Battery Back-Up (System); Busy Lamp Field - Dss - Comdial DX-80 Installation & Maintenance Manual

New DX-80 systems are shipped with the "Cold Start/Normal" option strap in the "Cold Start" position. When a new
DX-80 system is received this strap MUST be moved to the "Normal" position to allow system operation.
Note: We recommend that the system power be restored in a timely manner since the Lithium Ion battery is
not recharged. Continued discharging of the Lithium Ion battery will render the battery inoperable for the
intended purpose. Considering normal system use and periodic loss of commercial AC power, the Lithium
Ion battery life expectancy is 5 years. When necessary, replace with a like battery.

Battery Back-Up (System)

An external UPS (Uninterruptible Power Supply) (Optional) may be installed to connect between the KSU and a
dedicated 110VAC outlet. The approximate time, in back-up hours, will be determined by size (amp/hour rating) of
UPS installed. In the event of a commercial power outage, the UPS will provide the necessary system voltage to
allow full system operation until AC power is restored or the UPS battery voltage reaches minimum voltage
thresholds and is automatically disconnected to avoid battery damage.
The UPS system battery operation time is dependent on several factors:
•
Number of Digital key telephones installed
•
System traffic load
•
Age of external batteries
•
Equipment Room Temperature
•
UPS Amp/hour rating
•
Recovery time since last AC power interruption
For further information, see Specifications and Installation sections for more details about how to calculate the power
consumption of your DX-80 system application and apply this to the UPS requirement.
Busy Lamp Field – DSS
Depending on user requirements, any Programmable Feature Button can be programmed as a BLF button to monitor
an extension's status. When an extension is off hook the programmed BLF button LED for that extension lights red.
When that extension is in Do-Not-Disturb, the LED will flash red. This same button is used as a one-button Direct
Station Selection (DSS) call button for quick transfer of calls or intercom calling.
