AUXILIARY ALARMS

The Signal-10 device enables monitoring and transmitting to an Orion network controller the conditions

of various technological circuits being not directly related to fire and intrusion alarms. Such the circuits

involve contacts of devices blocking automated fire–fighting systems, mass sensors, press sensors,

flow sensors, throttle valves, liquid level controls and so on.

For these purposes the loops of Type 6 (Auxiliary) and Type 12 (Programmable Auxiliary) are used.

Loops of these types can be neither armed nor disarmed: they are always monitored by the device,

breaking of these loops (that is, Auxiliary Alarms) being always indicated by the Signal-10 device and

transmitted to the network controller.

Auxiliary loops of the Type 6 are considered to be in one of two available statuses, namely the Auxil-

iary Zone Alarm and Auxiliary Zone Restored ones. In such a case, if an alarm loop of the Type 6 is

matched with any relay output of the Signal-10 (the relevant Relay … Control parameter is on for this

loop) breaking of the loop will block activation of the relay controlled in accordance with a given pro-

gram.

This type of alarm loops is suitable, for example, to block automatic start of a fire-fighting system in the

case when a door to the premises is opened.

An alarm loop of the Type 6 switches from the Auxiliary Zone Restored status to the Auxiliary Zone

Alarm status if the alarm loop has held broken for at least 300 ms.

Recovering of the broken alarm loop of the Type 6 (that is, switching from the Auxiliary Zone Alarm to

the Auxiliary Zone Restored status) is implemented automatically if the resistance of this loop has come

to the normal range and is held normal for the time interval equal to Arming Delay parameter pro-

grammed for this loop.

Breaking of an alarm loop of the Type 6 causes blocking the relay related with this loop and controlled

by the following programs:

− #1…#8 (general purpose programs)

− #11 (ASPT)

− #12 (Siren)

− #33 (ASPT-1)

− #34 (ASPT-A)

− #35 (ASPT-A1)

Blocking of a relay upon breaking of a loop of the Type 6 implies that:

− The relay is not activated if the loop has already been broken

− The relay is returned to an initial condition of the given executive program if the relay was

being controlled when the loop has been broken.
