WS4933/WS4933EU (433MHz)/WS8933 (868MHz) Wireless Carbon Monoxide Detector
Installation and Operating Instructions
Read these instructions thoroughly before installation and use of the WS4933/WS4933EU/WS8933
The WS4933/WS4933EU/WS8933 is designed to monitor the CO gas level in res-
idential dwellings and give early warning before dangerous levels are detected. This
device is intended to be used with a compatible wireless alarm system. The detector
consists of an electrochemical carbon monoxide sensor assembly coupled to a wireless
transmitter.
The Wireless Carbon Monoxide Alarm communicates with the control panel and can
send alarm, tamper and battery condition messages to the system receiver.
Caution: The detector expiry date is stamped on the detector. After the expiry date,
the detector should not be used - do not wait for end-of-life indication!
CAUTION: Unauthorized removal of the unit from the mounting bracket will
initiate a tamper alert.
Warnings:
The WS4933/WS4933EU/WS8933 Series Wireless Carbon Monoxide Detector shall
be installed and used within an environment that provides the pollution degree max 2
and overvoltages category II in NON HAZARDOUS LOCATIONS, indoor only.
The equipment is designed to be installed by SERVICE PERSONS only; (SERVICE
PERSON is defined as a person having the appropriate technical training and exper-
ience necessary to be aware of hazards to which that person may be exposed in per-
forming a task and of measures to minimize the risks to that person or other persons.)
Failure to properly install, test and maintain a CO detector may cause it to fail, res-
ulting in loss of life. Installation of the CO detector should not be used as a substitute
for proper installation, use and maintenance of fuel burning appliances, including
appropriate ventilation and exhaust systems.
This carbon monoxide detector is designed for indoor use only. Do not expose it to
rain or moisture. Do not knock or drop the detector. Do not open or tamper with the
detector as this could cause malfunction. The detector will not protect against the risk
of carbon monoxide poisoning if not properly installed.
CAUTION: This device will only indicate the presence of carbon monoxide gas at the
sensor. Carbon monoxide gas may be present in other areas. This carbon monoxide
alarming device is designed to detect carbon monoxide gas from ANY source of
combustion. It is NOT designed to detect smoke, fire or other gases unless the product
has been investigated and determined to comply with applicable requirements.
