ALARM LOOP ARMING AND DISARMING

The Signal-10 provides arming and disarming its alarm loops in the following ways:

− locally by presenting a User key to the device reader

− remotely by network controller commands for common or individual alarm loops arm-

ing/disarming

Alarm loops of all types can be armed and disarmed, except for loops of Type 6 (Auxiliary alarm loops)

and Type 12 (Programmable Auxiliary alarm loops). The conditions of these loops are continuously

monitored, a loop breaking always causing an alarm (these loops are always armed). Also, the alarm

loops with the Never Disarm attribute set cannot be disarmed.

When making attempt to arm or disarm Auxiliary alarm loops (of Types 6 or 12) or alarm loops with the

set Never Disarm parameter, the device sends the current status of these loops to a network controller.

Arming/disarming an alarm loop of Type 14 leads to arming/disarming only for those its addressable

zones which are related with the loop by means of Related Addressable Detectors parameter (see page

76). The addressable zones, which are not assigned to the loop, don’t alter their statuses during arming

or disarming Fire Threshold Addressable alarm loops.

Local Arming/Disarming

To arm and/or disarm alarm loops locally, present an electronic identifier registered in the device

memory with the respective access rights (a User key) to the device reader. Presenting the key will

simultaneously arm (disarm) all the alarm loops of this device which are associated with this key.

If the device recognizes the code of the presented identifier, it beeps and the alarms loops associated

with this identifier become armed or disarmed. If the read code is unknown to the Signal-10, the device

produces long sound tone indicating that the presented key is rejected.

If the presented key offers only privilege to arm loops, it cannot be used to disarm these alarm loops.

Such key can only arm the loops again.

If the presented key offers only privilege to disarm loops, it cannot be used to arm these alarm loops but

only to disarm the loops again.

Centralized Remote Arming/Disarming

The Signal-10 device enables a network controller to arm/disarm remotely either its individual alarm

loops and addressable zones or partitions of the Orion system operating under this network controller.

For centralized arming and/or disarming of separate alarm loops (and addressable zones of

threshold addressable initiating devices), the network controller sends commands to the Signal-10 de-

vice over the RS-485 interface line.
