WS4913 - DSC Wireless Carbon Monoxide Detector
Please Note: The DSC WS4913 wireless carbon monoxide detector has been discontinued and replaced by the WS4933 model number.
DSC WS4913 Product Description:
The DSC WS4913 is a wireless indoor electrochemical carbon monoxide detector which is effective for detecting any buildup of carbon monoxide, also known as CO gas, in your home or office. Colorless, tasteless, odorless but deadly, carbon monoxide is impossible to detect without a warning device. The WS4913 wireless carbon monoxide detector is the perfect complement to a compatible 433 MHz wireless alarm control.
The WS4913 provides front-line protection against the silent threat of carbon monoxide poisoning. It has an electrochemical sensing technology that is highly sensitive, detecting even trace amounts of carbon monoxide. Once carbon monoxide is identified, the sensor is triggered, the alarm is activated and the wireless alarm panel is signaled. The detector sounds the 85dB alarm to warn residents to leave the home immediately and at the same time signals the compatible wireless security system to dial the GeoArm central alarm monitoring station to alert the proper authorities. Although the WS4913 works in tandem with the wireless alarm panel, it also works as a standalone detector that is not connected to an alarm panel and provides an alarm warning to residents inside the home.
Since CO gas moves freely in the air, the suggested location is in or as near as possible to sleeping areas of the home. The human body is most vulnerable to the effects of CO gas during sleeping hours. For maximum protection, a CO alarm should be located outside primary sleeping areas or on each level of your home.

DSC WS4913 LED Indicators:
Alarm Indications:
- Warm Up Mode: 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.
- Power on mode: All 3 (three) LEDs blink and the built in sounder beeps for 0.5 second as soon as the battery is installed.
- Stand-by mode: The green LED flashes once every 60 seconds, which means the unit is receiving power and also indicates it is functioning properly.
- CO Alarm mode: When the unit senses the concentration of carbon monoxide (CO) in the air around the device exceeds the "alarm" threshold , the red LED light flashes rapidly and built in sounder activates loudly repeating a sequence of 4 quick beeps followed by a 5 second pause.
- Low battery warning mode: Every 1 (one) minute the yellow LED flashes once and the built in sounder chirps once. This warning will continue for up to 30 days, but the battery must be replaced as soon as possible to ensure proper operation of the detector.
- Tamper mode: The built in sounder chirps once every 1 (one) minute and the yellow LED is on continuously until the WS4913 is mounted on the back plate bracket properly. If this trouble occurs ensure the device is correctly mounted.
- Trouble mode: If every 1 (one) minute the built in sounder chirps and the yellow LED quickly flashes 2, 3 or 4 times, an internal trouble has occurred and the CO Alarm will need to be replaced.
DSC WS4913 Product Mounting:
Installation Dont's:
- Where the temperature may drop below 4.4®C or exceed 37.8®C
- Near paint thinner fumes
- Within 5 feet (1.5 meter) of open flame appliances such as furnaces, stoves and fireplaces
- In exhaust streams from gas engines, vents, flues or chimneys
- Do not place in close proximity to an automobile exhaust pipe; this will damage the Alarm
- Keep the CO alarm away from excessively dirty, dusty or greasy areas such as kitchens and garages. Ensure adequate ventilation when using household cleaners and chemicals as these can affect the sensor
