3.10DK8 KSU and DK16 Base Unit Relay

3.11The DK8 KSU or DK16 Base Unit Relay can be programmed for one of three options:

• BGM mute

• Night transfer

• MOH source control

These options are set in Program 77-1(LED 01 and 02). Only one option is allowed per installation. However, in the DK16, these options can be supple- mented with PIOU/PIOUS relay options. Refer to Chapter 8 for wiring/interconnecting details. Elec- trical specifications for the relay contacts are as follows:

Voltage

•24VDC maximum

Current

•1 ampere maximum

•Normally open—closed when activated

3.20DK16 Expansion Unit PIOU and PIOUS Relays

3.21The Expansion Unit via the PIOU or PIOUS provides two additional relays that control periph- eral options (see Figures 7-6, 7-7, 8-23, and 8-25).

• Door Lock Relay/BGM mute

• Night Transfer/Music-on-Hold Relay

NOTE:

The above relay options are available in con- junction with the Base Unit relay option.

3.22Each relay may be configured as normally open (make) or normally closed (BREAK). Electri- cal specifications for the relay contacts are as follows:

Voltage

• 24VDC maximum

Current

• 1 ampere maximum

CAUTION!

Do not connect relays directly to 120VAC power source.

figure the PIOU or PIOUS for the door lock control function in accordance with the following steps (refer to Figure 7-6 and 7-7):

NOTE:

Only one door lock control is available using an optional interface PCB (PIOU or PIOUS), be- cause only one interface PCB is allowed .

1)Access Program 77-1. Set LED 07 for the door lock control function.

2)Access Program 77-1. Set LED 20 to OFF for a 3-second door lock activation time, or set LED 20 to ON for a 6-second door lock activation time.

3A) Set the P10 jumper plug on the PIOU to the

MAKE or BREAK position, as required:

•MAKE—Shorts the normally open con- tacts (pins 7 and 32) when a station’s door lock button is pressed.

•BREAK—Opens the normally closed contacts (pins 7 and 32) when a station’s door lock button is pressed.

3B) Solder the W1 jumper plug on the PIOUS to the MAKE or BREAK position as required:

•MAKE— Shorts the normally open con- tacts (DET and DER) when a station’s door lock button is pressed.

•BREAK— Opens the normally closed contacts (DET and DER) when a station’s door lock button is pressed.

4)Refer to Figure 7-8 for wiring/interconnecting details. Connect the PIOU or PIOUS to the MDF as required for the door lock control function.

3.24DK8 and DK16 DDCB Door Lock Control. In addition to the door lock control provided by the PIOU or PIOUS (DK16 only), each door phone/lock control box (DDCB) installed provides one door lock control. Only two DDCBs can be installed in a system: On DK8 a DDCB can be connected to Circuit 3 (Port 02) and/or Circuit 4 (Port 03); on DK16 a DDCB can be connected to the circuit 5
