Chime Strobes provide low current draw, choice of
single-strike or vibrating operation, adjustable sound
level, chime tone adjustable from 800 Hz to 1200 Hz, and
choice of four light output intensities (15 cd, 30 cd,

Functions
Strobe Settings
The unit comes set at 15 cd. Change the setting using a
screwdriver in the slot in the unit's base (setting is
visible on indicator plate within the lens).
Volume and Tone Settings
The volume and tone controls are factory set to ensure
maximum dBA output; however, the volume and tone
can be tuned to suit a particular application. Take
appropriate measurements to ensure the volume meets
the listing requirements for private mode fire protective
service per UL464.
Sound Mode Settings
The chimes are factory set in single-stroke mode. They
can be changed to vibrating mode before wiring by
moving a jumper.
Single-Stroke Mode
The minimum input pulse duration must be at least
160 ms on and 160 ms off. The chime only operates once
each time it is pulsed. Use this mode for coded systems.
Vibrating Mode
Apply continuous input voltage to the chime to activate
the chime at 1 sec intervals.
