tional addressable zones of the Signal-10. On the contrary to other types of alarm loop, the Signal-10

neither measure resistance values of the alarm loop with the detector included and nor estimate its sta-

tus. The Signal-10 polls all included (and related to the loops) addressable detectors or call points to

generate its generalized statuses (see Fire Threshold Addressable Alarm Loop (Type 14) section of this

Manual). This generalized status of all related addressable zones of the loop is then displayed by the

internal device sounder and the relative LED (as shown in Table 8 and Table 9) as well as initiates relay

activation in accordance with the given program and is transmitted to a network controller.

The network controller displays both generalized statuses of the addressable loops and individual sta-

tuses of each addressable zone returned by the relevant initiating device and transmitted by the Signal-

10 to the network controller.

The Armed generalized status for a loop of the Type 14 means that all its addressable zones are armed

and has responded with Norm status.

A loop of the Type 14 switches to the Fire Prealarm status after actuation of a single smoke detector.

The loop is considered to be in Fire Prealarm status until the time given by the Alarm Delay pro-

grammed for the loop has expired. This delay enables estimating all the conditions and canceling, if

required, initiating external annunciators and automated extinguishing systems.

The loop switches to the Fire Alarm status either a second detector in the loop has actuated or until the

Alarm Delay has expired. If the Alarm Delay is set as 255 s, the loop can reach the Fire Alarm status

only if a second detector in the loop has actuated. Switched to the Fire Alarm status, the loop initiates

activation of related relay(s) programmed with the executive programs 1…8, 33, 35.

If the Auto Arming After Alarm parameter is set for an alarm loop of the Type 14, the Signal-10 automat-

ically tries to arm its related addressable zones if these zones has responded with Norm status for more

than the time period equal to 15 times Alarm Delay in seconds.
