INTRUSION&FIRE ALARM ADDRESSABLE 20-LOOP CONTROL DEVICE

this loop enters the “Fire Prealarm” status. If the second actuating has not

occurred within 55 seconds the alarm loop returns to the “Armed” status.

From the “Fire Prealarm” mode the device can transit to the “Fire alarm”

mode if the second detector has been actuated or “Intrusion/Fire Delay”

has expired at this loop. If “Intrusion/Fire Delay” was given as 0 then the

transition from “Fire prealarm” to “Fire alarm” mode would happen instantly.

If “Intrusion/Fire Delay” was given as maximum value 255 then the transi-

tion from “Fire prealarm” to “Fire alarm” would be able only after actuating

of the second detector at the same loop.

The type 1 alarm loop resolving time is determined in accordance

with the requirements of the section 4.1.2.

The coupling between the alarm loop resistances and statuses can

be shown in Table 3.

The diagram of connection the fire smoke (normally opened) detec-

tors to the type 1 alarm loop is contained into the Appendix E.

The type 2 is the fire combined alarm loop.

The fire smoke (normally opened) and heat (normally closed) detec-

tors are included into the alarm loop. The alarm loop statuses can be:

“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.

“Fire prealarm” – the heat detector actuation or second smoke detec-

tor actuation has been fixed.

“Fire alarm” - after detector actuation the “Intrusion/Fire Delay” has

expired.

“Loop trbl short” – the alarm loop resistance is less than 100 Ohm.

“Loop trbl open” - the alarm loop resistance is more than 16 KOhm.

“Arm Failed” – the alarm loop was broken when arming.

When heat detector has actuated the device enters the “Fire

Prealarm” mode. When smoke detector has actuated the device generates

“Fire Signal” message and repeatedly requests the alarm loop status (see

type 1). If within 55 seconds after de-energizing the detector connected to

this loop repeats actuating the device enter the “Fire Prealarm” mode.

From the “Fire Prealarm” mode the device can transit to the “Fire

alarm” mode if “Intrusion/Fire Delay” has expired. If “Intrusion/Fire Delay”

was given as 0 then the transition from “Fire prealarm” to “Fire alarm” mode

would happen instantly. If “Intrusion/Fire Delay” was given as maximum

value 255 then the transition from “Fire prealarm” to “Fire alarm” would be

impossible.
