WARNING: THE CANDELA SELECT SWITCH MUST BE FIELD SET TO THE REQUIRED CANDELA INTENSITY BEFORE INSTALLATION. WHEN CHANGING
THE SETTING OF THE CANDELA SELECT SWITCH, MAKE CERTAIN THAT IT “CLICKS” IN PLACE. AFTER CHANGING THE CANDELA SETTING, THE
APPLIANCE MUST BE RETESTED TO VERIFY PROPER OPERATION. IMPROPER SETTING OF THE CANDELA SELECT SWITCH MAY RESULT IN OPERATION
AT THE WRONG CANDELA, WHICH COULD RESULT IN A CURRENT DRAW EXCEEDING THE POWER SUPPLY’S CAPACITY.
MULTITONE SETTINGS:
The Switch (SW1) of the Multitone Appliance, shown in Figure 2, is used to set the dBA sound output level and alarm tone. The factory settings are shown below.

STEP 1:
Set desired dBA sound output level as follows (Refer to Figure 3). Multitone Strobe Appliances cannot be field set for input voltage. Multitone Strobe Appliances are
field set for dBA sound output level by adjusting a four position Switch (SW1) as shown in Table 5 and Figure 2. Use SW1 Position 1 to select the dBA sound output
level.
