VoIP Telephone.
Connection types and ratings:
•
LAN connection - RJ45 on Cat5 or Cat5e UTP cable
•
All other connections - 0.14mm² to 2.5mm² (26 to 14awg) for
rigid/solid cables, 0.14mm² to 1.5mm² (26 to 16awg) for
flexible/stranded cable.
Refer to safety information in section 5.2
Output 1
- rating 2A at 250Vac, 2A at 30Vdc
Output 2
- rating 2A at 250Vac, 1A at 24Vdc
(Note: for Output 1, a continuous current of 2A will cause a 22°C temperature
rise to the PCB area close to the terminals after 10mins. This will not cause
the telephone to malfunction, but it may result in this area becoming hot
especially in high ambient temperatures. Avoid operating Output 1 at high
currents in high temperatures. If the current is below 1A this temperature rise
will be less than 5°C. Output 2 will not give any significant temperature rise up
to its rated current of 3A)
External power supply
- 24-48Vdc, 200mA
Control inputs
- for connection to voltage free contacts only. Internal pull-up
resistor source current = 300uA. These inputs form part of an ES1 circuit and
precautions must be taken to prevent hazardous voltages being applied to
these circuits
5.8. Help Point Installation
1. To prepare for installation, remove the faceplate from the rear enclosure
(if supplied) by undoing the four retaining screws. A 3mm Allen key is
required.
2. Help Point telephones are intended for vertical installation to a wall or
pole or flush-mounted into a vertical surface. Select the required
