Use this product according to this instruction manual. Please keep this instruction manual for future reference.
GENERAL:
The Supervised Self-Amplified (SA) Speaker is UL Listed under Standard UL1480 (Speakers for Fire Alarm and Signaling Systems). The
SA Speaker is for indoor fire protection service and provides a choice of 6 different sound output levels and operates with audio input
levels of 0.5 V RMS and 25 V RMS by means of selectable switch settings. The Low Profile design incorporates a high efficiency
speaker for maximum output at minimum power across a frequency range of 400Hz to 4000Hz, and features a sealed back construction
for extra protection and improved audibility. All inputs are polarized for compatibility with standard reverse polarity supervision of circuit
wiring via a Control Panel.
The SA Speaker appliance is listed for indoor use with the backboxes specified in these instructions (see Mounting Options). The SA
Speaker will flush mount onto a 4” square deep backbox with an extension ring, or surface mount using the SBB backbox.
CAUTION: Do not change factory applied finishes. “DO NOT PAINT”.

When calculating the total currents: Use Table 1 to determine the highest value of “RMS Current” for an individual appliance, then
multiply these values by the total number of appliances; be sure to add the currents for any other appliances powered by the same source
and include any required safety factors.
Make sure that the total RMS current required required by all appliances that are connected to the system’s PRIMARY and SECONDARY
power sources, NAC circuits, DSM Sync Modules or Wheelock Power Supplies does not exceed the power sources’ rated capacity or the
current ratings of any fuses on the circuits to which these appliances are wired.
Check the minimum and maximum output of the power supply and standby battery, and subtract the voltage drop from the circuit wiring
resistance to determine the applied voltage to the appliance.

(Wiring must be all power-limited or all non-power-limited)
NOTES:
1.
Reverberant dBA is a minimum UL rating based on sound measurements in a reverberant test room.
2.
The SA Speaker is not designed to be used on coded systems in which the applied voltage is cycled on and off.
3.
This appliance does not generate a temporal pattern signal. If the distinctive three-pulse temporal pattern Fire Alarm Evacuation (or
total evacuation) in accordance with NFPA 72, is required, the control unit must be used with appliances that can generate the
temporal pattern signal. Refer to manufacturer's instruction manual for details.
