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 connections, 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. Position the decorative ring around the base and rotate it in either direction until the ring snaps into place (see Figure 2).

nect smoke detectors to control panels and accessory devices should be colorcoded 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 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. fIgURE 1. TERMINAL LAyOUT:

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 expected 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.

WIRINg INSTRUCTIONS NOTE: Refer the manufacturer's instructions for releasing device wiring. NOTE: To ensure that electrical connections are supervised, do NOT loop wires under terminals 8, 9, 10, and 11 - cut the wire at each terminal. To make electrical connections, strip approximately 3/8 inch (1 cm) insulation from the end of each wire. Slide a wire under the clamp plate on each side of the terminal screw and tighten the screw. If the base is being installed in a zoned system, check the zone wiring before installing the smoke detector head. The built-in shorting spring makes it convenient to do this. After the detector base is wired and attached to the electrical box, position the shorting spring against terminal 3. Use the slot in the retaining clip to hold the spring against the terminal, as shown in Figure 1. This shorts the negative-in and negative-out leads so that loop wiring can be tested for continuity. Do NOT remove the shorting spring from the base when continuity tests are completed. After all detector bases have been mounted, wired, and the wiring checked, install 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 headPLASTIC LEVER the base, is turned into completing the circuit.
This detector base can be made tamper resistant so the detector cannot be detached without the use of a tool. To make the base tamper resistant, break off the smaller tab at the scribed line on the tamper-resistance tab, on the detector mounting bracket (see Figure 4A), before installing the detector. To remove the detector from the base after it has been made tamper resistant, remove the decorative ring by rotating it in either direction and pulling it away from the base. Then, insert a small screwdriver (Figure 4B) into the notch and press the plastic lever toward the mounting surface. Rotate the detector counterclockwise and remove. fIgURE 4A.
