Switch Inputs; External Switch Function Settings - Ametek 90B Series Installation And Configuration Manual

Switch Inputs

This screen is used to set up the optional External Switch Inputs (Option SW).
The External Switch Inputs provide several inhibit functions that are commonly
used when the system is left in an 'in-manned state' and there is no need to flash
alarms or sound horns. There are other configurations available on this page to
configure the Test Pushbutton Operation.

External Switch Function Settings

LED Lamp Inhibit
If selected, whenever the switch is closed, all LED Lamps in the system will be
disabled. If the operational sequence chosen latches the alarm (A, M, etc.), any
alarms that occurred while the inhibit switch was enabled as well as any current
alarms will be displayed as soon as the switch returns to the 'off' position.
Horn Inhibit
If selected, whenever the switch is closed, all Horns in the system will be
disabled. (This includes the internal horn and external horns connected to the
CSM Relay outputs.) If the operational sequence chosen latches the alarm (A, M,
etc.), any alarms that occurred while the inhibit switch was enabled as well as
any current alarms will be sounded as soon as the switch returns to the 'off'
position.
Repeat Relay Inhibit
If selected, whenever the switch is closed, all Repeat Relays in the system will be
disabled. If the operational sequence chosen latches the alarm (A, M, etc.), any
alarms that occurred while the inhibit switch was enabled as well as any current
alarms will operate as soon as the switch returns to the 'off' position.
