Patent number: 8860573Abstract: The present invention is an alarm system comprising an alarm handset (10) having a housing (30), a detector circuit (100) having means (102, 104) for receiving a preselected signal from a remote transmitter (40) and generating a first detection signal in response thereto, first sensing means for sensing change in a preselected parameter of the handset, warning means (300) for generating a warning signal, alarm means (400) for generating an alarm signal and control means (500) responsive to receipt of the detection signal to activate the alarm means (400). The control means (500) is operable to activate the warning means in response to at least one of receipt of the control signal and sensing of the change in the preselected parameter of the handset.Type: GrantFiled: March 6, 2007Date of Patent: October 14, 2014Assignee: Fireangel LimitedInventors: Stuart Arthur Hart, Nicholas Alexander Rutter

Publication number: 20100117840Abstract: An alarm for detecting radiation and/or pollutants such as smoke, carbon monoxide or the like has a housing, a mounting plate for mounting the housing to a flat surface, cooperating means on the housing and the mounting plate engageable to secure the housing to the mounting plate, and an alarm circuit including a detector for detecting the radiation and/or pollutants. The alarm also has a switch in the alarm circuit in the housing and a magnet on the mounting plate, the arrangement being such that the magnet actuates the switch in response to engagement of the housing with the mounting plate thereby to arm the circuit. A battery compartment in the housing receives a battery for the alarm and stop means prevent proper engagement of the cooperating means in the absence of the battery. The mounting plate is generally planar having an upper surface and a through-opening for receiving a fixing such as a screw for fixing the mounting plate to a generally flat surface.Type: ApplicationFiled: April 11, 2008Publication date: May 13, 2010Applicant: FIREANGEL LIMITEDInventors: Nicholas Alexander Rutter, Stuart Arthur Hart

Patent number: 7262581Abstract: A rechargeable power supply including voltage protection means through voltage dependent disconnecting means. A rechargeable power supply comprises at least one rechargeable cell connectable to a power source, a Zener diode connected to the at least one cell, and a bipolar transistor or a FET for selectively disconnecting the Zener diode from the cell in order to reduce any discharge of the cell through the voltage protection means. The Zener diode and the transistor are connected together in series and jointly connected across the cell in parallel.Type: GrantFiled: May 7, 2002Date of Patent: August 28, 2007Assignee: Fireangel LimitedInventors: Nicholas Alexander Rutter, Stuart Hart
