Temperature Range:
Under no circumstances can the PS24 voltage exceed 33VDC or be less than 18VDC.
Under no circumstances can the PS12 voltage exceed 18.7VDC or be less than 9.6VDC.
To calculate battery requirements, use current values shown above. However, note that there is an in-rush current associated with
strobe power-up. The information in Figures 3 and 4 is useful when selecting fuse values.
As Figure 3 shows, 12V strobe in-rush current typically peaks at 3A and drops to nominal in 600µS. In a 24V strobe (Figure 4), in-rush
current typically peaks at 7.0A and drops to nominal in 800µS.
Note: If class "A" wiring is installed, the wire length may be up to 4 times the single wire length in this calculation.

General Information

The National Fire Protection Association has published codes,
standards, and recommended practices for the installation and
use of the above appliances. Therefore, the installer must be
familiar with these requirements, with local codes, and any spe-
cial requirements of the authority having jurisdiction.

Installation Notes

The wiring must be in compliance with all codes and must not be
of such length or wire size that would cause the appliance to
operate outside of its published specifications. The appliances
must also be tested after installation in accordance with the con-
trol panel manufacturer's test procedure.
NOTE: Do not loop wires under terminal screws. Wires connect-
ing the device to the panel must be broken at the device
screw terminal in order to maintain electrical supervision.
