B110RLP

NOTE: Do not use the tamper-resistance feature if the XR2 removal tool is to be used.

The tamper-resistant tab, in the detector mounting bracket, can make the detector tamper-resistant by making it necessary to use a small screwdriver or similar tool to detach theM detector from the bracket.

Figure 2. Typical wiring diagram for 2-wire detector systems:
A78-1175-05 To make the detector tamper-resistant, use needle-nose pliers to break the smaller tab at the scribed line on the tamper- resistance tab. Figure 3A shows the location of this tab on the detector mounting bracket.

To remove a detector from the bracket after it has been made tamper resistant, use a small screwdriver or other similar tool, to depress the tamper-resistance tab in the slot on the mounting bracket, and rotate the detector counterclockwise (see Figure 3B).

NOTE: The decorative ring must be removed before the smoke detector can be detached from the base after the tamper-resistant capability is enabled.

The B110RLP plug-in detector base is used with System Sensor model 1151 and 1151A ionization detector heads and model 2151 and 2151A photoelectronic 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.

This B110RLP is intended for use in 2-wire systems, with screw terminals provided for power, ground, and remote annunciator connections. The base also contains a resistor to provide current limiting in the alarm state.
