Edwards Signaling 871P - Manual

870P and 871P Panel Mount AdaptaHorn
Installation Sheet
Description
The AdaptaHorns are UL listed vibrating horns. They are
panel mounted, 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
signaling devices are listed in Table 1. Signaling devices may
be directly connected to output cards that meet these input
load requirements.
24 VDC electromechanical horns such as the 871P-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 24 VDC electromechanical
devices to PLCs.
Installation
1. Panel Mounting (Indoor or NEMA 4X, 12, 12K/Outdoor)
Locate device to assure adequate spacing to other
components. For live components at 250V or less, the
recommended spacing is 1 1/4" (32mm) from device to
live components mounted on the same surface and 1/2"
(13mm) minimum between device and dead metal
components other than mounting surface, unless
otherwise dictated by local authorities, responsible design
practices, or higher voltages.
Place the mounting template (Figure 1 on page 2), or the
supplied trim gasket (do not remove protective backing),
against the mounting surface. Mark and drill the mounting
holes, and device clearance/wire entrance hole. For
NEMA Type 4X, 12, 12K and outdoor applications,
mounting must be to a smooth, flat surface of a NEMA
Type 4X, 12, 12K enclosure or outdoor rated panel and all
four mounting holes must be drilled.
2. Box Mounting (Indoor Only)
Select and install a standard 4" (102mm) square box.
Note: See device label for voltage specifications.
3. Route power source wiring. Connect incoming wires to
the supplied (female) connector assembly using wire nuts
(not supplied).
870P AC models have (2) black and (1) green ground
wire. Polarity is not important.
871P DC models have a positive red lead, a negative
black lead and a green ground lead. Polarity is important.
4. This device is supplied with an adhesive backed trim
gasket. Remove the paper backing and apply adhesive
side to back of unit. Use gasket when mounting the unit to
an outdoor panel or for NEMA Type 4X or 12, 12K
applications, or whenever extra sealing is desired.
5. Plug the male connector (on the device), into the female
connector.
6. NEMA 4X, 12, 12K/Outdoor Mounting: Position the
device onto the surface and secure using (4) #8-32
countersunk head thru-bolts, lockwashers and nuts
(supplied).
Indoor or Box Mounting: Position the device on the
surface and secure using (2) #8-32 countersunk head
thru-bolts, and nuts (when mounting to a panel). The (2)
unused holes can be plugged with (2) #10-32 thread
forming countersunk head bolts or can be used to further
secure the device using (2) additional #8-32 countersunk
head thru-bolts, and nuts (when mounting to a panel).
7. These devices have a volume adjustment set screw
(located on the grille front) which is factory set at the
maximum level. To reduce volume level, turn set screw
clockwise using the supplied 1/16" allen wrench.
