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.

• HS-MC Appliances have in-out wiring terminals that accepts two #12 to #18 American Wire Gauge (AWG) wires at each
screw terminal. Strip leads 3/8” inches for connection to screw terminals.
• Break all in-out wire runs on supervised circuit supervision as shown in Figure 5. The polarity shown in the wiring
diagrams is for the operation of the appliances. The polarity is reversed by the FACP during supervision.
The following figures (A-D) show the maximum number of field wires (conductors) that can enter the backbox used with each mounting option. If these
limits are exceeded, there may be insufficient space in the backbox to accommodate the field wires and stresses from the wires could damage the
product. Check that the installed product will have sufficient clearance and wiring room prior to installing backboxes and conduit, especially if sheathed
multiconductor cable or 3/4" conduit fittings are used.

MOUNTING PROCEDURES:
1. This HS-MC model can be flush mounted to a 100mm
backbox (Figure A) or double-gang backbox (Figure B).
It can also be surface mounted to a indoor/outdoor
backbox (Figures C & D). Mounting hardware for each
mounting option is supplied.
2. Conduit entrances to the backbox should be selected to
provide sufficient wiring clearance for the installed
product. Do not pass additional wires (used for other
than the signaling appliance) through the backbox. Such
additional wires could result in insufficient wiring space
for the signaling appliance.
3. When terminating field wires, do not use more lead
length than required. Excess lead length could result in
insufficient wiring space for the appliance.
4. Use care and proper techniques to position the field wires
in the backbox so that they use minimum space and
produce minimum stress on the product. This is
especially important for stiff, heavy gauge wires and
wires with thick insulation or sheathing.
5. Connect field wires to the HS-MC terminal block (polarity
must be observed). Bend the field wires up 90°at the
connection to the terminal block.
6. Carefully push the field wires into the backbox by hand.
Press the HS-MC to the backbox, verifying that it is
seated and aligned correctly.
7. Fasten the HS-MC to the backbox using the supplied
screws.
The HS-MC 110cd setting is Listed for use in sleeping or non-sleeping areas when installed in accordance with appropriate NFPA Standards and the
AHJ.
WARNING: A SMALL POSSIBILITY EXISTS THAT THE USE OF MULTIPLE STROBES WITHIN A PERSON'S FIELD OF VIEW, UNDER
CERTAIN CIRCUMSTANCES, MIGHT INDUCE A PHOTO-SENSITIVE RESPONSE IN PERSONS WITH EPILEPSY. STROBE REFLECTIONS IN A
GLASS OR MIRRORED SURFACE MIGHT ALSO INDUCE SUCH A RESPONSE. TO MINIMIZE THIS POSSIBLE HAZARD, SIEMENS STRONGLY
RECOMMENDS THAT THE STROBES INSTALLED SHOULD NOT PRESENT A COMPOSITE FLASH RATE IN THE FIELD OF VIEW WHICH
EXCEEDS FIVE Hz AT THE OPERATING VOLTAGE OF THE STROBES. SIEMENS ALSO STRONGLY RECOMMENDS THAT THE INTENSITY AND
COMPOSITE FLASH RATE OF INSTALLED STROBES COMPLY WITH LEVELS ESTABLISHED BY APPLICABLE LAWS, STANDARDS,
REGULATIONS, CODES AND GUIDELINES.
