Specifications - Siemens AS Series Manual

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 Multi-Candela Audible Strobe Appliance (AS -MC) is the
industry's first 2-wire horn strobe alarm appliance that provides 4
selectable candela settings (15, 30, 75, 110). 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 when connected to
a notification appliance circuit running the Siemens sync protocol. The
AS-MC Appliance is UL Listed under Standard 1971 for Emergency
Appliances for the Hearing Impaired and UL Standard 464 for Audible
Signal Appliances. The AS-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. This appliance
is listed for wall 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, 100mm European backbox or SHBBS
surface backbox (See wiring and mounting information). The AS-MC
Appliance uses a xenon flashtube with solid state circuitry enclosed in

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 and ULC-S526-02.
3. This model is UL/ULC Listed for indoor use with a temperature range of +32  F to +120  F (0  C to +49  C) 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.
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.
