BL-D40 External Sounder
22 AC-A4x Installation and Programming Manual
10. BL-D40 External Sounder
The BL-D40 External Sounder is compatible with the AC-x31, AC-x32,
AC-x41, and AC-x42 series of standalone controllers. (For a more up-
to-date list of compatible products, check the Rosslare website at
www.rosslaresecurity.com.) It is designed to operate indoors and is
installed within the premises to be secured. The sounder can be
powered by a 16 VAC or 12 to 24 VDC power supply.
The BL-D40 is capable of emitting four different types of alerts, both
audible and visual: Bell, Door Chime, Siren, and Strobe Light.
The bell always sounds when the controller's doorbell button is
pressed.
The door chime can be programmed to sound whenever the
controller unlocks the door (the door chime does not sound when
the REX button is used to open the door).
The siren can be programmed to sound when the case of the
controller is opened or when the controller is removed from the
wall. The controller can also program the length of the siren in
the BL-D40.
The controller communicates with the BL-D40 using a coded
proprietary Rosslare communications protocol. This provides a more
secure link between the controller and the BL-D40. If the BLD40
receives any unrecognized codes on its communication line, or
communication between the controller and the BL-D40 are severed,
the strobe flashes repeatedly until the communication problem is
resolved.
