SKE-SRM Remote Microphone
Module Installation Instructions

The SKE-SRM is a supervised remote
microphone assembly that can be added to the
SKE-Series voice evacuation system.

Compatibility

The SKE-SRM is compatible with the SKE­Series voice evacuation system.

Mounting

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 SKE­SRM 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.

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. Place microphone in a safe
location while completing cabinet
installation.

4. Remove the cover plate by un-screwing the
four cover plate screws. Set the screws aside
for later use.

5. Remove the remote microphone chassis
assembly by un-screwing the two chassis
assembly screws. See Figure 1.
