SP.Ac

 - setpoint access only. This blocks access to any functions except the

alarm setpoint functions unless the remote input pins are short circuited or
entry is made via 

CAL

 mode.

No.Ac

 - no access. This blocks access to all functions unless the remote input 

pins are short circuited or entry is made via 

CAL

 mode.

duLL

 - display brightness control. The remote input can be used to change

the display brightness. When this mode is selected the display brightness can
be switched, via the remote input, between the brightness level set at the

brgt

 function and the brightness level set at the 

duLL

 function.

A.cIr

 - acknowledge or reset alarm, used when 

A

x 

Ltch

 is set to 

on

 i.e.

when using latching alarm relays. The remote input can be used to
acknowledge an alarm condition or reset the alarm. If the remote input is
activated when there is still an alarm condition then the alarm will be
acknowledged and the relay will automatically reset when the input moves out
of alarm condition. If the remote input is activated when the input has been in
an alarm condition but is no longer in alarm condition then the relay will
immediately reset. See 

A

ACCS

 has four possible settings

namely 

OFF

EASY,

 

NONE

 and 

ALL

. If set to 

OFF

 the mode function has no

effect on alarm relay operation. If set to 

EASY

 the easy alarm access mode

will be activated, see details at the beginning of this chapter preceding the

A1Lo

 function. If set to 

NONE

 there will be no access to any functions via

FUNC

 mode, entry via 

CAL

 mode must be made to gain access to alarm and

calibration functions. If set to

 then access to all functions, including

calibration functions, can be gained via 

FUNC

 mode.

Setpoint access - seen only if more than 1 relay fitted.
Sets the access to the alarm relay set points. The following choices are
available:

A1

 - allows setpoint access to alarm 1 only.

A1-2

 - allows access to alarms 1 and 2.

A1-3

 - allows access to alarms 1,2 and 3.

A1-4

 - allows access to alarms 1, 2, 3 and 4

The remote input function (

R.INP

) must be set to 

SP.AC

 for this function to

operate. Note: Only the setpoints which have been given a value will be
accessible e.g. if 

A1Hi

 is set to 

OFF

 then there will be no access to the

A1Hi

 function when 

SPAC

 is used.
