GENERAL:

The Supervised Self-Amplified Strobe Speakers are UL Listed under Standard 1480, Speakers for Fire Protective Signaling Systems,

UL Standard 1711, Amplifiers for Fire Protective Signaling Systems, and UL Standard 1971, (Emergency Devices for the Hearing

Impaired) for Indoor Fire Protection Service. They are Listed for indoor use only

. The LSM and SLM strobes are listed at 15

candela under UL Standard 1971 and meet 75 candela intensity on axis with low current draw. The SA Self-Amplified Strobe

Speakers are a combination of a speaker, a 1 watt amplifier and a strobe. The output level is switch selectable for 3 different sound

levels. The SA strobe speaker units are designed to be used with Wheelock’s SAFEPATH Voice Alarm Panel. SA models using

LS/MS/IS/SL are listed for ceiling or wall mount; LSM/SLM models are listed for wall mount only. All SA Strobe Speakers are

designed to fit into a 4” square deep backbox with an extension ring (See Mounting Options).

The SA Strobe Speakers, using the SL and SLM Series Sync Strobes, are designed to work with Wheelock’s Sync Modules; Sync

Control Module (SCM), Sync Module (SM) and the Dual Sync Module (DSM) to provide synchronized flashes when the sync strobes

are activated. Flash rate for the sync strobes with the Sync Modules is a steady one flash per second across a voltage range of 20-

30VDC.

All Supervised Self-Amplified Strobe Speakers use a Xenon flashtube with solid state circuitry enclosed in a rugged Lexan lens to

provide maximum visibility and reliability. All inputs are polarized for compatibility with standard reverse polarity supervision of

circuit wiring by a Fire Alarm Control Panel (FACP).

All models are UL Listed for indoor use with a temperature range of +32

F to +120

F (0

C to +49

C) and maximum humidity of

85% RH.
