9.0 Indicators, Controls, & Operation

9.3 Circuit Status Indicators
There are two LEDs for each Input Circuit and one LED for each Indicating and Relay Circuit. For the 4 Input
Circuits, they are labelled Input 1,2, 3, and 4. For the first four Indicating Circuits on the Main Board, these are
labelled Output 1, 2, 3 and 4. For all other Adder Modules these are arranged in columns of eight indicators
numbered from 5 to 12 - top to bottom and 13 to 20. Each Circuit Status LED for the input circuits is red and is on
steadily to indicate active input. Each Circuit Trouble LED (for both input and indicating) is Amber and in general
flashes at the Trouble Flash Rate when active.
Input Circuit Status Indicators
This operation applies to Input Circuits configured as alarm. The Circuit Trouble Indicator flashes at the Trouble
Rate to indicate circuit trouble (open circuit) or if the circuit is Disconnected. The Trouble LED is always turned off
when the Input Circuit is active. The Circuit Status Indicator is activated steady red when the Input Circuit is active.
This Circuit Status Indicator will illuminate at the Fast Flash rate while an active circuit is reconnected (after being
Disconnected).
Output Circuit Indicators
This operation applies to Output Circuits of any type. The Circuit Trouble Indicator flashes amber at the Trouble Rate
to indicate short-circuit or open-circuit trouble, or if the circuit is Disconnected.
Relay Circuit Indicators
Relay Circuit Trouble Indicators flash amber at the Trouble Rate while the circuit is Disconnected.
9.4 Circuit (Zone) Disconnect Switches
Circuit (Zone) Disconnect Switches are provided for all Indicating and Relay Circuits on the BPS-1100. For the first
four Indicating Circuits on the Main Board, the Disconnect Switches consist of a bank of DIP Switches. For DIP
Switches, numbers 1 to 8 correspond to the Circuits indicated in the Indicator column from top to bottom. Changing
a Circuit Disconnect Switch to the ON position bypasses the associated Circuit and turns on its Trouble Indicator,
also activating Common Trouble. While a Circuit is Disconnected, all changes in status (Troubles) on that Circuit are
ignored. Disconnected Indicating Circuits are not activated by the Input Circuits. Disconnecting an active Indicating
Circuit immediately deactivates the Circuit. Note: indicating and output terms are used
These Disconnect Switches are also used during Configuration Mode as described in those sections.
Note:
Indicating and output terms are used interchangeably.
Note:
Inputs must be steady for BPS-1100 outputs to be active. The BPS-1100 will not respond to
pulsing
input contacts.
Note:
indicating and output terms are used interchangeably.
