Fire-Lite B224RB Relay Base - Ivory

Fire-Lite B224RB Relay Base

Available in Ivory and White 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. The relay base is intended for use in an intelligent system. Form C latching relay contacts are included for the control of an auxiliary function. The relay can operate in two different modes (short and long delay). The activation time when the short delay is used is 60 msec to 100 msec, while the activation time for the long delay is 6 sec to 10 sec. A shunt with pin headers, located on the base PC board, can be used to choose your desired delay. B224RB relay base in ivory is set at the short delay when manufactured. If you wish to use the long delay, please move the shunt to the adjacent pair of pin headers. See Figures 2 and 6.
