Balanced Tamper-line connection

Omnia8 and Omnia4 have a balanced 24h Tamper line for the tamper mi-

croswitches of the Alarm system devices. Connect as follows:

1. Connect the tamper microswitches of all the security system devices in se-

ries.

2. Connect one end of the series to terminal 17[AS] and the other to terminal

18[ ]: connect the balance resistor to the last device.

The Tamper line does not identify the tampered device. If required, use the

double balanced mode for sensor connection, and 24h zones for tamper

identification on other devices.

Connection of auxiliary outputs

The Omnia8 and Omnia4 have 2 programmable auxiliary open-collectors:

23[O1], 24[O2]. The standby status of the output can be programmed, and

the activating signals can be selected from the following: ARMED, DIS-

ARMED, TROUBLE, ALARM MEMORY, EXIT TIME, ENTRY TIME,

CHIME, ARMING DELAY, FIRE GND, TELEPHONE LINE TROUBLE (re-

fer to "Output Programming").

A 100 mA max. current can circulate on terminals 23[O1] and 24[O2] for

the activation of other devices.

Several applications are dealt with in the "Auxiliary control of sensors"

and "Fire sensors" paragraphs.

Below are two of the many auxiliary output applications:

Ø Arming delay signalled on Buzzer: connect an auto-oscillating buzzer to

a power supply terminal (e.g. 22[+B]) and to the Normally Open auxiliary

output 23[O1] ----programmed for Entry Time signalling.
