3.4.5 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 16VAC
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
depressed.
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 will flash
repeatedly, until the communication problem has been resolved.
