Before Installing

Please thoroughly read the system wiring and installation manuals, and manual I56-407, Guide for Proper Use of Sys- tem Smoke Detectors, which provides detailed information on detector spacing, placement, zoning, and special appli- cations. Copies of these manuals are available at no charge from System Sensor. (For installation in Canada, refer to CAN/ULC-S524, Standard for the Installation for 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 these bases must be tested and maintained regularly following NFPA 72 require- ments. The detectors should be cleaned at least once a year.

General Information

Form C latching relay contacts are included for the control of an auxiliary function. The relay operates 12 seconds (nominally) after activation of the sensor head remote an- nunciator output.

Mounting

The detector base mounts directly to 31/2- and 4-inch oc- tagon and 4-inch square boxes, with or without a plaster ring.

To mount, remove the decorative ring by rotating it in ei- ther direction to unhook the snaps. Then, separate the ring from the base. Install the base on the box, using the screws supplied with the junction box and the appropriate slots in the base. Replace the decorative ring on the base and ro- tate it in either direction until the ring snaps in place (see Figure 1).

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.
