6.1 External Page Relays
Two external dry contact relays are available when a PGD(2)-U10 ADP is
installed which can be used to activate ancillary devices (i.e. door unlock
devices). The CD-CP00 also provides one relay. The CD-CP00 relay is
defined as a general purpose relay in programming (Program 10-21-01 = 3).
The CD-CP00 relay 0 is assigned to the door box extension port in
Program10-05-01. When the relay on the PGD(2)-U10 ADP is used, there is
no need to assign the relay to the Door Box – simply connect the relay as
detailed in the steps below for the Door Box used. The relays on the PGD(2)-
U10 ADPs are numbered 5-8. Each Door Box/external page circuit provides a
dry relay contact.
Program Note: Program 10-21-01 sets the relay switch on the CD-CP00. If
set to 2 (External Speaker), service code 703+1 pages and the relay closes.
The relay reopens upon hang up. If set to 3 (General Purpose Relay), service
code 880+0 toggles the relay open or closed.
Š The service codes indicated are the default codes. Refer to Program
11-12-20 and 11-12-50 to redefine these codes as needed.
The PGD(2)-U10 ADP provides amplifiers for each
page output port (for a maximum of +8 dBM, 600
ohms at 1KHz). No additional page amplification is
provided by the PGD(2)-U10 ADP but, if required,
an external page amplifier can be used for additional
amplification.
The page output of the CD-CP00 does not provide
amplification (for a maximum output of -3 dBm, 600
ohms at 1KHz). If the paging volume is not
satisfactory using the CN8 or CN9 connector on the
CD-CP00, the PGD(2)-U10 ADP should be used
instead.
