Please read the System Smoke Detector Applications Guide, which provides
detailed information on detector spacing, placement, zoning, wiring, and spe-
cial applications. Copies of this application guide are available from System
Sensor. NFPA 72 guidelines should be observed.
NOTICE: This manual should be left with the owner/user of this equipment.
IMPORTANT: The detector used with these bases must be tested and main-
tained regularly following NFPA 72 requirements. The detectors should be
cleaned at least once a year.

The relay base is intended for use in an intelligent system. Form C latching
relay contacts are included for the control of an auxiliary function. The relay
can operate in two different modes (short and long delay). The activation time
when the short delay is used is 60 msec to 100 msec, while the activation 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 delay when manufactured. If you wish to use the long delay, please
move the shunt to the adjacent pair of pin headers. See Figures 2 and 6.

Mount the mounting plate directly to an electrical box. The plate will mount
directly to 4-inch square (with and without plaster ring), 4-inch octagon, 3
½-inch octagon, single gang and double gang junction boxes.
1. Connect field wiring to terminals, as shown in Figure 4.
2. Attach the mounting plate to the junction box as shown in Figure 2.
3. To mount the base, hook the tab on the base to the groove on the
mounting plate.
4. Then, swing the base into position to engage the pins on the product
with the terminals on the mounting plate.
5. Secure the base by tightening the mounting screws.
6. Install a compatible smoke detector as described in the installation
manual for the detector.
