Exitguard Door Alarms
The Exitguard satisfies the requirements of both fire and security officers.  Exitguards are competitively priced and are a cost effective way of protecting sensitive doors. Ideal for Hotels, Supermarkets, Warehouses, Public Buildings, Garages, etc…  Battery, Mains and 12volt dc powered versions are available. All are supplied with a magnetic door contact, fixing screws, and a self-adhesive door warning label. This new version is backwards compatible with older Exitguards. Keypad and Keyswitch versions available.

General Purpose Indicator
The Multiguard is a six-zone indicator used in the emergency alarm market.
The basic Multiguard has facilities for global silence and reset. All versions can be supplied with and without an integral power supply and stand-by battery.
Look-a-like repeaters enable simultaneously indication at a number of different locations, and if required can have control facilities. A separate relay interface card is available to give zonal output to other systems such as CCTV switchers or BMS systems.
The Multiguard enclosure is designed in such a way that units can be stacked forming 12, 18 or 24 zone indicators. For larger systems we can offer a custom designed solution.

Disabled Toilet Alarm
Comprehensive BS8300 compliant disabled toilet alarm kits are now available from Hoyles. The new AIDALARM kits are available in plastic or stainless steel finish and include all equipment required to create a disabled toilet alarm to satisfy the requirements of the Disability Discrimination Act. The AIDALARM is operated by a pull cord and can be reset from a button inside the toilet cubicle or from the control unit which also provides audible and visual indications. The Aidalarm can be extended to give remote indication and has programmable sounder tones to suit different environments.
The kits comprise the Aidalarm control unit, pull cord, reset button and a self adhesive disabled toilet sign along with full installation instructions.

Keyguard
The Keyguard is not your average key box it has been designed with safety as well as security in mind. The Keyguard is able to take both KEYS and CARDS and is available with or without alarm facilities, either battery powered alarm or simply as a single pole micro switch making it suitable for many applications. The window is designed in such a way that it cannot be refitted after removal. The Keyguard plastic window enables it to be used in such areas as schools, food preparation areas and swimming pools. There are no shards of glass or sharp edges that could cause injury. 

Standalone Fire Alarm GX20e
The GX20e is the simple and economic fire alarm. Featuring an integral call point and high power (105db @ 1m) piezo sounder. The two PP3 batteries are supervised by an integral battery fault monitor. A keyswitch is used to silence or restart the alarm. The GX20e is intended as a manual fire alarm for small buildings where a single standalone system is sufficient, however, up to four units can be linked together. The GX20e does NOT take smoke or heat detectors. For larger systems where callpoints and sounders must be interconnected or there is a requirement for smoke detectors we would recommend our GX32 System.
