Before installing and using the product, please read the system
wiring and installation manual thoroughly. If the products will
be installed in an existing operational system, inform the
operator and local authority that the system will be temporarily
out of service, disconnect power to the control panel before
installing the products.
NOTICE: This manual should be left with the owner/user of this
equipment.
IMPORTANT: The detector used with this base must be tested and
maintained regularly following GB and UL Standard requirements.
The detector used with this base should be cleaned at least once a
year.
GENERALDESCRIPTION
This B401-WP plug-in detector base is used with System Sensor
smoke and heat detector heads. The capability of plugging these
detectors into a variety of special bases makes them more
versatile than equivalent direct-wired models. Refer to the System
Sensor catalog for other available plug-in detector bases. The
B401-WP base is intended for use in 2-wire systems with screw
terminals provided for power and remote annunciator connections.
MOUNTING
This detector base mounts directly to 60 mm junction boxes.
Install the base to the box using the screws supplied with the
junction box and the appropriate mounting slots in the base as
Figure 1 showed.
INSTALLATION GUIDELINES
All wiring must be installed in compliance with applicable codes
and the authority having jurisdiction. Proper wire gauges should
be used. 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 recommended that the wire be no smaller than 18gauge. Wire
sizes up to 12gauge may be used with the base. For best system

performance, the power (+) and (–) loop wires should be twisted
pair and installed in separate grounded conduit to protect the loop
from extraneous electrical interference. Smoke detectors and alarm
system control panels have specifications for allowable loop resistance.
Consult the control panel manufacturer's specifications for the total
loop resistance allowed for the control panel being used before wiring
the detector loops.

WIRING INSTRUCTIONS
CAUTION: Do not loop wire under terminals. Break wire run to
ensure supervision of connections. To penetrate the hole with the
screwdriver on the base when to wire. Then, make the wire through
the hole (see Figure 3). Wire connections are made by stripping about
3/8" of insulation from the end of the wire (use strip gauge molded in
base), sliding the bare end of the wire under the clamping plate, and
tightening the clamping plate screw.

Two-wire initiating devices receive their power from the initiating circuit of a control panel. Electrical specifications of the control panel and
the detector-base combination must be compatible for the system to function properly. System Sensor maintains a list of two-wire detectors
and control panels that are listed as compatible. The 2-Wire Compatibility Chart is available from System Sensor. The zone wiring of the
detector bases should be checked before the detector heads are installed. To make this possible, this base contains a special spring-type
shorting jumper (shown in Figure 1). After a detector base is properly wired and mounted to an electrical box, make sure that the shorting
spring is in contact with terminal 3. This temporary connection permits the wiring of the loop to be checked for continuity before installation
of the detector heads. The shorting spring in the base automatically disengages when the detector head is removed from the base. DO NOT
remove the shorting spring since it reengages as the detector head is turned in the base, completing the circuit.
TAMPER-RESISTANT FEATURE
This detector includes an optional tamper-resistant feature that
prevents its removal from the base without the use of a tool. To
make the detector tamper-resistantance, remove the smaller tab by
breaking it at the scribed line on the tamper-resistant tab before
installing the detector (see Figure 4A). The tamper-resistant tab is
on the detector mounting base. To remove a tamper-resistant
detector from the base, use a pocket screwdriver, or similar tool, to
depress the tamper-resistant tab and turn the detector counterclockwise.
The tab is accessible through the slot on the mounting base (see
Figure 4B).
The tamper-resistant feature can be defeated by breaking and removing
the plastic lever from the base. However, this permanently disables the
tamper-resistant feature.
