Operation
Installation
The Flex-Tone Panel Hazardous Location Use Speaker/Amplifiers are intended for industrial applications where hazardous locations require highly audible signals and microcomputer reliability.
The ETH645 & ETH845 Series Speaker/Amplifiers are heavyduty signaling appliances intended primarily for industrial
signaling applications. Each unit operates from local power
and sounds either a tone determined by the programming
at the Central Tone Generator or from another audio source.
Speaker direction and output level are easily adjustable.
The ETH645 & ETH845 Speaker/Amplifiers are UL listed for
use in Class I, Groups B, C, and D atmospheres.
Installation is to be completed in accordance with the latest
edition of either the National Electrical Code or the Canadian Electrical Code, as applicable, and in accordance with
the authorities having jurisdiction.
1. Mount Flex-Tone Speaker/Amplifier to any solid surface
using its mounting bracket and (3) bolts (not supplied)
(Figure 2).
W ARNING
Keep mating surfaces of housing clean and
undamaged to maintain the integrity of the
Hazardous Location construction.
2. Open Speaker/Amplifier by removing the (8) nuts and
bolts and lifting off housing cover.

Do not apply power to the unit until installation is
completed and housing cover and outlet box cover
are secured.
To prevent fire and shock, do not connect power to
TS1 terminals.
3. Wire Speaker/Amplifier as follows
a. Speaker/Amplifier Wiring (Figure 3). Check the
label for the correct operating voltage. Bring the
power and tone output circuit wires to the Speaker/
Amplifier through a 1/2" (13 mm) conduit attached
to a conduit outlet box and nipple. The conduit

outlet box, conduit and nipple must be suitable for
the hazardous location application with 1/2" (13
mm)-14 NPT threading at the conduit openings. The
conduit outlet box is not supplied.
6. If loosened, secure the cover of the Speaker/Amplifier
ensuring mating surfaces are clean and undamaged.
Align the straight edge of the cover with the straight
edge of the housing. Torque the housing nuts on the
Speaker/Amplifiers evenly and in opposing pairs to 140
to 150 in-lb.
Remove the cover from the conduit outlet box. Feed
the Speaker/Amplifier's four numbered wires and
the green ground wire through a 1/2" (13 mm)-14
NPT nipple (not supplied) and then into the conduit
outlet box. Secure the outlet box to the Speaker/
Amplifier.
7. Verify operability of each unit.
Connect green ground wire to earth ground
(Figure 3).
Maintenance and Test
Connect the external wires to the Speaker/Amplifier
wires using five wire nuts (not supplied) (Figure 3).
Polarity must be observed when connecting both
the tone signal and input power wires.
Examine the speaker/amplifiers semi-annually for external
accumulation of dirt. Clean if necessaary.
WARNING
4. The sound level is factory set to maximum. Adjust
volume, if desired, by turning potentiometer R72
(Figure 2).
Ensure that power is off prior to opening the unit.
Both the speaker/amplifier and central tone generator units
should be tested annually to ensure continuous service.
5. Adjust Speaker/Amplifier direction by loosening two (2)
nuts securing the mounting bracket to the Speaker/
