Mounting
Reversible strobe module
Should the back box be located near an obstruction such as
a doorway, the strobe module is field-reversible (Fig. 3).
To reverse the strobe module: insert screwdriver, as shown
in Fig. 3, to unlock snap. While pushing in the screwdriv-
er, pull back on the strobe module. Hinge the strobe mod-
ule, disengage the Locking Rib and lift the module away
from the mounting plate. Turn the module so that it is
upside down from its original position, re-insert the mod-
ule into the mounting plate (be sure to insert the Locking
Rib into the slot), and press the module into the mounting
plate. The strobe module will make a “click” when it has
locked into place. Turn the entire assembly so that the word
“FIRE” is right side up. The unit can now be mounted.
