Installation Procedure

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. Remove DC power 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. FACP (Fire Alarm Control Panel) operation and reliability depend upon proper installation.

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.

Overview

Limitations of Fire Alarm Systems

Requirements and recommendations for proper use of fire alarm systems including smoke detectors and other fire alarm devices:

•To keep your fire alarm system in excellent working order, ongoing maintenance is required per the manufacturer’s recommendations and UL and NFPA standards.

At a minimum the requirements of Chapter 14 of NFPA 72, 2010 Edition shall be followed. A maintenance agreement should be arranged through the local manufacturer’s representative. Maintenance should be performed annually by authorized personnel only.

The most common cause of an alarm system not functioning when a fire occurs is inadequate maintenance. As such, the alarm system should be tested weekly to make sure all sensors and transmitters are working properly.

Section 2

Before you Begin Installing

This section of the manual is intended to help you plan your tasks to complete the installation. Please read this section thoroughly, especially if you are installing a SKFFT for the first time.

2.1Environmental Specifications

It is important to protect the SK-FFT control panel from water. To prevent water damage, the following conditions should be AVOIDED when installing 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-FFT, 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 outside the range of 10% - 93% at 30°C (86°F) noncondensing.

2.2Preventing Water Damage

Water damage to the fire fighters phone 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.

2.2.1Removing the SK-FFT Assembly from the Housing

If it should ever be necessary to remove the control panel assembly from the cabinet for repair, do so by removing the screws that hold the control panel in to the cabinet. Do not attempt to disassemble the circuit boards.

2.5Wiring Specifications

Induced noise (transfer of electrical energy from one wire to another) can interfere with telephone communication or 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:

SLC loops	Audio circuits
Relay circuit

•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.

Twisted, shielded wire on the Audio Circuits is recommended for maximum protection against EMI and AFI emissions and susceptibility. Connect the shield to earth ground at the panel. You must route high and low voltages separately.

•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 or pick up unwanted RF noise from the high speed circuits. See Figure 2-4 for an example.

•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.

2.6Wire Routing

You must follow power-limited wiring techniques, which include maintaining onequarter inch spacing between power-limited and non-power limited circuits and separating high and low voltage circuits.

Power Limited	Non-Power limited
	Relay Circuit

Non power limited wiring must be run separately from power limited wiring

3.1Mounting the Cabinet

Read the environmental specifications in Section 2.1 before mounting the SK-FFT cabinet. This will ensure that you select a suitable location.

The cabinet can be surface or flush mounted. Do NOT flush-mount in a wall designed as a fire break.

3.1.1Surface Mounting

The Cabinet can be mounted on the wall surface by using the mounting holes in the back of the cabinet (see Figure 3-1).

1.Insert two screws level with each other, 14" apart for the top cabinet key shaped holes. See Figure 3-1.

2.Hang the cabinet onto the two screws. Tighten the screws down.

3.Insert two screws into the two bottom mounting holes and tighten them snug to the cabinet.

3.1.2Flush Mounting

This section describes how to flush mount the cabinet into a wall. To recess mount the cabinet you will need to have the optional trim ring P/N VIP-TR (ordered separately).

Follow these steps to recess mount the cabinet:

1.Remove the cabinet door and the dead front panel.

2.Cut a recess hole 20-1/4” W x 26-3/4” H (51.44 cm W x 67.95 cm H). There should be 1.5" to 1.75" of cabinet extruding from the wall, this should be measured from either the top edge or bottom edge to the exterior side of the sheet rock. (See

Figure 3-2.)

Important!

Do not insert the cabinet deeper than recommend above. If the cabinet is mounted to deep you will not be able to re-attach the door assembly.

3. Mount the cabinet to wall studs by inserting a screw through the cabinets side mounting holes into the wall stud.
