You can mount the D279A directly onto a wall, install it in a flush-mount unit, or attach it to a D55 Desk Stand (see the

special installation instruction sheet that comes with each item).

Do not mount the D279A in a location exposed to direct sunlight. Direct sunlight makes the LEDs less visible, and

intense heat can damage the D279A enclosure and electrical components.

Wiring between the D279A and the panel is not supervised: The wiring between the D279A and the panel is not supervised for

trouble conditions. Wiring between the D279A and remote sensing devices is supervised with end-of-line resistors.

1. Remove the front cover from the enclosure base (see Figure 1). Use a small flat-blade screwdriver to gently

push the two bottom cover tabs back. As the tabs are pushed back, lift the bottom of the cover away from the

base. Remove the cover.
