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.
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).
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. .
