DPH16 - Doorphone connection

Connecting doorphone can be executed via appropriate cables connected to connecting terminal located on doorphone PCB. Connecting terminal is visible and accessible afer unscrewing front panel, this operation is described in chapter 2.2 DPH - Opening doorphone casing.

Warning! Before connecting cables to connecting terminal, cables should be bring into the casing via hole located on casing backside.

Connections located in connection terminal, usetd to doorphone installation are presented in following table:

	earthing (for proper operation of doorphone over-voltage protection)
LA	PBX subscriber line (polarity is not important)
LA
EZ	electrolock, 12V DC, max 0.7A
EZ
STA	isolated normaly open relay connection used to control additional device - allowable voltage is equal to max 24V AC STA Max 0.7A
STA
AC	power supply connections 14 - 35VDC or 12 - 25VAC
AC
COD	opening door sensor - disconnection from GND decrease EZ relay operation time
POD	opening door button (relative to GND)
GND	ground for POD, COD signals

Connection scheme of doorphone DPH is presented on following figure.

DPH doorphone supply can be realized using AC or DC. Power supply device should be selected according user needs. Due to wide possibilities, Slican company doesn't offerany power supply device together with DPH doorphone, it remain to user decision. In Slican offer - as a separate position in price list - there is AC transformer TRS10-V18-N, with nominal voltage equal to 18V, this transformer fulfil supply requirements of DPH doorphone. Below is presented mentioned above transformer:
