There are different types of gas leak detection devices. Some can be installed on the wall like a smoke detector. A good place to start looking online could be www.Amazon.com
Gas detection systems monitor for the following types of gases: (Combustible) Methane, Ethane, Propane, Butane, (flammable) methanol, gasoline, acetone, toxic gases and oxygen depletion.
The name of one such gas leak detection device is called Photoacoustic Multi-gas Monitor. This device and others can be found here: http://www.lumasenseinc.com/EN/products/gas-monitoring-instruments/gas-monitoring/innova-1314.html.
No, ammonia is not a combustible gas. It is a highly reactive gas that can contribute to combustion if in the presence of other combustible materials, but it is not considered combustible on its own.
There are several types of oxygen gas detectors, which can include the detection of toxic and combustible fumes. Oxygen gas detectors can be bought on this website: http://www.gassniffer.com/bw-honeywell-gas-detectors.html?gclid=CJHD-emrkaoCFUUZQgodyWZRyg
