A label is affixed to the base for recording the zone, ad- dress, and type of detector being installed at the base loca- tion. This information is useful for setting the detector head address and for verification of the sensor type required for that location.

Once all detector bases have been wired and mounted, and the loop wiring has been checked, the detector heads may be installed in the bases.

Tamper-resist Feature

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

This detector base includes a tamper-resist feature that pre- vents its removal from the base without the use of a tool.

To activate this feature, break the tab from the detector base as shown in Figure 3A (see page 4). Then, install the detector.

To remove the detector from the base once the tamper-re- sist feature has been activated, insert a small-bladed screw- driver into the slot in the side of the base and push the plastic lever away from the detector head (see Figure 3B, page 4). This allows the detector to be rotated counter- clockwise for removal.

NOTE: Head removal after the tamper-resist feature has been activated first requires removal of the decora- tive ring.

The tamper-resist feature can be defeated by breaking and removing the plastic lever from the base. However, this pre- vents the feature from being used again.

B224RB(A), B524RB(A) specifications

System Sensor B224RB(A) and B524RB(A) are advanced, reliable devices designed for comprehensive fire alarm systems. These hard-wired smoke detectors are engineered for both commercial and residential applications, contributing to enhanced safety and protection against fire hazards.

One of the main features of the B224RB(A) and B524RB(A) models is their use of photoelectric sensing technology. This type of sensing is particularly effective in detecting smoldering fires that produce a large amount of smoke but little heat. The photoelectric sensor utilizes a light source that is aimed at a sensor; when smoke enters the chamber, it scatters the light, triggering an alarm. This technology is known for reducing false alarms commonly associated with traditional ionization smoke detectors.

Another significant feature is the built-in sounder that provides local alarm notification. This integrated sounder enhances the device's effectiveness in alerting occupants to potential danger, ensuring prompt action can be taken. The sounder can often be configured to emit different tones, allowing for customizable alerts based on the specific requirements of the environment.

The B224RB(A) and B524RB(A) also incorporate advanced communication capabilities, compatible with various alarm control panels, providing flexibility in integration within different fire alarm systems. They support both conventional and addressable modes, offering ease of installation and maintenance. The devices are equipped with a robust network of features that allow for simultaneous monitoring and reporting, ensuring that incidents are quickly identified and communicated.

In terms of characteristics, these detectors boast a durable design that withstands the rigors of various environments. They are built to operate efficiently in temperature ranges suitable for typical indoor settings, ensuring consistent performance over time. Additionally, they are designed to be user-friendly, with LEDs that provide visual alerts indicating the operational status, allowing users to quickly ascertain if the device is functioning correctly.

Overall, the System Sensor B224RB(A) and B524RB(A) smoke detectors represent a sophisticated solution for fire safety, combining cutting-edge technology with practical features to deliver reliable performance in safeguarding life and property from the dangers of fire.
