Addressable Voice Sounders & VADs
Product Description
The CAST Base Mount Voice range of addressable, loop-powered bases includes voice sounders
and combined voice sounder visual alarm devices (VADs). Their purpose is to visually and audibly
alert building occupants of a fire alarm. They are designed for use with C-TEC's CAST XFP/ZFP
panels and other `CAST' compatible fire panels.
The following variants are available:
Part Number Description
CA454A/W Addressable Ceiling Voice Sounder Base with isolator, white (CAST)

CA455A/W Addressable Ceiling Voice Sounder VAD Base with isolator, white, O-Class (CAST)
CA457A/W Addressable Ceiling Voice Sounder VAD Base with isolator, white, C-Class (CAST)
All CAST base devices can be optionally used as either:
- a stand-alone base using a separately available locking white cap (BF330CTLIDW) /
red cap (BF330CTLIDR) / black cap (BF330CTLIDB), or
- a combined, base device and CAST detector (CAST detectors are separately available).
The devices offer low current consumption, high sound output, high efficiency VADs, four
selectable volume levels, six selectable messages with tones and built-in short-circuit loop
isolators. Please note the volume levels and messages/tones can be changed using the panel's
programming tools.
The sounder and VAD on the combined devices (CA455A/W and CA457A/W) can be set to operate
independently of each other (panel dependent function).
The devices are designed to comply with all relevant sections of the fire alarm device standards
EN 54-3 (Sounders), EN 54-23 (Visual alarm devices - VADs) and EN 54-17 (Short-circuit isolators).
Mounting the Base Device
THE SYSTEM MUST BE COMPLETELY POWERED DOWN BEFORE INSTALLATION
Ensure the base devices are installed in accordance with applicable local or national regulations.
All bases are designed for ceiling mounting, indoor use only. Do not mount bases on uneven
surfaces.
CA454A/W and CA457A/W may be mounted in any orientation, whilst 'O-Class' CA455A/W must
be mounted with its lens pointing directly down the length of the corridor.
The base device has screw terminals for the loop cable (see `CAST Loop Connections΄ section) and
includes rear mounting slots for standard electrical termination boxes. Securely fix the base device
to a ceiling using two screws in the mounting slots provided.
Note: A Quick Connect Plate (Part No. BF431QCP) may be used as an accessory to assist with
cabling to the base device (refer to BF431QCP Document No. DFU4310020 for details).
