Strobe Installation Sheet
Description
The DC-M9415 Series Wall Mount Strobe is a visible fire alarm
notification appliance that is designed for mounting on indoor walls.
See Table 1 for a list of model numbers.
2. Slide the candela switch to the desired candela output (15, 30, 75,
or 110 cd) by aligning it with the indicator located beside the
switch. See Figure 1.
3. Set the strobe signal if required. See Figure 2.
4. Connect the strobe terminals to the signal circuit field wiring. You
must observe polarity for the unit to function properly. See
Figure 3.
5. Mount the unit onto a compatible electrical box, making sure not to
over-tighten the mounting screws.
6. Replace the cover by aligning at the bottom, then snapping in at
the top.
7. Test the unit for proper operation.

The strobe includes a field-configurable switch for selecting the desired
candela output and a field-configurable jumper for the strobe signal
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-M9415
Series Wall Mount 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 breaking the wire run at each
terminal. Do not loop the signaling circuit field wires around the
terminals.
To install the strobe:
1. Remove the cover by depressing both tabs on the top of the unit
with a small screwdriver and twisting slightly.

(1) To change the strobe to temporal (private mode), cut from circle J1
to the edge of circuit board.
Note: If the strobe is set to temporal (private mode), this device is no
longer UL 1971 listed, but is UL 1638 listed.
