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.)

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 NFPA 72 requirements. The detector used with this base should be cleaned at least once a year.

General Description

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.

Mounting

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.

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.

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.

BASE

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.

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-
