ZP755W-2R Addressable Weatherproof Sounder
Installation Sheet
Description
The ZP755W-2R is an addressable, weatherproof sounder,
designed for use on Ziton addressable fire detection and alarm
systems. The sounder is rated for outdoor, wet applications. It
provides audible warnings from a single, addressable, loop-
wired unit.
The device includes a volume control, an address-setting
switch, programmable tone settings, and a pair of jumpers to
select the operating power — from the analogue addressable
loop or an external supply.
Installation
To install the device follow these general steps.
1. Wire the PCB.
2. Set the operating power.
3. Set the address.
4. Set the operating mode.
5. Set the tone.
6. Set the volume.
7. Mount the sounder.
The details of each step are given below.
Wiring the PCB
Connect the loop wiring and the optional external power cables
to the terminals on the PCB as shown Figure 1.

Setting the operating power
The sounder includes a pair of power selection jumpers, J1
and J2. To select the source of the sounder operating power,
position the jumpers as shown in Figure 2.

Note:
When using an external power supply, use only one that
is CE and EN 54-4 compliant to power all the sounders on the
same loop.
Setting the address
The sounder includes a seven-segment DIP switch (SW1) for
assigning device addresses. Each switch segment has a
decimal value as shown in Figure 3. The address is the sum of
all the switch segments in the ON position. The switch is used
to set the device address in binary code. The switch may be
set to represent any address from 1 to 127.
For example, to select a device address of 007, set SW1-1,
SW1-2, and SW1-3 to the ON position and the remaining
switch segments to the OFF position.
