WS4913 Series Wireless
Carbon Monoxide Alarm
Installation and Operating Instruction
This Manual shall be left with the
Owner / User of this equipment.
This product is intended for INDOOR USE
in Non-hazardous locations ONLY.
Read this instruction sheet thoroughly before installation and
use of the WS4913 wireless carbon monoxide alarm
Introduction
The WS4913 is a wireless electrochemical Carbon Monoxide alarm,
which is effective for detecting any buildup of carbon monoxide, also
known as CO gas, in your home or office. Your CO alarm includes the
following features (See figure 1 as below):
(1) Easy to install
(2) Continuous monitoring for presence of carbon monoxide
(3) A loud (85 dB) alarm when a buildup of carbon monoxide is detected
(4) A test button to provide visual and audible indication that the unit is
functioning
(5) Self-diagnostics to immediately indicate any troubles
(6) Seamless integration with DSC controls panels using the panel bell
and system keypad to annunciate carbon monoxide build up or
device
troubles
(7) Compliant with the requirements of UL Standard 2075

Operation
The green LED flashes approx. once every 60 seconds, indicating that the
device has power and is actively sampling the carbon monoxide level in
the air
During the first 5 minutes after inserting the battery, the orange LED
will flash every 10 seconds and the unit will chirp every 60 seconds to
indicate that the unit is in warm up mode.
CO alarm
The CO alarm will go into alarm when the concentration of carbon
monoxide (CO) in the air around the device exceeds the 'alarm' threshold,
During an alarm, the red LED light flashes rapidly and buzzer sounds with
repeating 4 quick beeps and pause 5 seconds and then 4 quick beeps.
After 4 minutes of being in alarm the pause between beeps will change to
60 seconds. The alarm will continue to sound until the concentration of CO
in the air around the CO alarm drops below the ‘alarm’ threshold or the
reset button is pressed.
When properly enrolled on a DSC control panel, which supports the
WS4913 Wireless Carbon Monoxide Alarm, the CO alarm will be
wirelessly communicated to the control panel. The control panel will then
annunciate the CO alarm using the control panel bell output and display
the alarm and zone number which generated the alarm on the system
keypad. At the same time the control panel will communicate the alarm
to the central station to dispatch the appropriate authorities. Please refer
to your control panel installation manual for details
ʳ
Tamper
The removal of the CO alarm from the mounting plate initiates a 'tamper'
The built in sounder on the WS4913 will chirp once per minute and the
yellow LED will be ON steady.
Placing the unit on the mounting plate will restore the tamper condition.
When properly enrolled on a DSC control panel the Tamper will be
annunciated. Please refer to the PC9155-433

WARNING!!
Use only the batteries as specified above. Use
of a different battery may have a detrimental effect on alarm
operation.
Installing/Replacing battery
(See figure 2 as below):
(1) Open the battery cover to expose the battery compartment.
(2) Remove the old battery and properly dispose of it as recommended by
the battery manufacturer.
(3) Note the polarity of the battery and ensure it is correctly installed as
per the polarity markings indicated on both sides of the battery
compartment, make sure to carefully seat the red battery warning flag
in the recess of the battery compartment.
(4) Gently close the battery cover. The battery cover of CO alarm will not
close if the battery is not properly installed.

Caution:
Constant exposures to high or low temperatures or
high humidity may reduce battery life.
This carbon monoxide alarm is designed to detect carbon monoxide gas
from ANY source of combustion. It is NOT designed to detect smoke,
fire or any other gas, unless the product has been investigated and
determined to comply with the applicable requirements.
The WS4913 has been designed to ensure that there is at least 30 days
of battery life remaining once the ‘low battery’ condition has been
annunciated and transmitted to the DSC control panel.
When the battery voltage is low the built in sounder on the WS4913 will
'chirp' once every 60 seconds and the yellow LED will flash once per
minute until battery failure. When properly enrolled on a DSC control
panel the ‘Low Battery’ will be annunciated on the system keypad and the
zone will show as being in Fault. Please refer to the panel
Installation
Manual
for details. Replace the battery as soon as possible after low
battery indication is provided.
Trouble Conditions
If the WS4913 self-diagnostics function detects a trouble condition it will be
indicated by the trouble indicator LED.
Malfunction (Error) mode
:
The yellow LED flashes 3 times and the
built in sounder chirps once every minute. This trouble indicates an internal
fault and the unit will need to be replaced.
Low sensitivity mode
:
The yellow LED flashes 2 times and the built in
sounder chirps once every minute. This trouble indicates an internal fault
and the unit will need to be replaced.
End of life signal mode
:
The yellow LED flashes 4 times and the built
in sounder chirps once every minute. This indicates that the WS4913 CO
Detector is reaching the end of this useful life (around 6 years after the unit
is purchased), please replace with a new WS4913 CO detector.
When properly enrolled on a DSC control panel the ‘trouble condition’ will
be annunciated on the system keypad. Please refer to the PC9155-433
panel Installation Manual
for details.
