WARNING

Keep mating surfaces of housing clean and
undamaged to maintain the integrity of the
Hazardous Location construction.

Edwards Hazardous Location Use Adaptatone signals, catalog
numbers 5533MD-AW, are tone-selectable, diode-polarized, au­dible signaling appliances primarily intended for use in fire alarm
systems and other applications requiring electrical supervision of
signaling circuit field wiring. The signals can be field programmed
to sound any of 56 tones. Descriptions of the tones are provided
in Table 1. Directions for tone programming and information re­garding suitability of the tones for fire alarm use are provided on
the inside of the signal's housing cover.

The 5533MD-AW models are UL and ULC listed for safe use in
Class I Groups B, C and D atmospheres.

(Figure 2) for the desired tone(s). Refer to tone program chart
on inside cover and Table 1.

Select one tone and set SW1 (Figure 2).

4. Check Adaptatone label for proper operation voltage. Install
power source and initiating circuit wires through a 1/2" (13
mm) conduit attached to an outlet box and nipple. The outlet
box, conduit and nipple must be suitable for the Hazardous
Location application with 1/2" (13 mm)-14 NPT threading at
conduit openings. Outlet box, conduit and nipple are not
supplied.

Remove cover from outlet box. Feed five numbered wires
through a 1/2" (13 mm)-14 NPT nipple (not supplied) into the
outlet box. Secure outlet box to Adaptatone.

WARNING

Do not apply power to the unit until installation is
completed and housing cover and outlet box cover
are secured.

6. The sound level is factory set to maximum. Adjust volume
level, if desired, by turning potentiometer R72 (Figure 2).

7. Adjust speaker direction by loosening (2) nuts and pivoting
speaker to desired position (Figure 3). Tighten (2) nuts.

8. Ensure mating surfaces are clean and undamaged. Secure
housing cover aligning the straight edge of the cover with the
straight edge of the housing. Torque nuts evenly in opposing
pairs to 140 to 150 in-lb. Apply power.
