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.
