- New generation Electrochemical sensor checks for CO concentration every 70 seconds. The sensor has a high level of selectivity. No false alarms when exposed to the following interference gases for 2 hours: (as per UL2034sec.38) Methane 500ppm, Butane 300ppm, Heptane 500ppm, Ethyl Acetate 200ppm, Isopropyl Alcohol 200ppm, Carbon Dioxide 1000ppm.
- Manual Test/Hush button: tests the alarm (when pressed and held) and silences false alarms (when pressed and released). This will silence the unit for 4 minutes before resetting. It will only silence once until the gas clears.
- Supplied with “Easi-fit” surface mounting plate, with integral terminal block, cable cover and fixing screws. The base plate has trunking knock outs for 16 and 20mm trunking.
- The unit has a tamper resistant cover, which cannot be removed without the use of a tool. An optional locking screw can be screwed into the side to prevent removal.
- A remote relay option is available which has multiple uses, including switching a gas solenoid shut off valve.
- Separate green indicator light confirms integrity of mains power supply.
| - Automatic self-checking feature – amber light will flash and the alarm will beep every 40 seconds if it detects a fault.
- Automatic reset facility – alarm resets when CO gas is cleared.
- The alarm carries the Kitemark to indicate type testing to BS EN 50291:2001.
- Low and high level indicators – red indicator light flashes every 2 seconds at 50ppm CO (sounder operates within 60-90 minutes); flashes twice every second at 100ppm CO (sounder operates within 10-40 minutes); flashes 4 times per second at 350ppm CO (sounder operates within 3 minutes).
- Built in sounder to give a minimum output of 85dB (A) at 3 metres. Modulated sound output – 3 rapid pulses, followed by a 1.5 second pause, repeated until reset. This easily differentiates it from a typical smoke alarm.
- Operating temperature range: -10oC to +40oC (14oF to 104oF). 15% to 95% relative humidity (non-condensing).
