Before Installing
Please thoroughly read the system wiring and installation
manuals and the System Smoke Detectors Applications
Guide, which provide detailed information on detector
spacing, placement, zoning, and special applications.
NOTICE: This manual should be left with the owner/user
of this equipment.
IMPORTANT: The detector used with these bases must be
tested and maintained regularly following NFPA 72 require-
ments. The detectors should be cleaned at least once a year.
General Information
Form C latching relay contacts are included for the control of
an auxiliary function. The relay can operate in two differnt
modes (short and long delay). The activation time when the
short delay is used is 60 msec to 100 msec, while the activa-

tion time for the long delay is 6 sec to 10 sec. A shunt with
pin headers, located on the base PC board, can be used to
choose your desired delay. B224RB is set at the short de-
lay when manufactured. If you wish to use the long delay,
please move the shunt to the adjacent pair of pin headers.
Mounting

- and 4-inch octagon
and 4-inch square boxes, with or without a plaster ring.
To mount, remove the decorative ring by rotating it in either
direction to unhook the snaps. Then, separate the ring from
the base. Install the base on the box, using the screws sup-
plied with the junction box and the appropriate slots in the
base. Replace the decorative ring on the base and rotate it in
either direction until the ring snaps in place (see Figure 1).
