INSTALLATION INSTRUCTIONS
MULTI-CANDELA AUDIBLE STROBE APPLIANCE
(CEILING 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 Audible Strobe Multi-Candela (AS-MC-C) Appliance is the
industry’s first 2-wire horn strobe alarm appliance that provides 4
selectable candela settings (15, 30, 75, 95). Siemens Audible Strobe
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 connected to a
notification appliance circuit running the Siemens sync protocol. The
AS-MC-C Appliance is UL Listed under Standard 1971 for Emergency
Appliances for the Hearing Impaired and UL Standard 464 for Audible
Signal Appliances. This appliance is listed for
ceiling mounting and
indoor use only
and is equipped with a universal mounting plate
(UMP) that can be mounted to single-gang, double-gang, 4” backbox,
or 100mm European backbox (See wiring and mounting information).
The AS-MC-C Appliance uses a xenon flashtube with solid state
circuitry enclosed in a polycarbonate lens to provide maximum
visibility and reliability for effective visible signaling.
The AS-MC-C Appliance can be field set to provide either high (HI)
dBA, 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.
This model is designed for use with either filtered DC (VDC) or
unfiltered Full-Wave-Rectified (FWR) input voltage. All inputs are
polarized for compatibility with standard reverse polarity supervision of
circuit wiring by a (FACP).
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.

NOTES:
1. Strobe will produce 1 flash per second over the Input Voltage range.
2. This strobe/horn model meets the required light distribution patterns defined in UL 1971.
3. This model is UL Listed for indoor use with a temperature range of +32ºF to +120ºF (0ºC to +49ºC) and maximum humidity of 93% + 2% RH. The
effect of shipping and storage temperatures shall not adversely affect the performance of the appliance when it is stored in the original cartons and
not subjected to misuse or abuse.
When calculating the total current: Use Table 3 to determine the highest value of “RMS Current” for an individual AS Appliance then multiply the value
by the total number of AS Appliances. Be sure to add the currents for any other appliances powered by the same source and include any required
safety factors.
CANDELA SETTING WILL DETERMINE THE CURRENT DRAW OF THE PRODUCT.
THESE APPLIANCES WERE TESTED TO THE VOLTAGE LIMITS OF 16.0-33.0 VOLTS FOR 24V MODELS USING FILTERED DC OR
UNFILTERED FULL-WAVE-RECTIFIED VOLTAGE. DO NOT APPLY VOLTAGE OUTSIDE OF THIS RANGE.
Note: Refer to the installation instructions for the appropriate NAC to find the maximum allowed voltage drop. Use this value along with the current
draw for the appliance to determine the allowable wire resistance. The maximum wire resistance between strobes shall not exceed 35 ohms.
This appliance is not designed to be used on coded systems in which the applied voltage is cycled on and off.
