SIGNAL-20P DESIGN AND OPERATING PRINCIPLES

Im = 3 mA for loops of 1, 4, 6, 7, 11 and 12 types

Im = 1,2 mA for loops of 2 type

I is the current consumed by detector in operating mode

If the type 1 loop is in use (that is fire smoke loop with double actua-

tion recognition) then detectors have to keep their operability when the

voltage has dropped to 12 V.

4.2 Relays

The device’s relays can be controlled by one of the following ways:

- Local control in accordance with the assigned executive programs

depending on the connected alarm loop status

- Centralized control by means of commands sent by net controller

4.2.1 Relay local control

To control the N-th relay depending on connected alarm loop status:

- Set the “Relay N Control” loop parameters on to assign the relay

with the corresponding loops

- Give the “Relay N Control Delay” loop parameters

- Give the “Relay Control Program” relay parameter

- Give the “Relay Control Time” relay parameter

The “Relay Control Program” parameter defines the relay behavior

depending on the related loop statuses. All available executive programs

are represented in Table 5.

The “Relay Control Time” parameter gives the time period of switch-

ing relay on (off) required by executive programs with the limited duration.

Except the programs (see Table 5) №№ 9 (LAMP), 10 (Alarm output

1), 13 (Fire output), 14 (Output FAULT), 15 (Fire LAMP), 16 (Alarm output

2) all other programs support the delayed relay turning on/off for time inter-

val given by “Relay … Control Delay” parameter for the corresponding

loop. So different alarm loops associated with the same relay can be given

by different starting delays.

For executive programs (see Table 5) from 1 to 8 (general purpose

programs), 11 (ASPT), 12 (SIREN), 33 (ASPT-1), 34 (ASPT-A), 35 (ASPT-

A1) the relay assigned auxiliary loop (type 6) breaking blocks up the relay

switching on. If auxiliary loop has been recovered but the switching on con-

dition depending on the other loops are retained then for the programs 1, 2,

5, 6, 12 and 33 the relay switching on will be resumed, but for the programs

3, 4, 7, 8, 34 and 35 the switching will not be on. Thus, the auxiliary loop

breaking holds the time unlimited general purpose programs along with

programs 11 and 33 and cancels time restricted programs along with pro-

grams 12, 34 and 35.
