GENERAL:
Wheelock's Series NS4 Horn Strobe Appliances are designed to provide independent operation for the horn appliance, when the
strobe circuit is powered. They are the ideal choice for retrofit applications as well as new installations. The NS4 Appliances are UL
Listed under Standard 1971 for Signaling Devices for the Hearing Impaired and UL Standard 464 for Audible Signal Appliances. The
1575W candela wall mounted strobes are listed at 15 candela under UL Standard 1971 and meet 75 candela intensity on axis with low
current draw. They are listed for indoor use only and equipped with a NS Mounting Plate (NSMP) that can be mounted to single-
gang, double-gang, 4" backbox, 100mm European backbox or SHBB surface backbox (See Mounting Options). These appliances are
Listed for wall mounting only. The NS4 Appliances use a Xenon flashtube with solid state circuitry enclosed in a rugged Lexan
lens to provide maximum visibility and reliability for effective visible signaling.
The horn portion of the NS4 Appliances can be field set to provide either Continuous Horn or Code 3 Horn. The sound output can be
field set for High (HI) or Low (LO) dBA.
The NS4 Horn Strobe can also be used with a Sync Module (SM) or Dual Sync Module (DSM) to provide synchronized strobe and
synchronized Code 3 signal.
These strobe models are designed for use with either filtered DC (VDC) or unfiltered Full-Wave-Rectified (VRMS) input voltage.
All inputs are polarized for compatibility with standard reverse polarity supervision of circuit wiring by a FACP.
