5.2.3.4  Alarm Thresholds (Device Sensitivity)

•

 

If the panel has the day - sensitivity mode option enabled, then an individual detector (heat or smoke) can be
programmed to have alternate pre-alarm and alarm values.

•

 

For example, assume a temperature detector located on loop 1, address 26 requires: -

Time Period

Pre-alarm Level

Alarm Level

Between 06:30 and 17:45

50

62

At all other time of the day – default

settings

45

55

Table 5 - Alarm Threshold Setting

•

 

This can be achieved as follows :-

1.  Select the required device address and then press the “Change” key.

2.  Press 2 to select the “Alarm Threshold” option. (This option is only displayed for smoke and temperature

detectors). The display will then prompt the alternative thresholds to use when in day mode.

Fire      =  55    (normally 55)  OK ?

3.  Press 

No

 to reject the value shown and then enter the required numeric value. For example, enter a level

of 62.

4.  The display will then prompt the pre-alarm threshold level.

Pre-Alarm =  45    (normally 45)  OK ?

5.  Press 

No

 to reject the value shown and then enter the required numeric value. For example, enter a level

of 50.

The panel will not allow the pre-alarm threshold to be higher than the fire alarm.

If the value shown is correct, press Yes to step on and leave the value unchanged.

The values presented and entered depend on the make of signaling device. Refer to the
instructions supplied with the loop driver card for information on allowed settings.

•

 

Both thresholds have now been set and the display reverts to showing the present analogue output from the
sensor. However because alternative pre-alarm and fire alarms have been set, the display will automatically show
these whenever this device is called up in the inspect or configure modes.

L1 Z003 A026 RESEARCH ROOM 52    “

 Ion Smoke   Signal= 26  (P=50 F=62)

•

 

P=50 signifies the daytime pre-alarm is now at 50. F=62 signifies the daytime fire alarm is now at 62.

•

 

Step through and adjust any other devices as required.
