Start-up Time (after 60 second reset):  
nect 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.  
BEfORE INSTALLINg  
Please thoroughly read the System Sensor manual I56-407, Guide for Proper  
Use of System Smoke Detectors. This manual provides detailed information on  
detector spacing, placement, zoning, wiring, and special applications, and is  
available at no charge from System Sensor. (For installation in Canada, refer to  
CAN/ULC-S524, Standard for the Installation of Fire Alarm Systems and CEC  
Part 1, Sec. 32.)  
For signal wiring (the wiring between interconnected detectors), it is recom-  
mended that the wire be no smaller than AWG 18. However, the screws and  
clamping plate in the base can accommodate wire sizes up to AWG 12. The  
use of twisted pair wiring for the power (+ and –) loop is recommended to  
minimize the effects of electrical interference.  
NOTICE: This manual should be left with the owner/user of this equipment.  
fIgURE 1. TERMINAL LAyOUT:  
IMPORTANT: The detector used with this base must be tested and maintained  
regularly following NFPA 72 requirements. The detector used with this base  
should be cleaned at least once a year.

The model B114LP detector base is designed for use with System Sensor model  
2151 photoelectronic and 1151 ionization detector heads. This four-wire base is  
equipped with screw terminals for the connection of power, ground, relay connec-  
tions, and an optional RA400Z remote annunciator. It also includes a resistor that  
limits current when the associated smoke detector is in the alarm state.

The detector base mounts directly to 31/2-inch and 4-inch octagon boxes and  
4-inch square boxes, with or without plaster rings. To mount the base, remove  
the decorative ring by rotating it in either direction to unhook the snaps before  
separating the ring from the base. Use the screws supplied with the junction  
box to attach the base to the box through the appropriate slots in the base.

INSTALLATION gUIDELINES  
Allowable loop resistance is an important specification for control panels as  
well as for smoke detectors and their bases. The alarm system cannot be ex-  
pected to operate correctly if system components have incompatible allowable  
loop resistances. Therefore, before beginning installation, refer to the control  
panel manufacturer’s loop resistance specification to ensure that it is listed as  
compatible with the System Sensor base and smoke detector being installed.  
BOX  
(NOT SUPPLIED)  
All wiring must be installed in compliance with the National Electrical Code  
and all applicable local codes and any special requirements of the authority  
having jurisdiction, using the proper wire size. The conductors used to con-
