General Information
Form C latching relay contacts are included for the control
of an auxiliary function. The relay operates 12 seconds
(nominally) after activation of the sensor head remote an-
nunciator output.
Mounting
The detector base mounts directly to 3
tagon and 4-inch square boxes, with or without a plaster
ring.
To mount, remove the decorative ring by rotating it in ei-
ther direction to unhook the snaps. Then, separate the ring
from the base. Install the base on the box, using the screws
supplied with the junction box and the appropriate slots in
the base. Replace the decorative ring on the base and ro-
tate it in either direction until the ring snaps in place (see
Figure 1).
