DAB1 DISTRIBUTED AUDIO SYSTEM
Keypad Connections
1. In direct runs from keypad to
controller, pull a length of CAT5
wire from every keypad mount-
ing location to the DAB1
location. The maximum length of
any single CAT5 cable is 1000’.
2. Terminate each CAT5 cable with
RJ45 connectors on each end.
Follow the TIA 568B wiring
standard (see
Figure 26
).
3. We strongly recommend testing your connections with an RJ45 network cable tester to check for cable continuity,
miswiring, open connections, shorted connections or cross-pinning.
4. Connect the CAT5/RJ45 cable to the RJ45 Connection Jack on the back of the Keypad and to the zone’s Keypad
Controller Port on the DAB1 (see
Figure 27
).
External Keypad Power (see Figure 28)
The DAB1 supplies 1A of total keypad current through its keypad connections.
When the rear-panel Z
ONE 4 – 6 KEYPAD POWER switch (see
Figure 28
) is in the INT
(internal) position this current is evenly divided between all six Zone Keypad Connections.
When the switch is in the EXT (external) position, the DAB1 supplies all 1A of current to
Zones 1 – 3, while Zones 4 – 6 must be powered by an external PS2 power supply
(available separately) connected to the Z
ONE 4 – 6 KEYPAD EXTERNAL POWER Connection.
The table below shows how many of each type of keypad can be used with internal keypad
power, and with a PS2 connected to the K
EYPAD EXTERNAL POWER Connection:
See page 49 for additional information about connecting K1 and K2 programmable keypads.
