switch.

Note: If the switch is depressed for 15 seconds or longer an audible trouble signal will occur

•Resets smoke detector power. This function removes power from terminals 6, 9 and 11.

Note: To reset smoke detector power, depress the reset /trouble switch for a minimum of 1 second.

•Reset accessory powered devices. This function removes power from terminal 24.

Note: To reset accessory powered devices depress the reset/silence switch for a minimum of 1 second

The Reset/Silence switch is accessible inside the panel (DO NOT install the switch extender provided with the system) for UL certified installations.

3.4.4Cable Connectors (P1, P2, and P3)

There are two connectors on the 5104 (see Figure 3-2 for P1 and P2 locations). The function of these connectors is as follows:

Connector	Function
P1	Connects the wires from the secondary winding of the AC transformer
	to the control panel. (See Section 8 Troubleshooting for additional
	information.
P2	Used as a quick-connect for the 5230 Remote Annunciator to do
	programming or troubleshooting.
P3	Standby battery connector.

3.4.5On-board Piezo Sounder

The on-board piezo sounder gives an audible output for trouble, and supervisory conditions. Troubles and supervisories can be silenced with the Reset/Silence switch immediately.

3.5Calculating Current Draw and Standby Battery

This section should be used to help you determine the current draw and standby battery needs for your installation.

3.5.1Worksheet 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 standby load for the 5104 based on 24 and 60 hours of standby. the standby load calculations of line D in Table 3-6 must be less than the number shown in Table 3-5 for the battery size used and standby hours required.
