LOOP STATUS LIGHT AND SOUND INDICATION

While operating, the Signal-10 device indicates current statuses of all its connected alarm loops by

means of its 1 − 10 LEDs and built-in sounder. For loops of the Type 12 light indication depends on the

type of programmed events.

Sound signaling is provided only for fire and intrusion alarm loops (not for auxiliary loops). The sounder

behavior depends on the most dangerous event which is detected by all the device alarm loops.

Table 8 shows the behavior of the 1 – 10 LEDs of the device indicating the current statuses of the rela-

tive alarm loops, while Table 9 (see the page 52) describes the characteristics of sound signals which

are output by the device for some alarm loop statuses.

There are two ways the Signal-10 provides light indication for statuses of fire alarm loops (of Types 1,

2, 3, 14), namely its own way and the way which is required by EN-54 standards. The way being in use

depends on the current setting of the device system parameter EN-54 (see the Signal-10 System Set-

tings section of this Manual).

If the EN54 is disabled, the main statuses of fire alarm loops (that is, Armed, Disarmed, Arming Failed

and so on) are indicated by the device LEDs similarly to those of intrusion alarm loops.

If the EN54 parameter is set on (enabled) the statuses of fire alarm loops are displayed as follows:

Armed The LED is off

Disarmed The LED is lit steady with yellow

Arming Failed The LED flashes with yellow

Fire Signal

Fire Prealarm

Fire Alarm

The LED flashes with red

For loops of the Type 14 a generalized status is indicated (see Fire Threshold Addressable Alarm Loop

(Type 14) Section of this Manual) by the device LEDs.

For loops of the Type 12 light indication depends on the type of programmed events.

Sound signaling is provided only for fire and intrusion alarm loops (not for auxiliary loops). The sounder

behavior depends on the most dangerous event which is detected by all the device alarm loops.
