Electronic cassette EC-2502 can control electro-catch (by default setting). It is also a possibility to
control electromagnetic lock (or reverse
electro-catch). The selection of control method enables jumper ZT1.If electromagnetic lock is used
jumper should be put on joint J3 and operation frequency (parameter FrY) should be set on 0! (see
figure 2).In case electro-catch is used jumper should be removed from joint J3.
Figure 2: Selection of electro-catch or electromagnetic lock.
4. ADJUSTMENT
Elements of entry phone system are preliminarily adjusted and position of internal
potentiometers should not be changed without necessity.
Electronic cassette EC-2502 has the following adjustment elements (see dwg. 3):
P1 - volume control in external panel loudspeaker
P2 - volume control in uniphone loudspeaker (amplification of panel microphone)
P3 - line balance responsible for the lack of acoustic interference
Figure 3: Control elements in electronic cassette
Additional there are potentiometers for control acoustic track:
P4 - amplification of microphone track in external panel (potentiometer in external panel)
P1 - amplification of microphone track in uniphone (potentiometer is in uniphone)
A detailed description of the regulation of electronic cassette EC-2502 is in the installation, service
and programming instruction of digital entry phone system CD-2502.
