INSTALLATION INSTRUCTIONS

SUPERVISED SELF-AMPLIFIED SPEAKER

Use this product according to this instruction manual. Please keep this instruction manual for future reference.

MODEL NUMBERS:

Speaker SA-S70-R Supervised Self-Amplified Speaker
Speaker SA-S70-W Supervised Self-Amplified Speaker
Speaker SA-S90-R Supervised Self-Amplified Speaker
Speaker SA-S90-W Supervised Self-Amplified Speaker

GENERAL:

The Supervised Self-Amplified Speaker provides a choice of 6 different sound output levels and operates with audio input levels of

0.5 VRMS (e.g., from Wheelock’s SALL-15S or any other 0.5V-RMS audio output source Listed for Fire Protective Signaling
Service) and 25 VRMS, all 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. The appliance mounts onto a 4” square deep backbox with an extension ring. (See Mounting
Options.) All inputs are polarized for compatibility with standard reverse polarity supervision of circuit wiring via a Control Panel.

NOTE: All CAUTIONS and WARNINGS are identified by the symbol

. All warnings are printed in bold capital letters.

WARNING: THE SPEAKER APPLIANCE IS A "FIRE ALARM DEVICE - DO NOT PAINT."

WARNING: PLEASE READ THESE INSTRUCTIONS CAREFULLY BEFORE USING THIS PRODUCT. THE
SUPERVISED SELF-AMPLIFIED SPEAKER MUST BE FIELD SET TO THE DESIRED SOUND OUTPUT LEVEL
BEFORE IT IS INSTALLED. THIS IS DONE BY PROPERLY ADJUSTING A FOUR-POSITION SWITCH IN
ACCORDANCE WITH THESE INSTRUCTIONS. INCORRECT SETTINGS WILL RESULT IN IMPROPER
PERFORMANCE AND MAY DAMAGE THE PRODUCT, WHICH COULD RESULT IN PROPERTY DAMAGE AND
SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS.

WARNING: 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 APPLIANCES.

NOTE: See Table 3 Sound Output Level Selection for use of settings “A” and “B”.

Power Input Voltage: 16.0 to 33.0 VDC, regulated
Current Consumption: 120 mA RMS maximum
Appliance Input Level: 0.5 V RMS or 25 V RMS (Switch selectable)

Appliance Input Impedance: 0.5-V Setting:

Greater than 400 Ohms, or equivalent to less than
1/1000 W (0.001 W or 1 mW) load

25-V Setting:
Greater than 20 kOhms, or equivalent to less than
1/32 W (0.03125 W or 31.25 mW) load

Sound pressure level measurements were made at 16 VDC with audio inputs of 0.5 V RMS in the 0.5-V setting and with 25 V RMS
in the 25-V setting. Current measurements were made at 33 VDC with audio inputs of 0.5 V RMS in the 0.5-V setting and with
25 V RMS in the 25-V setting.

WARNING: THIS APPLIANCE WAS TESTED TO THE OPERATING VOLTAGE LIMITS OF 16-33 VOLTS
REGULATED POWER. DO NOT APPLY 80% AND 110% OF THESE VOLTAGE VALUES FOR SYSTEM OPERATION.

CAUTION: The Speaker is not designed to be used on coded systems in which the applied voltage is cycled on and off.

SETTINGS:

The switch on the PCB (SW1) is used to select the input voltage and sound output level, see Figure 1.
