NOTICE: This manual shall be left with the owner/user of this
equipment.
Suitable	for	outdoor	use	in	wet	environments	with	outdoor	back	
box	supplied	with	the	product.
General Description
The	 National	 Fire	 Protection	 Association	 (NFPA)	 has	 published	
standards	and	recommended	practices	for	the	speakers	described	
in	 this	 manual.	 As	 a	 result,	 the	 installer	 must	 be	 familiar	 with	
these	requirements	as	well	as	all	local	codes	and	special	require-
ments	of	the	authority	having	jurisdiction.
SP201K	 series	 speaker	 can	 be	 operated	 with	 distribution	 ampli-
fiers	having	an	output	voltage	of	either	25	volts	or	70.7	volts.
The	speaker	operates	at	any	one	of	four	input	power	levels.	The	
output	sound	level	is	selected	at	the	time	of	installation,	but	can	
be	changed,	if	necessary.
The	speaker	is	also	equipped	with	a	capacitive	input	to	allow	for	
DC	supervision.
Installation
All	 wiring	 must	 be	 installed	 in	 compliance	 with	 the	 National	
Electrical	 Code	 (NEC)	 and	 applicable	 local	 codes	 as	 well	 as	
special	 requirements	 of	 the	 authority	 having	 jurisdiction,	 using	
the	 proper	 wire	 size.	 This	 also	 includes	 all	 applicable	 NFPA	
Standards,	ANSI/UL	1480,	and	NEC	760.
Electrical
1.	Connect	the	speaker	as	shown	in	Figure	1.	
NOTE:		Do	not	loop	electrical	wiring	under	terminal	screws.	Wires	
connecting	the	device	to	the	control	panel	must	be	broken	
at	 the	 device	 terminal	 connection	 in	 order	 to	 maintain	
electrical	supervision.
