Edwards Signaling 870 Series Indoor User Manual
Installation instructions for indoor adaptahorns
Description
The AdaptaHorns are UL listed vibrating horns. They are low
current, high decibel horns designed for heavy-duty use indoors.
The horns are intended for general signaling applications.
PLC Compatibility
The electrical input load requirements for PLC compatible sig-
naling devices are listed in Table 1. Signaling devices may be
directly connected to output cards that meet these input load re-
quirements.
24V DC electromechanical horns such as the 871-G1, 873-G1,
873DPO-G1 and 875-G1 can produce transient spikes and should
only be used on PLC output cards that have inherent transient
spike suppression. The Process Control Engineer should consult
the PLC manufacturer when connecting 24V DC electromechani-
cal devices to PLCs.
Installation
Flush Mounting (870 and 871 Series)
1.
Using approved wiring methods, connect black wire leads to
power source wires. Polarity is not important.
2.
Ground to wiring system.
3.
Insert horn connector into connector receptacle and secure
horn to backbox with (4) oval head screws (supplied).
Surface Mounting (872, 872DPO, 873, 873DPO, 874, and 875
Series)
1.
Loosen screw at bottom of horn and remove backplate.
2.
Mount plate using one of the following methods:
a.
Mount on any outlet box cover having single gang
opening using #6 screws (supplied).
b.
Mount on a 3 1/4" (83mm), 3 1/2" (89mm), 4" (102mm)
octagon or 4" (102mm) square box using #8 screws
supplied with backbox.
c.
Mount on the wall, for open wiring, using #8 wood screws
(supplied).
3.
Using approved wiring methods connect one wire to each
terminal in backplate. Ground to wiring system.
4.
Place the horn on the mounting plate so that the tab at the top
seats in slot on horn. Press horn firmly against plate and
tighten screw at bottom of unit. See Figure 1.
