button (for CMD 1 message) or S2 button (for CMD 2 message). When the S1 or S2 button is
pressed for 1 second, the audio message and notification output will begin sounding,
simulating an actual CMD input alarm. The message and notification will continue to sound
(as programmed) for ten minutes, or you can manually silence them by pressing the same
CMD button for 1 second. See Section 4.2 for S1 and S2 functions in recording mode.

151267 3-7

SKE-Series Voice Evacuation System Installation/Operation Manual

3.3.10 AC Delay Switch

The SKE-450 has two built-in trouble relays – General Trouble and AC Trouble.

The General trouble relay will energize when any trouble condition is detected. If the only
trouble condition is an AC failure, the relay output can be programmed to delay the indication
by 2 hours by setting the DIP AC Delay Switch 1 to ON. If the AC Delay Switch is in the OFF
position the trouble relay will energize immediately when AC power fails. See Figure 3-1 for
AC Delay Switch location. The AC Delay Switch may be used only when the SKE-450 is
connected to an FACP that uses central station or off premise signaling.

The AC trouble relay will energize when an AC trouble is detected regardless of the settings
of the AC delay switch.

3.4 Mounting the Control Panel

Read the environmental specifications in Section 3.1 before mounting the control panel
cabinet. This will ensure that you select a suitable mounting location.

The panel should be accessible to main drop wiring runs. It should be mounted as close to the
center of the building as possible and located within a secured area, but should be accessible
for testing and service.

Mount the control panel cabinet so it is firmly secured to the wall surface. When mounting on
concrete, especially when moisture is expected, attach a piece of 3/4-inch plywood to the
concrete surface and then attach the cabinet to the plywood. Also mount any other modules to
the plywood.

The cabinet can be surface or flush-mounted. If you will be flush-mounting the cabinet, the
hole for the enclosure should be 14.5" W x 24.75" H x 3-7/16" D (36.8cm W x 62.9cm H x

8.73cm D). Do not flush-mount in a wall designated as a fire break.

3.4.1 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.

3.4.2 Wiring Specifications

The maximum line resistance of the wire run from FACP to voice evacuation control system is
50W. All wiring and devices installed in the system must meet the standards described in
National Electrical Code (NFPA 70), NFPA Standard 72, and Life Safety Code (NFPA 101).

To avoid induced noise (transfer of electrical energy from one wire to another), keep input
wiring isolated from high-current output and power wiring. Avoid pulling one multiconductor
cable for the entire panel. Instead, separate the wiring as follows:

Table 3-6

1/4" spacing must be maintained Input/Output Type Wiring

between each of these circuit types; Non Power-Limited: AC power, Standby batteries

as well as between power limited Power-Limited: Notification devices, SKE-SRM, and Relays

and non power-limited circuits. Audio: Speaker

DO NOT pull wires from different groups through the same conduit.

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 beads or by wrapping it around a
ferrite toroid core. Figure 3-5 provides an example.

3.6 Speaker Wiring

Each SKE-450 supplies one NAC (Notification Appliance Circuit) for speaker connection.
The speaker circuit can be supervised and wired Class B (Style Y) or Class A (Style Z). The
speaker circuit is capable of 50 watts of power at 25 Vrms or 70.7 Vrms (using the SKE-V70
Module, see Section 8 for SKE-V70 installing instructions).

Note: If the SKE-V70 Module is installed, all speaker wiring must be separated by a minimum of 1/4” from the

low voltage wiring, and must exit the cabinet through its own opening.

7.3 Installation Instructions

This section contains the information needed to properly install the SKE-SRM.

7.3.1 Mounting the SKE-SRM Cabinet.

It is important to protect the SKE-SRM 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 inspection ports

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

When selecting a location to mount the SKE-SRM cabinet, 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%-85% at 30°C (86°F) noncondensing.

Follow these steps to mount the remote microphone cabinet:

1. Remove the SKE-SRM from it’s packing container.

2. Unlock the cabinet and remove the cabinet door.

3. Unplug microphone from microphone connector. See Figure 7-1.

Place microphone in a safe location while completing cabinet installation.

4. Remove the cover plate by un-screwing the four cover plate screws (see Figure 7-1). Set
the screws aside for later use.

5. Remove the remote microphone chassis assembly by un-screwing the two chassis assem­bly screws. See Figure 7-2.

Important! The electronic components on the control panel are sensitive to electrostatic discharge

(static electricity). Wear a grounding strap when handling the control board.
