Field-configurable jumper options are available for selecting the
desired dB output, temporal or steady sound output, and strobe signal
output.
The sounder strobe includes a field-configurable switch for selecting
the desired candela output. The candela output setting is locked in
place and remains visible after final installation.
This strobe features an enhanced synchronization circuit to comply
with the latest requirements of UL 1971
Signaling Devices for the
Hearing Impaired
.
Synchronized operation requires that you connect the DC-M9416
Series Ceiling Mount Sounder Strobe to a NAC output set for Synch
Mode, or to a separate DC-M9410 Signal Synchronization Module.
Installation
Install and wire this device in accordance with applicable national and
local codes, ordinances, and regulations.
WARNING:
Electrocution hazard. To avoid personal injury or death
from electrocution, remove all sources of power and allow 10 minutes
for stored energy to discharge before installing or removing equipment.
Caution:
Electrical supervision requires the wire run to be broken at
each terminal. Do not loop the signaling circuit field wires around the
terminals.

1. Remove the cover by depressing the tab on the side of the unit
with a small screwdriver. Turn the cover counterclockwise to
release.
2. Set the sounder signal, sound output level, and strobe signal to the
desired settings. See Figure 1.
3. Connect the strobe terminals to the signal circuit field wiring. You
must observe polarity for the unit to function properly. See
Figure 3.
4. Slide the candela switch to the desired candela output (95, 115,
150, or 177 cd) by aligning it with the indicator below the switch.
See Figure 2.
5. Mount the unit onto a compatible electrical box. See Figure 4.
6. Replace the cover by positioning the alignment arrows together
and rotating the cover clockwise.
7. Test the unit for proper operation.
