10 Ringer Chassis and Ringers

Ringer Chassis

Overview
Ringer Chassis provide
• One ringing output – 100VA maximum
• Support for one (non-redundant) or two Ringers (1 + 1 redundant)
• Fans – Ringer powered, controlled, and monitored
• Ringing output connector
• Ringing type selection (Tip) Jumper J12
Redundant Configuration
1 + 1 redundant (duplex) operation
Two ringers are installed in a Ringer Chassis
•
• Ringing output from that Ringer Chassis is powered by the primary ringer (the one on the right)
• Should the primary ringer be removed or fail
• Ringing output will be provided by the spare ringer (the one on the left)
• An alarm will be sent and displayed by the Controller.
Non-Redundant Configuration
Non-redundant (simplex) operation
• One ringer is installed in a Ringer Chassis
• Ringing output from that Ringer Chassis is powered by that ringer
Should that ringer be removed or fail, ringing output will not provide ringing, and an alarm will be sent and displayed by
the Controller.

Ringer

Overview
Warning: The Ring signal shall be considered hazardous and shall be spaced from other circuits by
0.055 in. (1.4 mm).
Ringers convert dc to ringing power. QS820A Ringers convert -48V
with configurable ac voltage, ac frequency, and dc offset. See Ringer Specifications for details.
Output Isolation
Ringers have output relays that isolate their ringing output from the Ringer Chassis ringing output in
the event of standby operation, ringer failure, and output over-load. This facilitates 1
+ 1 redundant operation and the determination of external vs. internal faults.
Autonomous Operation
CPS6000 Controllers provide Ringer settings capability and status and alarms communications. QS820
Ringers operate without CPS6000 Controller.
When Ringers are not communicating with a Controller they
