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.
