4.8 BL-D40 External Sounder
The BL-D40 external sounder is designed for indoor use only and
installed within the secured premises. The sounder can be powered by
a 12 to 24 VDC power supply or by a 16 VAC transformer. The
BL-D40 is capable of emitting four different types of audible and
visual alerts: bell, chime, siren and strobe light.
The bell sounds when the controller’s bell button is pressed.
The door chime can be programmed to sound whenever a valid
code is entered as well as for a door held open alert.
The siren can be programmed to sound when the controller is
tampered with (opened or removed from the wall). The length of
the siren can also be programmed in the controller.
The controller communicates with the BL-D40 via a Rosslare
proprietary protocol. If the BL-D40 receives an unrecognized code
over its communication line or communications between the
controller and the BL-D40 are severed, the strobe flashes repeatedly,
until the communication problem has been resolved.
