RED
Steady when DC supply is connected, and data is being
received from the host controller.
Flashing When the DC supply is connected and the data
connection to the host controller is not operating.
Status 1-8
RED
Lit when the corresponding channel is active.
ID Switch - The rotary ID switch is used to select the ‘Identification’ of the 2548 expansion
module as the host controller is capable of giving instructions to a number of 2548 expansion
modules at the same time (consult relevant modules instructions for further details on number
of supported expansion units).
The switch (located at the rear of the module) should be operated using a small screwdriver and
set to match the required ID.
NOTE 1: The ID MUST be a unique number, different from the ID of any other 2548 module
connected to the host controller.
If two or more 2548 controllers are required to ‘mimic’ each other then they should be configured
with different IDs, and both configured the same in the host controller.
NOTE 2: The selection of the ID of
other types
of expansion modules WILL NOT interfere/clash
with the ID of the 2548. For instance, if the 2548 is set to ID4, it is acceptable to have a
different
type
of expansion module (for instance 2130) set to ID4 also.
Sounder - The 2548 LED expansion module has an integral sounder, activated upon a signal from
the ‘host controller’. The controller will activate the sounder when an alarm becomes active and
silence the sounder when an alarm mute button (local or remote) is pressed.
Push Button - Pressing the button will signal to the host controller that the button is pressed.
The controller will respond by lighting all LEDs on the 2548 module (lamp test) and silencing
the sounder (alarm mute). If configured to do so, the host controller will also perform a lamp
test and alarm mute function.
