HWB-416
K1095-1 08/03
Description:
A multiplexing 16 zone expansion board for apex control panels.
Specifications:
16 dry contact inputs
Contacts wired normally open or closed
Optional 4.7K End of Line resistors
10 second polling - trouble indication upon loss of communication
Power:
Current draw - 85mA
Source - 4 wire bus
Operating voltage - 9.5 to 14VDC
Wiring:
Observing proper color code, attach the HWB-416 to the 4 wire bus using four-wire stranded cable.
For wire runs up to 50 feet, 24 gauge wire is recommended and for runs over 50 feet use 22 gauge.
An HWB-416 can be wired directly to the control panel or daisy chained to any other 4 wire bus
peripheral in the system.
Each zone can be wired in one of three methods:
- With a 4.7K end of line resistor
- Fully Supervised with two 4.7K resistors (Selected in programming)
- Without an end of line resistor
See Wiring an Input in the Installation Manual for wiring an input with 1, 2 or no resistors.
Dip Switches:
An HWB-416 is two 8 input zone expanders on one circuit board. Each group of eight
(inputs L1-L8 and U1-U8) have separate dip switch settings. Depending on control panel support, up
to 8 groups with 8 inputs per section can be used per system (total of 64 expansion zones on 4
boards). To determine the number of zones supported by the panel being used consult the control
panels Installation Manual. Use the chart below to determine proper dip switch settings. Examples
of the most common dip switch settings are shown on the following page.
