Strobe Light Ratings
The signaling strobe is rated for 0° to 49° C and is not suit-
able for outdoor use.
See Figure 3. The light output of the SP10**24LO is 1.5 cd
minimum when it is viewed from the front. The light out-
put of the SP10**24M is 15 cd minimum when it is viewed
from the front.

Model Description
Number
speaker w/ strobe
speaker w/ strobe
SP100 = Round grille speaker
SP101 = Square grille speaker
W = white
R = red
24 = 24 Volt Strobe
LO = 1.5 candela strobe
M = 15 candela strobe
Under no circumstances can the strobe input voltage ex-
ceed 33 VDC or be less than 18 VDC.
To calculate battery requirements, use the current values
shown in Table 2. However, note that there is an in-rush
current associated with strobe power-up. This information
may be used in consideration of fuse selection.
For the 24V strobe, as shown in Figure 4, the in-rush cur-
rent typically peaks at 7.0A, then drops to nominal in
800µS.
