ARAMETER

...................Option 5 (Sensitivity Boost).

ETTINGS

........................Five selections - 5.00 to 5.04.

ETTING

ISPLAYED

......The word ON or OFF will be displayed.

EGMENT

ISPLAY

......The number of this option.

EFAULT

ETTING

..........5.00 (OFF) for all loop inputs.

XAMPLE

........................Option 5.04 is turned ON for loop input 1

OTES

.............................This option is a loop input specific setting. Changing it for one

loop input changes it for that loop input only.

The maximum sensitivity level obtainable with or without sensitivity boost is level 10. If

the setting of either sensitivity or sensitivity boost is such that
the resultant sensitivity level is greater than 10 (e.g. Sensitivity
Level 7, Sensitivity Boost setting of 5.4), the audible detect
signal (buzzer) will sound to provide an indication that the
combination being selected is invalid. (See Section 2.2 -
Sensitivity for more details.)

ARAMETER

...................Option 6 (Audible Detect).

ETTINGS

........................ON or OFF.

ETTING

ISPLAYED

......The word ON or OFF will be displayed.

EGMENT

ISPLAY

......The number of this option.

EFAULT

ETTING

..........OFF for all loop inputs.

XAMPLE

........................Option 6 is turned ON for loop input 1.

OTES

.............................This option is mutually exclusive with the same option in any

other loop input. Turning it on for one loop input turns it off
for all other loop inputs. This option will automatically turn off
after 15 minutes.

ARAMETER

...................Loop Check Timer setting.

ETTINGS

........................256 selections - 000 to 255 minutes in 1 minute steps.

ETTING

ISPLAYED

......7-segment display will show currently selected setting.

SEGMENT

ISPLAY

......Currently selected time in minutes.

EFAULT

ETTING

..........Five minutes (005) for all loop inputs.

XAMPLE

........................The Loop Check Timer for Loop 1 is set for 25 minutes.

OTES

.............................This option is a loop input specific setting. Changing it for one

loop input changes it for that loop input only.

ARAMETER

........................Detector ID setting.

ETTINGS

.............................256 selections - 000 to 255.

ETTING

ISPLAYED

...........7-segment display will show currently

selected setting.

SEGMENT

ISPLAY

...........Current Detector ID setting. The display

will toggle between the two screens with
a 50% duty cycle.

EFAULT

ETTING

...............255.

XAMPLE

.............................Detector ID is set as 158.

OTES

..................................When set to Detector ID number 255, the

detector is considered uninitialized.

ARAMETER

...................Option 7 (Synch Feature).

ETTINGS

........................Three selections - 7.00 to 7.02.

ETTING

ISPLAYED

......The word ON or OFF will be displayed.

SEGMENT

ISPLAY

......The number of this option.

EFAULT

ETTING

..........7.00 (OFF) for all loop inputs.

XAMPLE

........................Option 7 is turned OFF.

OTES

.............................This option is a detector-wide setting. Setting Option 7 to 7.01

activates Series Synch (SYS), setting Option 7 to 7.02 activates
Parallel Synch (SYP).

OPTION

LOOP FAIL

SCANNING

OPTION
