3.3 Installation of the Horn/Strobe
1. The horn/strobe/s must be installed on the wall above the O2 sensor, approximately 2-2.4
m/80-96 inches (as per NFPA 72) above the floor, clearly visible from any entrance of the area
being monitored. It is recommended that a second horn/strobe be placed OUTSIDE the area being
monitored, preferably placed over the door/s leading to the monitored area. This will require more
than one horn/strobe. Mount the unit with supplied mounting screws.
2. Mount the included warning signs so they are clearly visible, next to or above the horn/strobes, in a
permanent way.
3.4 Installation of the Central Unit
1. If your set includes a central unit, it must be installed outside the area or room being monitored, for
example on a wall in the manager’s office. The central unit must be installed at a clearly visible and
reachable height.
2. Mount the included information signs clearly visible, next to or above the units, in a permanent way.
