Fire-Lite B501-BL 4″ Standard European Flangeless Mounting Base, UL/ULC Listed, Black

Description

To meet local code and application requirements, Fire-Lite offers standard 4″ and 6″ bases, as well as, specialty base designs including relay, isolator, sounder and low frequency sounder options for the new 365 Series of addressable detectors as well as previous generations

The standard 4″ and 6″ bases offer a plug-in detector base intended for use in intelligent systems, with screw terminals provided for power (+ and -), and remote annunciator connections. Communication takes place over the power (+ and -) lines. The 4″ base offers a compact design while the 6″ base provides compatibility with a wider range of junction boxes.

The specialty bases support application driven requirements. These bases employ a separate mounting plate that installs on various junction box sizes to eliminate unsightly surface-mount boxes. The mounting plate enables pre-wiring of all connections to speed and simplify installation.

Relay bases (B224RB-WH/B224RB-IV) provide one form-C contact relay for control of auxiliary functions, such as door closure and elevator recall. The relay can operate in two different modes (short and long delay). The activation time for the short delay is 60-100 milliseconds, while the activation time for the long delay is 6-10 seconds. A shunt with pin headers, located on the base PC board, is used to set the delay timing.
