Description
The Amplifier Art. 692M and Art. 692M/5 is used in Two-Wire video door entry systems,
when the modulated video signal needs to be amplified.
Adjustment
Art. 692M and Art. 692M/5 offer two output amplification levels, depending on the GAIN
dip-switch setting:
-
Position
(minus) gain is +6 dB
+
Position (plus) gain is +14 dB
When selecting the gain level, please refer to the "Video signal attenuation/gain table".
The table can be used to calculate the value of the video signal arriving from the monitor,
which should be no lower than -20 dBm.

Technical specifications

- Operating temperature +5 / +40°C
- Dimensions in mm 60 (L) x 82 (L) x 21 (H)
- IN terminal = Two Wire bus input terminal
- OUT terminal = Two Wire bus output terminal
- GAIN = (+6dB / +14dB)
- Maximum IN level with GAIN dip-switch setting on position "–" = 9 dBm
- Maximum IN level with GAIN dip-switch setting on position "+" = 1 dBm
- Maximum thru-connection current = 1,4 A
- Standby current with no video signal 24 mA
- Maximum consumption 48 mA

All Monitor
* Note: The concentrator 69MX, 69MX/5 restores le signal de la valeur +16 dBm.
Installation example:
One entrance panel, 400 m cable, five distributors 692D and one monitor connected to an extension output of the final 692D.
+16 dBm (entrance panel) -20 dB (cable) -20 dB (distributor) -2 dB (thru-connection distributors) = -26 dBm (to the monitor)
In this case it is necessary to add an amplifier Art. 692M set to 14 dB (dip-switch position + to obtain a signal of approx. -12 dBm
for the monitor).
