Base Sounders
Introduction
NOTE: This section is not currently applicable to Hochiki America Device users.
Most Hochiki ESP addressable devices have addresses that are set in the range 1 to 127.
Base Sounders are different in that their address can be in the range 1 to 254, or not set at
all.
For the purposes of the True Loop Emulator, Base Sounders that have addresses in the
range 1 to 127 are defined as a different device type called Wall Sounders and are treated
as any other device.
Base Sounders usually have a sensor connected to them. If their address has not been set,
they cannot be used until one is connected.
The Loop Display only has address positions for address numbers 1 to 127. When
addresses in the range 128 to 254 are needed, the top third of the address position that is
127 less is used. Base Sounders are the only devices that can co-exist with another device
at an address position in the emulator. If there is both an Optical Smoke sensor and a Base
Sounder at address position 1, for instance, then the smoke sensor has address 1 and the
base sounder has address 128 or 'Not Set'
if it has not yet been set.
Two different forms of Base Sounder are implemented in the True Loop Emulator. The Pre-
addressed Base Sounder corresponds to a Base Sounder that has already had address set
in the range 128 to 254. The Base Sounder corresponds to a device that has not yet had its
address set; this is the device type that would more commonly used, as it is how the device
leaves the factory.
All of these devices are grouped within one Device Family and are available from the drop
down list accessed via the arrow to the side of the Base button.
Adding Base Sounders
This chapter assumes that the Interface is not yet connected to the computer, so ensure that
the serial cable is disconnected at this stage.
If necessary, use the New button to clear any existing configuration data.
Click on the Base device button (not the Pre-addressed Base Sounder or the Wall Sounder).
Use this to click on address position 1.
