Powerful Gas Operated Alarms
AVAILABLE VERY QUICKLY
Delivered promptly and works well.
I bought the PIR alarm with keypad and an external alarm. Both were delivered promptly and work well. Be aware that the external alarm will sound as soon as batteries are fitted until it is plugged into the PIR unit so plug it in first before fitting the batteries. I cut off the connector for the external reed switch and connected into my chain of existing switches and everything works fine.
