CU ALARM
___________________________________________________________________________________
The CU Alarm is an audible alarm
that sounds in the event the
steam room maximum set
temperature is exceeded or if the
CU-SteamStop button has been
pressed.
The CU Alarm may be mounted
outside the steam room in a
location that will alert an
attendant and/or user to an
over-temperature condition.
Review local codes for mounting location
as required

Instructions Carefully Before Using this
Product. The 115VAC CU Alarm must be field
set to the desired dBa sound output level and
alarm tone before installation. This is done
by adjusting a four position switch in accordance with these instructions. Incorrect settings will result in improper performance.

MAKE SURE THAT ALL FUSES USED ON SIGNALING
CIRCUITS ARE RATED TO HANDLE THE MAXIMUM INRUSH OR PEAK
CURRENT FROM ALL APPLIANCES ON THOSE CIRCUITS. FAILURE TO DO
THIS MAY RESULT IN LOSS OF POWER TO THE SIGNALING CIRCUIT AND
THE FAILURE OF ALL APPLIANCES ON THAT CIRCUIT TO OPERATE.
The CU Alarm produce a brief inrush current that lasts for just 50
microseconds at a peak value of 5.0 Amps.

!
IF 115VAC CU ALARMS ARE OPERATED WITHIN 15
INCHES OF A PERSON, THEY CAN PRODUCE A SOUND PRESSURE LEVEL
THAT EXCEEDS THE MAXIMUM 120 dBA PERMITTED BY ADA AND OSHA
RULES. EXPOSURE TO SUCH SOUND LEVELS CAN RESULT IN HEARING
DAMAGE.
SETTINGS:
The Switch (SW1) of the CU Alarm, shown in Figure 1, is used to set
the desired dBA sound output level and alarm tone. The factory settings are shown below. Read these instructions carefully before changing any of these factory settings.

accordance with National and local electrical codes.
Review local codes for mounting location as required
WARNING
!
DO NOT mount the CU ALARM
.
inside the steam room.
CAUTION
!
conduit fittings are used, check that installed CU Alarm has sufficient clearance and wiring room prior to installing electrical
boxes and conduit.
1.115 VAC CU ALARMs can be surface mounted to a
standard 4 inch square by 2-
box (Figure A)
2. Select the largest electrical box possible (shown in Mounting
Options) to provide the maximum wiring clearance for easy
installation.
3. Conduit entrance to electrical boxes should be selected to
insure sufficient wiring clearance for the CU Alarm. When
extension rings are required, conduit should enter through
electrical box, not extension ring.
4. Use care and proper techniques to position the field wires in
the electrical box so that they use minimum space and produce minimum stress on the product. This is especially important for stiff, heavy gauge wires with thick insulation or
sheathing.
5. Do not pass additional wires (used for other than signaling
appliances) through the electrical box. Such additional wires
could result in insufficient wiring space for the signaling
appliance. The CU Alarm is designed to produce an audible
alarm in the event the steam room maximum set temperature
is exceeded.
6. Place the CU-ALARM identification label on or adjacent
to the alarm.
IMPORTANT NOTE:
incorporate the temporal pattern specified by NSI/NFPA/
ISO for standard emergency evacuation signaling.
They should be used only for fire evacuation signaling
and not for any other purpose.
