INTRUSION&FIRE ALARM ADDRESSABLE 20-LOOP CONTROL DEVICE
18
“Armed” – the alarm loop is monitored and the resistance is in normal
range.
“Disarmed” - the alarm loop is not monitored.
“Arm Delay” – the arming delay has not yet been elapsed.
“Entry Alarm” – the loop breaking has been fixed.
“Intrusion Alarm” – after having entered “Entry Alarm” status the “In-
trusion/Fire Delay” period has expired.
“Arm Failed” – the alarm loop was broken when arming.
The performance and parameters of entering alarm loop are identical
to those of type 4 burglary alarm loop, except that breaking of armed loop
switches it at first to the “Entry Alarm”. If within the “Intrusion/Fire Delay”
period no arming or disarming of the alarm loop has occurred the loop
would enter to the “Intrusion Alarm” status.
While the alarm loop is in the “Entry Alarm” status the relay switching
by means of executive general purpose programs 1 – 8 or SIREN program
12 does not perform.
This type alarm loop resolving time is 70 ms or 300 ms depending on
“300 ms Integration” parameter value.
The compatibility of loop resistance and the corresponding status can
be shown at the Table 3.
The diagram of connection burglary detectors to the type 7 alarm
loop is identical to type 4 loop connection diagram and is contained into the
Appendix E.
The type 11 is the alarming loop
.
The alarming loop includes normally opened and normally closed
alarm devices (call points, footboards and so on).
The alarm loop statuses can be:
“Armed” – the alarm loop is monitored and its resistance is in normal
range.
“Disarmed” - the alarm loop is not monitored.
“Arm Delay” – the arming delay has not yet been elapsed.
“Silent Alarm” – attack, the alarm loop breaking has been detected.
“Arm Failed” – the alarm loop was broken when arming.
The operating and parameter settings of the alarming loop are similar
to those of type 4 loop except that breaking of the armed alarming loop
leads it to the “Silent alarm” status.
This status impacts only the relay controlled by means of 10 program
(Alarm output 1) or 16 program (Alarm output 2) with relay being opened.
The external audible and visible alarms controlled by LAMP (9) and SIREN
(12) programs don’t change their statuses.
