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.

Limitations of Fire Alarm Systems

Manufacturer recommends that smoke and/or heat detectors be located throughout a protected premise following the recommendations of the current edition of the National Fire Protection Association Standard 72 (NFPA 72 manufacturer’s recommendations, State and local codes, and the recommendations contained in Guide for the Proper Use of System Smoke Detectors, which is made available at no charge to all installing dealers. A study by the Federal Emergency Management Agency (an agency of the United States government) indicated that smoke detectors may not go off or give early warning in as many as 35% of all fires. While fire alarm systems are designed to provide warning against fire, they do not guarantee warning or protection against fire. A fire alarm system may not provide timely or adequate warning, or simply may not function, for a variety of reasons. For example:

• Particles of combustion or smoke from a developing fire may not reach the sensing chambers of smoke detectors because:

- Barriers such as closed or partially closed doors, walls, or chimneys may inhibit particle or smoke flow.

- Smoke particles may become cold, stratify, and not reach the ceiling or upper walls where detectors are

located.

- Smoke particles may be blown away from detectors by air outlets

- Smoke particles may be drawn into air returns before reaching the detector.

In general, smoke detectors on one level of a structure cannot be expected to sense fires developing on another level.

• The amount of smokepresent may be insufficient to alarm smoke detectors. Smoke detectors are designed to alarm at various levels of smoke density. If such density levels are not created by a developing fire at the location of detectors, the detectors will not go into alarm.

• Smoke detectors, even when working properly, have sensing limitations. Detectors that have photoelectronic sensing chambers tend to detect smoldering fires better than flaming fires, which have little visible smoke. Detectors that have ionizing-type sensing chambers tend to detect fast flaming fires better than smoldering

1-2

Introduction 151204

fires. Because fires develop in different ways and are often unpredictable in their growth, neither type of detector is necessarily best and a given type of detector may not provide adequate warning of a fire.

• Smoke detectors are subject to false alarms and nuisance alarms and may have been disconnected by users. For example, a smoke detector located in or near a kitchen may go into nuisance alarm during normal operation of kitchen appliances. In addition, dusty or steamy environments may cause a smoke detector to falsely alarm. If the location of a smoke detector causes an abundance of false alarms or nuisance alarms, do not disconnect the smoke detector; call a professional to analyze the situation and recommend a solution.

• Smoke detectors cannot be expected to provide adequate warning of fires caused by arson, children playing with matches (especially within bedrooms), smoking in bed, violent explosions (caused by escap ing gas, improper storage of flammable materials, etc.).

• Heat detectors do not sense particles of combustion and are designed to alarm only when heat on their sensors increases at a predetermined rate or reaches a predetermined level. Heat detectors are designed to protect property, not life.

• Warning devices (including horns, sirens, and bells) ma y not alert people or wake up sleepers who are located on the other side of closed or partially open doors. A warning device that activates on a different floor or level of a dwelling or structure is less likely to awaken or alert people. Even persons who are awake may not notice the warning if the alarm is muffled by noise from a stereo, radio, air conditioner or other appliance, or by passing traffic. Audible warning devices may not alert the hearing-impaired (strobes or other devices should be provided to warn these people). Any warning device may fail to alert people with a disability , deep sleepers, people who have recently used alcohol or drugs, or people on medication or sleeping pills.

- Please note that: i) Strobes can, under certain circumstances, cause seizures in people with conditions such as epilepsy. ii) Studies have shown that certain people, even when they hear a fire alarm signal, do not respond or com-

prehend the meaning of the signal. It is the property owner’s responsibility to conduct fire drills and other training exercises to make people aware of fire alarm signals and instruct on the proper reaction to alarm signals.

iii) In rare instances, the sounding of a warning device can cause temporary or permanent hearing loss.

• Telephone lines needed to transmit alarm signals from a premises to a central station may be out of service or temporarily out of service. For added protection against telephone line failure, backup radio transmission systems are recommended.

• System components, though designed to last many years, can fail at any time. As a precautionary measure, it is recommended that smoke detectors be checked, maintained, and replaced per manufacturer's recommendations.

• System components will not work without electrical power. If system batteries are not serviced or replaced regularly, they may not provide battery backup when AC power fails.

• Environments with high air velocity or that are dusty or dirty require more frequent maintenance.

In general, fire alarm systems and devices will not work without power and will not function properly unless they are maintained and tested regularly.

While installing a fire alarm system may make the owner eligible for a lower insurance rate, an alarm system is not a substitute for insurance. Property owners should continu e to act prud ently in protecting the premises and the people in their premises and should properly insure life and property and buy sufficient amounts of liability insurance to meet their needs.

3.2 Environmental Specifications

It is important to protect the SK-5208 control panel from water. To prevent water damage, the following conditions should be AVOIDED when mounting the units:

• Do not mount directly on exterior walls, especially masonry walls (condensation).

• Do not mount directly on exterior walls below grade (condensation).

• Protect from plumbing leaks.

• Protect from splash caused by sprinkler system inspection ports.

• Do not mount in areas with humidity-generating equipment (such as dryers, production machinery).

When selecting a location to mount the SK-5208 control panel, the unit should be mounted where it will NOT be exposed to temperatures outside the range of 0°C-49°C (32°F-120°F) or humidity equal to or greater than 93% at 30°C (89°F) noncondensing.

See also the mounting recommendations in Section 3.5 for additional environmental specificati ons.

3.3 Wiring Specifications

To avoid induced noise (transfer of electric al energy from one wire to another), keep input wiring isolated from high current output and power wiring. Induced noise can interfere with telephone communication or even cause

false alarms. Avoid pulling one multiconductor cable for the entire panel. Instead, separate the wiring as follows:

Input/Output Type Wiring

1/4" spacing must be maintained between each of these circuit types; as well as between power limited and non-power limited circuits.

High Voltage: AC power Low Voltage: Annunciator, zone circuit wiring, and notification devices Audio: Speaker Telco Separated

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.

For the same reasons, 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 high speed circuits.

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. Figure 3-1 provides an example.

Control Panel Installation 151204

3.5 Mounting the SK-5208

Read the environmental specifications in section 3.2 on page 1 before mounting the SK-5208 panel. The SK-5208 cabinet dimensions are:

16" W x 26.4" H x 4" D (40.64 cm W x 67.06 cm H x 10.16 cm D).

The SK-5208 panel should be located within a secured area, where it is accessible to main drop wiring runs and where it can be easily tested and serviced. End-users responsible for maintaining the panel should be able to hear alarms and troubles. When selecting a location, keep in mind that the panel itself is the main source of alarm and trouble annunciation.

When mounting on interior walls, use appropriate screw anchors in plaster. When mounting on concrete, especially when moisture can accumulate, the enclosure shall be placed or equipped so as to prevent moisture or water from entering and accumulating within the cabinet, and shall be mounted so there is a least 1/4” space between the enclosure and the concrete wall surface. A piece of plywood, standoffs, or other equivalent material can be used to space the cabinet from the concrete surface and then attach the SK-5208 to that spacing surface. Also mount any other desired components to the 1/4” spacing surface.

DO NOT flush-mount the SK-5208 cabinet in a wall designated as a fire break.

3.5.1 Preventing Water Damage

Water damage to the fire system can be caused by moisture entering the cabinet through the conduits. Conduits that are installed to enter the top of the cabinet are most likely to cause water problems. Installers should take reasonable precautions to prevent water from entering the cabinet. Water damage is not covered under warranty.

3.6 Current Draw Calculations

3.6.1 Worksheet Requirements

The following steps must be taken when determining SK-5208 current draw and standby battery requirements.

Filling in the Current Draw Worksheet, Table 3-2 (Section 3.6.2)

1. For the SK-5208, the worst case current draw is listed for the panel and panel accessories. Fill in the number of devices that will be used in the system and compute the current draw requirements for alarm and standby . Record this information in Table 3-2 at Line A.

2. Add up the current draw for all smoke detectors and record in the table at Line B.

3. Add up all notification appliance loads and record in the table at Line C.

4. For notification appliances and auxiliary devices not mentioned in the manual, refer to the device manual for the current ratings.

5. Make sure that the total alarm current you calculated, including current for the panel itself, does not exceed

6.0 A. This is the maximum alarm current for the SK-5208 control panel. If the current is above 6.0 A you will need to use a notification power expander(s) such as the 5495 to dis-

tribute the power loads so that the SK-5208 or the power expanders do not exceed their power rating. Refer to the current draw worksheets provided with the 5495 manuals so you do not exceed their power requirements.

6. Complete the remaining instructions in Table 3-2 for determining battery size requirements.

3.10 Telephone Line Connection

The SK-5208 connects to two separate telephone lines to report data to the central station. An RJ31X jack should be installed by the telephone company for each line. Figure 3-4 shows how to wire the telephone line interconnect cords (not provided) to the SK-5208.

Note: To reduce the possibility of false alarms and transient damage, DO NOT bundle telephone wires together

with initiation or notification device wires.

Figure 3-4 Telephone Line Connection

The letter designator on the phone input indicates whether it is the Telco or House side of the phone circuit. For example terminals 60 and 61 are labeled T1, T = Telco side of the phone circuit and terminals 58 and 59 are labeled P1, P = Premise (House) side of the phone circuit.

The SK-5208 has built-in dual phone line monitors. These circuits will detect any fault in the phone lines by monitoring the DC voltage present on the lines. If phone line voltage drops below 3 VDC and is not corrected within approximately 60 seconds, an audible trouble signal will sound and the panel will report a line fault trouble over the remaining phone line.

A situation could occur where both phone lines appear to be good, but the dialer cannot get through to the central station on the first line. In this case, the SK-5208 will switch phone lines and attempt the call again using the second line. Make sure the phone lines are programmed properly (see Section 4).

Note: To comply with industry standards, this product is equipped with line seizure. Any time the system’s dialer

needs to communicate with the central station, it will not be possible to use any telephones that are on the same line(s) as the system. Normally, this condition will last approximately one minute, but under adverse telephone circuit conditions, could last for as long as 15 minutes.

3.11 Detector Installation

3.11.1 Class A (Style D) Zones

Zones 1 and 2 may be selected through programming as Class A (Style D) zones (see Section 4.2.2 for zone style programming). See Section 3.11.2 for Class B (Style B) configuration.

Each class A zone is a four-wire circuit that allows an alarm to be detected even after a single open or ground fault occurs. When a single open or ground fault occurs, the audible trouble signal will sound and the SK-5208 will report the trouble to the central station or remote station (if programmed to report troubles). If reporting to a remote station troubles may be transmitted to a secondary location.

Figure 3-5 shows how to wire a Class A (Style D) circuit. No end-of-line (EOL) resistors are needed for these

zones. These zones must be wired using normally open contacts.

Figure 3-5 Class A (Style D) Supervised Fire Circuit

Maximum voltage: 17.5 to 28 VDC Full Wave Rectified Circuit Current: 95 mA Maximum circuit Resistance: 50 ohms

3.11.2 Class B (Style B) Zones

Zones 3 through 10 are Class B (Style B) only fire zones. Zones 1 & 2 may also be programmed as Class A (Style D) or Class B (Style B), see Section 4.2.2 for zone 1 & 2 zone programming.

Each Class B zone consists of a two-wire circuit that will detect the occurrence of an open in the circuit, but may not be able to detect an alarm after such an occurrence. The detection of an open will cause the audible trouble signal to sound and the SK-5208 will report the trouble to the central or remote station (if programmed to do so).

Figure 3-6 shows how to wire a Class B (Style B) circuit. One side of each Class B circuit connects to a zone input terminal and the other side of each circuit connects to Smoke power. For each circuit, use a 4.7K-ohm EOL resistor wired in parallel with the normally open contact farthest from the panel.

3.11.3 Four-Wire Smoke Detector Connection

Figure 3-7 illustrates how UL listed four-wire smoke detectors must be connected to Class B (Style B) zones. When wiring a four-wire smoke detector to the Class B (Style B) zones, you must use a Power Supervision Unit,

such as Silent Knight’s 160150.

Note: Mount the PAM-2 and the end-of-line resistor at the last device on the circuit.

The section describes how to install the SK-5235 Remote Annunciato r, SK-5217 Zone Expander, the 5824 Serial/Parallel Printer Module, and the SK-5280 Status Display Module. All circuits are 24 VDC regulated. All S-Bus devices are Style 1 Class B as per NFPA 72.

3.14.1 Setting ID Codes

Before installing the SK-5235, SK-5217, 5824 or SK-5280, you must first set their identification codes. Each device must be given its own identification code. For example: each SK-5235 needs a unique ID code, but a SK5235 can have the same ID code as a SK-5217. Each type of device has it’s own device type programmed into it enabling the control panel to distinguish between the different devices.

On the back of each device is a small 4-position dip switch used to set the ID code. Use the chart below to
