Ringer Status LEDs
LED Condition
Normal operation: No alarms, inputs and outputs are in their normal range,
communicating with the system controller.
Note: In a redundant system, one ringer is in “Normal Operation” and the second
unit is in “Standby (on-line spare)”, see below.
Unpowered: No input or output voltage present.
; Remove and reinsert ringer.
; Check input voltage with a voltmeter, if input voltage is present, replace
ringer.
; Check output bus voltage with a voltmeter, if output bus voltage is present,
replace ringer.
Startup: The power unit initializing, but has not started delivering power.
; Wait for initialization to complete.
Lamp Test: The controller has initiated a Lamp Test operation
Standby (on-line spare): The ringer is okay and has input, but is an on-line
spare and is not delivering power. The unit will switch to “normal operation” if
the other ringer fails.
Standby (remote): The ringer is okay and has input, but has been placed in
Standby by the controller and is not delivering power.
External Fault:
• Ring Return not terminated
• Output limited – excessive output load
• Output limited – excessive temperature
Internal Fault:
• Thermal shutdown
• Ringer failure
Communication Fail: Blinks to indicate the ringer is not communicating with a
system controller.
; Remove and reinsert ringer. If fault remains and other units are
communicating correctly, replace ringer.
