INSTALLATION INSTRUCTIONS

MULTI-CANDELA FOUR WIRE HORN STROBE APPLIANCES

(WALL MOUNT VERSION)

IMPORTANT

– All audible and visual signaling appliances must be

installed in accordance with all applicable national and local fire alarm

codes and any other required regulatory agencies.

Series HS-MC Multi-Candela Horn Strobe provides four selectable

candela settings (15, 30, 75, 110). The HS-MC allows for independent

operation of the strobe circuit and the horn circuit. It is the ideal choice

for retrofit applications as well as new installations. The HS-MC

appliance is UL Listed under Standard 1971 for Signaling Appliances

for the Hearing Impaired and UL Standard 464 for Audible Signal

Appliances. The HS-MC is also ULC Listed under Standard CAN/ULC-

S526-02 for Visual Signaling Appliances and Standard CAN/ULC-

S525-99 for Audible Signaling Appliances for Fire Alarm Systems. It is

listed for indoor use only

and can be mounted to double-gang, 4”

backbox, 100mm European backbox or MT-SUR-BOX surface

backbox (See wiring and mounting information). This appliance is

listed for wall mounting only

. The HS-MC appliance uses a xenon

flashtube with solid state circuitry enclosed in a polycarbonate lens to

provide maximum visibility and reliability for effective visible signaling.

Siemens Series HS appliances provide a selectable continuous or

Code 3 horn tone and non-synchronized strobe when connected

directly to a Fire Alarm Control Panel (FACP). They can also provide a

synchronized Code 3 (or March Time) horn tone and synchronized

strobe when connected to a notification appliance circuit running the

Siemens sync protocol. HS appliances can be field set for High (HI),

medium (MED) dBA or low (LO) dBA sound output. .

NOTE: The Code 3 temporal pattern (1/2 second on, 1/2 second off,

1/2 second on, 1/2 second off, 1/2 second on, 1-1/2 off and repeat) is

specified by ANSI and NFPA 72 for standard emergency evacuation

signaling. The Code 3 Horn should be used only for fire

evacuation signaling and not for any other purpose.

The HS-MC is designed for use with either filtered DC or unfiltered full-

wave-rectified (FWR) input voltage. All inputs are polarized for

compatibility with standard reverse polarity supervision of circuit wiring

by an FACP.

NOTE: All Canadian Installations should be in accordance with the

Canadian Standard for the Installation of Fire Alarm Systems –

CAN/ULC-S524-01 and Canadian Electrical Code, Part 1. Final

acceptance is subject to authorities having jurisdiction (AHJ).

NFPA 72/ANSI 117.1 conform to ADAAG Equivalent Facilitation

Guidelines in using fewer, higher intensity strobes within the same

protected area.

NOTE: Refer to P/N 315-096363 for the maximum number of

appliances on a single notification appliance circuit.
