TRANSCEIVER AND I/O EXPANSION MODULE STATUS LED INDICATIONS

Power LED Indicates the presence of power to the module. It is ON when power is present and OFF when
there is no power.
Status LED When flashing rapidly, it indicates an internal error or a module type mismatch. A module type
mismatch occurs when the module address selection for two different modules (i.e. one digital
modules and one analog module are set to the same address or two pairs of modules are sharing
the same address).
RF Link LED Flashes once every two seconds when there is no RF link.
Note: At the Master transceiver, an RF Link failure will not be indicated by the master
transceiver or the connected I/O Expansion Modules until the master has lost RF Link with
all Remote transceivers. A Remote transceiver will indicate a loss of RF Link when it
cannot communicate with the master transceiver.
Flashes rapidly when signal strength is marginal (see the RSSI graph in the Servicing section of
this guide.
ON steady indicates an exceptionally strong RF link.
Most systems will flash occasionally indicating the presence of intermittent interference in the
area.
Digital OFF means that the digital input or output circuit is Open.
Input/Output ON means that the digital input or output circuit is Closed.

PULSE INPUT MODULE DIAGNOSTIC LED'S

There are 4 diagnostic LED's on the pulse input module:
Status LED: On solid when I/O is functional and flashing if there is a conflict with another module.
Backup Power LED: On solid when the backup power supply is powering the module. Off when primary
power is powering the module.
Pulse Input 1 and 2 LEDs: These lights will flicker at a varying frequency when pulses are applied to each
channel:
Frequency Range (Hz)

10 < frequency ≤ 100
