GENERAL
LASS-BSS-NC is an intelligent addressable AV base 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 Base version is compatible with 200 series of
detectors and 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.
7. Please refer to Detector Installation Instruction if 200 series
detector is needed.
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.
When B501 mounting base enables tamper-resistant function, special
tools must be used to disassemble addressable base. Please refer to
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

To enable this feature, Diagonal pliers can be used to twist the break
tab at dotted line toward center of base.
Figure 4
Synchronization
When addressable base send out a fire alarm, control panel can send
out a certain signal to synchronize all the addressable AV in same loop
to send out fire alarm signal.
Note: Please dispose electronic waste following national or local regulations
after being scrappedor replaced. Do not discard.
