SIGNAL-20P APPLICATION

− "Fire Signal" if one smoke (normally opened) detector included into

the type 1 or type 2 alarm loop has actuated

− "Fire Prealarm" if one heat (normally closed) detector included into

the type 2 or type 3 alarm loop has actuated

− "Fire Alarm" if both smoke or both heat detectors included into the

type 1 or type 3 alarm loop has actuated

− "Fire Trouble" in case of short or open failure of alarm loop

Alarm loops of type 1 and type 2 transits from “Armed” to the “Fire

Signal” status if one smoke (normally opened) detector has actuated. In

such a case the device requeries the alarm loop status, that is, resets the

actuated detector and waits for it second actuating. If within 1 min the de-

tector has actuated again the device switches the loop into the ”Fire

Prealarm” status otherwise the loop enters the “Armed” status. If the pa-

rameter “Fire Loop Requery Blocking” is set on for loop in question the de-

vice switches the loop into the ”Fire Prealarm” status at once after first de-

tector actuation.

Fire loops enter the “Fire Prealarm” status after single detector actua-

tion. The duration of “Fire Prealarm” status is determined by “Intrusion/Fire

Delay” allowing to study the situation and to avoid the automatically starting

of fire equipment in case of false detector actuation.

The “Fire Prealarm” status having been expired, the alarm loop tran-

sits the “Fire Alarm” status. In case of type 1 or 3 loops this transition can

occur before delay having been elapsed in case of the second detector in-

cluded into this loop having actuated.

If the “Intrusion/Fire Delay” value equals to 255 then type 1 or 3 loop

enters the “Fire Alarm” status only if two or more detectors have actuated

but 2 type loop keeps the “Fire Prealarm” status until the alarm has been

reset.

The “Fire Prealarm” status is indicated by the device LED lit in inter-

rupted mode with the double 0,125 s flashes.

The alarm loop transits the “Fire Alarm” status after double detector

actuating at single type 1 or 3 loop of after “Fire Prealarm” status finishing.

The loop transiting to the “Fire Alarm” status, the relays are controlled in

accordance with the 1…8, 33 and 35 programs.

If “Auto Rearming when Fire/Alarm” loop parameter is set on then this

loop is automatically armed and transits from “Fire Alarm” to the “Arm De-

lay” status after its resistance has been within normal range for 15-fold

“Fire/Alarm Delay” sec.

The loop enters from “Armed” to “Fire Trouble” status in case of open

or short loop failures. After loop recovering and its resistance having been

within normal range for 3 s the loop is automatically armed and enters the

“Armed” status.
