Fire Signal There is an addressable zone with Test status and there are no

zones with Isolated, Trouble, or Fire Prealarm, or Fire Alarm

statuses

Arming Failed At the moment of arming, one of the addressable zones of the

loop has a not Norm status, no other zones having more priority

statuses (said above)

Arming Delay The transient status when after an attempt to arm an addressa-

ble zone the response from the addressable detector is waiting

for, and there are no zones with more priority statuses (said

above)

Dusty Sensor,

Service Required

There is an addressable zone with the Dusty status, all other

zones being in Norm

Disarmed There is a disarmed addressable zone within the loop, all other

zones of the loop being armed

Armed All addressable zones are in norm and armed

If a Fire condition has been detected for an addressable zone of a fire threshold addressable alarm

loop, this loop switches to the Fire Prealarm status. If Fire conditions have been detected for two differ-

ent addressable zones of a loop, the loop switches to the Fire Alarm status. The loop also can switch

from the Fire Prealarm to Fire Alarm status after the programmed Alarm Delay having expired. If the

Alarm Delay is set to zero for this loop, the loop switches to the Fire Alarm status after a single detector

having actuated. If the Alarm Delay is set to 255 (infinite delay), the loop can switch to the Fire Alarm

status only after two detectors having actuated.

If the Signal-10 has no response from an addressable detector within 10 s, the Isolated status is as-

signed to its addressable zone. In such a case the function of breaking the loop to remove the detector

from its mounting base can be avoided and all other detectors in the loop keep their operability. No ter-

mination resistor is included into a fire threshold addressable alarm loop. The loop can be of any topol-

ogy such as a bus, a ring, a star, or any hybrid topology.

While programming the Signal-10, it is possible to specify in advance the addresses of those detectors

which will be included into this threshold addressable alarm loop. It is implemented by the Related Ad-

dressable Devices parameter setting. If the matching an addressable zone to a particular alarm loop is

missed, then this zone is not considered when a generalized status of the alarm loop is formed and is

not affected by arming/disarming commands while the loop is armed/disarmed.
