the system will be temporarily out of service, disconnect power to the
control panel before installing the products.
NOTICE: This manual should be left with the owner/user of this
equipment.
GENERAL
LASS-WSS-NC is an intelligent addressable AV products designed to
alarm light/sound for emergency events, and be able to communicate
with control panel by intelligent protocol.
It is designed specifically for analogue addressable fire alarm system
and only can be connected to control panels with a compatible
proprietary analogue addressable communication protocol. It is
powered from the loop and can be controlled via the communication
protocol(s). The Wall Mount Version is compatible with B501 mounting
base. Up to 99 addresses are available via two rotary selector
switches. The sounders have 2 volume levels (high/low) and 4 tone
sets. The alarm light/sound can be tested on field.
INSTALLATION
It must be installed and wired with B501 mounting base.
1. Verify the product type matches with product drawing.
2. Set the address via two rotary selector switches. Please refer to
“Address setting”.
3. Volume and tone setting are realized by 4 digit DIP switch. On field
testing can be tested via DIP switch.
4. Plug the Sounder base into B501 mounting base.
5. Turn the Sounder base clockwise until it drops into place.
6. Continue turning the Sounder base clockwise to lock it in place.
SETTING
Address setting
Rotary-decade switches are provided for setting the base’s address
whose range is from 1 to 99. (Default address is 01).
Address is set by turning the switches.
Address is calculated as below formula: Address = TENS *10 +
ONES*1. For instance: Address 05 = 0*10 + 5*1.
Tamper-resistant capability
Addressable Base sounder include a tamper-resistant capability that
prevents its removal from the B501 base and the removal of installed
detector without the use of a tool.

below figure: use straight screwdriver to break specific position, then
insert the screwdriver and maintain in its position. Then you can
disassemble the Sounder base by turning anticlockwise
Figure 3
Synchronization
