Isolating ACF Outputs

The Ancillary Control Facility (ACF) consists of relay outputs which can be used to control

equipment which is not part of the 4100ES-S1 fire alarm system, such as shutting down air

conditioning or returning lifts to a certain floor.

During maintenance or testing, these outputs can be isolated, to prevent unwanted annoyance

to the building occupants.

Press the ACF ISOLATE key once. The ACF ISOLATE indicator will light, and the Isolate

indicator above the Isolate Ack key will flash. The LCD will display a message:

ACF ISOLATE

PRESS <ACK> key to acknowledsge

Press the Isolate Ack key to acknowledge that the ACF is isolated.

Note that isolation takes effect immediately from pressing the ACF ISOLATE key, not from

when the Isolate Ack key is pressed.

Press the ACF ISOLATE key once. The ACF ISOLATE indicator goes out.

Note: If there are any alarm conditions still active, the ACF outputs will operate as

programmed, e.g., shutdown equipment.
