Samsung DCS Part 6
Installation March 2001

6.5 Doorphone and Door Lock Release

Using one pair twisted 0.5mm or 0.8mm jumper wire, cross-connect each doorphone interface mod-
ule (DPIM) to the DLI port of your choice (Figure 6–5). Next, connect the DPIM to the doorphone
using two pair twisted 0.5mm or 0.8mm wire.
When a customer-provided electric door lock release with power supply is installed, cross-connect
the corresponding door release contacts on the DPIM to the door lock mechanism (Figure 6–5). Use
MMC 501 to program the duration of the contact closure as required. (See the Samsung DCS Keyset
User Guide for details of door lock release operation.)
The door release contacts on the DPIM are to be used for low-voltage relay control only. The con-
tacts are rated at 24 VDC–1 amp.
WARNING: Do not attempt to connect commercial AC power to these contacts.

6.6 Serial Interface Module (RS232C)

(SIM) to the DLI port of your choice (Figure 6–6).
SIMs may also be connected to a digital keyphone daughterboard (KDb-DLI).
