5522M and 5523M Duotronic 

Signal Installation Sheet

 

 

Description 

The 5522M and 5523M Duotronic Signals are high decibel signaling 

appliances intended for indoor use where distinctive audible signals 

are required in hazardous locations. The 5522M series are horns and 

the 5523M series are sirens. The units are rated at an average 110 dB.

 

The 5522M and 5523M series are UL and cUL listed for use in the 

hazardous locations shown in Table 2. 
The flange bolts of all series of the signals are sealed in accordance 

with UL requirements to prevent disassembly and tampering. 
This equipment is suitable for u

se in Class I, Division 1, Groups B, C, 

and 

D; Class I, Division 2, Groups A, B, C, and D

 hazardous locations 

for General Signaling Service

Installation 

Install and wire this device in accordance with applicable national and 

local codes, ordinances, and regulations, and in a manner acceptable 

to the local authority having jurisdiction. 

When the device is used in general signaling applications, you must 

install it in accordance with these instructions, and with the applicable 

requirements of NFPA 70 in the US or CSA C22.1 in Canada. 
When the device 

is used in Division 2 applications, you must install it in 

accordance with the NFPA 70 Article 501-

4b.

 

WARNINGS 

  Explosion hazard. Do not disconnect equipment unless power has 

been removed or the area is known to be nonhazardous. 

  Explosion hazard. Substitution of any components may impair 

suitability for Class I, Division 2.

 

  Explosion hazard. Do not disconnect equipment while the circuit is 

live or unless the area is known to be free of ignitable 

concentrations. 

 

To prevent fire, shock and component damage, no work, including 

circuit board removal, should be performed while the circuit is 

energized. 

To install the signal: 

1.  Choose the mounting location. The horn or siren can be mounted 

on any solid surface. Ensure that the mounting location provides 

adequate clearance to enable adjustment of the signal to the 

desired position after mounting. The signal position can be 

adjusted within an approximate 180-degree range vertically or 

horizontally depending on the mounting of bracket. 

2.  Mount the unit in the selected location using its mounting bracket 

and three bolts (not supplied). See Figure 1 for the unit size and 

the location of mounting holes. 

3.  Adjust the 

signal direction as desired, by loosening 

the two bolts 

shown in Figure 1

. Rotate the signal to the desired position,

 and 

then tighten the bolts. 

4

.  Wire the unit as shown in Figure 2 

a. 

Remove 

cover from the conduit outlet box (not supplied). Note 

that the outlet box must be suitable for use in the hazardous 

location. 

b.  Feed the two power supply wires through the 1/2 in. NPT 

conduit (not supplied) into the outlet box. 

c.  Feed the signal's two power connection wires either directly 

into the outlet 

box or, if desired, through a 1/2

 in. flexible type 

coupling (not supplied) and then into box. 

WARNING: 

Do not apply power to the unit until installation is 

completed and the housing cover and outlet box cover are 

secured. 
d.  Secure the outlet box to the signal's 1/2 - 

14 NPT

 sealed 

nipple either directly or by flexible coupling, and 

then secure 

the conduit to outlet box. 

e.  Connect the power supply wires using two wire nuts (not 

supplied). Polarity need not be observed when making 

connections for a DC voltage source. 

5. 

Replace 

the cover securely on the conduit outlet box. 

6.  Apply power to the signal and verify that it sounds correctly.
