THREE-YEAR LIMITED WARRANTY
System Sensor warrants its enclosed smoke detector base to be free from defects in ma-
terials and workmanship under normal use and service for a period of three years from
date of manufacture. System Sensor makes no other express warranty for this smoke
detector base. No agent, representative, dealer, or employee of the Company has the au-
thority to increase or alter the obligations or limitations of this Warranty. The Company’s
obligation of this Warranty shall be limited to the replacement of any part of the smoke
detector base which is found to be defective in materials or workmanship under normal
use and service during the three year period commencing with the date of manufacture.
After phoning System Sensor’s toll free number 800-SENSOR2 (736-7672) for a Return
Authorization number, send defective units postage prepaid to: System Sensor, Returns
Department, RA #__________, 3825 Ohio Avenue, St. Charles, IL 60174. Please include
a note describing the malfunction and suspected cause of failure. The Company shall
not be obligated to replace units which are found to be defective because of damage,
unreasonable use, modifications, or alterations occurring after the date of manufacture.
In no case shall the Company be liable for any consequential or incidental damages for
breach of this or any other Warranty, expressed or implied whatsoever, even if the loss
or damage is caused by the Company’s negligence or fault. Some states do not allow the
exclusion or limitation of incidental or consequential damages, so the above limitation
or exclusion may not apply to you. This Warranty gives you specific legal rights, and you
may also have other rights which vary from state to state.

BEFORE INSTALLING
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.
GENERAL INFORMATION
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.

MOUNTING
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.

INSTALLATION GUIDELINES
All wiring must be installed in compliance with all applicable local codes and
any special requirements of the local authority having jurisdiction, using the
proper wire sizes. The conductors used to connect smoke detectors to control
panels and accessory devices should be color-coded to reduce the likelihood
of wiring errors. Improper connections can prevent a system from responding
properly in the event of a fire.
For signal wiring (the wiring between interconnected detectors), it is recom-
mended that the wire be no smaller than 18 gauge (0.9 square mm). However,
wire sizes up to 12 gauge (2.5 square mm) can be used with the base.
Alarm system control panels have specifications for allowable loop resistance.
Consult the control panel specifications for the total loop resistance allowed
before wiring the detector loops.
WIRING INSTRUCTIONS
WARNING
The base uses a latching relay that can change states if it is subjected to me-
chanical shocks or jarring. As a result, even though relay contacts are in the
open state when the base is shipped from the factory, the contacts may have
closed during shipment.
Connecting an auxiliary control circuit to closed relay contacts can cause an
unexpected, and possibly dangerous, activation of that circuit. Therefore, do
NOT connect an auxiliary control circuit to the relay contacts (terminals 1, 2,
and 3) before ensuring that the relay contacts are in their open state. Ensure
that the contacts are open by applying power to the bases WITHOUT the sen-
sor heads installed.
Make wiring connections by stripping about 3⁄8"(10 mm) of insulation from
the end of the wire. Then, slide the wire under the clamping plate and tighten
the clamping plate screw.
Wire the normally open (NO) line to terminal 3 (see Figure 4). Insert the nor-
mally closed (NC) line of the relay to terminal 1 and the relay common line
to terminal 2. Wire the communication lines in (–) and out (–)to terminal 4.
Insert the communication line in (+) and out (+) to terminal 5.
Check the zone wiring of all bases in the system before installing detector
heads. This includes checking the wiring for continuity, correct polarity,
ground fault testing, and performing a dielectric test.
A label is affixed to the base for recording the zone, address, and type of
detector being installed at the base location. This information is useful for set-
ting the detector head address and for verification of the sensor type required
for that location.
Once all detector bases have been wired and mounted, and the loop wiring
has been checked, the detector heads may be installed in the bases.
TAMPER-RESIST FEATURE
NOTE: Do not use the tamper-resist feature if the removal tool is to be used.
This detector base includes a tamper-resist feature that prevents its removal
from the base without the use of a tool.
To activate this feature, break the tab from the detector base as shown in Fig-
ure 5A. Then, install the detector.
To remove the detector from the base once the tamper-resist feature has been
activated, insert a small-bladed screwdriver into the slot from the top and
press down on the lever (see Figure 5B). This allows the detector to be rotated
counterclockwise for removal.
The tamper-resist feature can be defeated by breaking and removing the plas-
tic lever from the base. However, this prevents the feature from being used
again.
