Signal-10 Operation Principles

41 www.bolid.com

Fire Prealarm A heat (normally closed) detector has actuated within a fire alarm loop of

the Type 2 or 3

Fire Alarm Two smoke or heat detectors have actuated together within a fire alarm

loop of the Type 1 or 3 relatively

Trouble Short or open circuit failure has occurred within the alarm loop

Alarm loops of the Types 1 and 2 switches from the Armed status to the Fire Signal status if a smoke

(normally open) detector has actuated within the loop. In such a case the Signal-10 repeatedly queries

loop conditions. If the Fire Loop Requery Prohibition parameter is set of for this loop, the loop switches

to the Fire Prealarm status immediately.

Fire alarm loops switch to the Fire Prealarm status either after a single heat detector actuation or after a

confirmed smoke detector actuation. The duration of being in the Fire Prealarm status for each alarm

loop is defined by the programmed Alarm Delay value. This delay enables analyzing the circumstances

and canceling an alarm before generation any signal to start annunciator or automatic fire fighting

equipment.

After the termination of the Fire Prealarm status the loop switches to the Fire Alarm status. Alarm loops

of the Types 1 and 3 can switch from the Fire Prealarm status to the Fire Alarm status before expiration

the delay if a second detector has actuated.

If the programmed Alarm Delay is equal to 255, loops of the Type of 1, 3, and 14 switch to the Fire

Alarm status only upon two or more detector actuations, while a loop of the Type 2 keeps Fire Prealarm

status until the alarm is canceled.

An alarm loop switches from the operation mode to the Fire Alarm status, if either two detectors have

actuated for the loops of the Type 1, 3, or 14 or Fire Prealarm status has been terminated. Also, while

switching a loop to the Fire Alarm status, the relay related with this loop and programmed with one of

executive programs 1…8, 33, or 35 is activated.

If the Auto Arming After Alarm parameter is set on for a loop, the loop is automatically armed and

switched from the Fire Alarm status to the Arming Delay status when its resistance has been in normal

range for more than 15 times the Alarm Delay value in seconds.

An alarm loop switches from Armed status to the Trouble status if an open or short failure has been

occurred within the loop. If the loop is restored and its resistance has been within the normal range for

more than 3 s, the loop is automatically armed.

Addressable Fire Alarm Systems

The Signal-10 can operate as a polling addressable fire alarm device if at least one of its alarm loops is

configured with the Type 14 (Fire Threshold Addressable). Bolid manufactured DIP-34PA smoke detec-

tors, or S2000-IP-PA detectors, or IPR513-3PA call points must be included to an alarm loop of the

Type 14 (up to 10 initiating devices to each loop). These initiating devices are considered to be addi-
