FAQ (Frequently Asked Questions)
The answers to most of the following questions are available elsewhere in the handbook, but have been summarised here
for convenience.
Q :
What are the remote connection details for these units ?
A :
The HY-02 is equipped with a 5 way IP40 socket (678 series) which is assigned as follows :
Pin 1 :
Lamp Hybrid Unit 1
Pin 2 :
Divert Switch (Line Connect), Hybrid Unit 1
Pin 3 :
Common
Pin 4 :
Lamp Hybrid Unit 2
Pin 5 :
Divert Switch (Line Connect), Hybrid Unit 2
The mating connector (plug) for this remote is supplied with your HY-02 unit. Check your packaging if you can’t find it
as often, this is thrown out when unpacking. If you need to order one, it is Sonifex part number 45-505.
Q :
What type of remote lamp should be used ?
A :
The remote lamp type should be 18V at 40mA.
Q :
I want the remote lamp to be ON to indicate line diverted, but not dim when the line is not diverted. How do I do this ?
A :
Remove R12 from the circuit on the HY02-4 PCB. It should work ok then.
Q :
I want to use a LED for the remote lamp. How do I do it ?
A :
As above, remove R12 from the circuit on the HY02-4 PCB. It should work ok then.
Q :
What are the connections for the telephone wire ?
A :
The telephone line is connected via the white and red wires on the connector. So you know which pin is which, the
latch is adjacent to Pin 6.
Pin 1 :
Not used
Pin 2 :
White wire, BT line A
Pin 3 :
Green wire, Earth recall
Pin 4 :
Blue wire, Ringer
Pin 5 :
Red wire, BT line B
Pin 6 :
Not used
Q :
The handset connected to the unit doesn't ring. What's wrong ?
A :
If the handset connected to the unit does not ring but still works o.k., the ringer shunt wire (blue wire pin 4) has
become open circuit. Or, if it has never worked since installation, the extension wiring will need checking.
Q :
What is the power consumption of the HY-02 telephone hybrid ?
A : <
6W for HY-02, HY-02S, RD-02R and <12W for HY-02T and HY-02D. The RD-02 draws power from a connected unit.
Q :
The telephone hybrids don't automatically disconnect on dial-tone. Why not?
A :
This is correct as there is no dial tone disconnection unless the HY-DTD dial tone detect option has been added. If the
HY-DTD option has been added and you still have this problem, then the unit is probably connected to a PABX, or a
non British Telecom network (i.e. not used in the UK) and so, the dial tone detect circuit needs changing. Contact
Sonifex technical support, [email protected] for further information.
Q :
The telephone hybrid unit keeps "dropping the line". How can I stop this happening?
A :
Firstly, try disabling the k-break function of the hybrids - disconnect the link wire between terminals T2 and T3.
If you still have a problem once the k-break is disconnected, please contact Sonifex technical support,
