EDS - TECHNICAL INFORMATION
The example shows the connection among nr. 5
RK70R - RK75R and the alarm station.
Furthermore it is indicated the connection with the
modules EV570 (electronic voltmetre) and EV450
(piezoelectric buzzer) allowing.
- visualization of the signal level measure
- the sensitivity remote adjustment
- the remote indication of the detector prealarm
conditions
fig. 10
The modules EV570 (electronic voltmeter) show
the signal level and permits the sensitivity
adjustment of the detectors to which it is connected.
The module EV450 (piezoelectric buzzer) gives
an acoustical signal when one of the detectors in
prealarm condition. This module can control 5
detectors at the same time.
