The Firewatch and Fireguard systems provide a simple and convenient means of shutting down and isolating gas systems in Laboratories, as required by IGE/UP/11 (previously British gas IM 25) and in Commercial kitchens as required by BS 6173:2009. It also gives compliance with GSIUR 27(4).

The systems also provide emergency stop in case of an incident and ensures that when the gas is restored all the gas outlets have been closed and the gas pipework has no major leakage.

The control panel can be fitted with an optional interface PCB to allow control from time clock, BMS systems, fire alarm systems etc. Any number of remote KO buttons may be used, either as mushroom buttons, flush buttons or yellow break glass knockoffs


KITCHENS


When used for controlling kitchens, the control panel can also be arranged to shut down the electrical supply. This enables one set of remote stops to isolate all electrical and gas equipment. If an existing electrical isolation system exists, then the power supply for the Firewatch can be picked up from this circuit or via its contactor. The isolation stop circuit will then shut down all utilities.


It is of course necessary to separate the lighting circuits and any essential power circuits e.g. freezers to ensure only the potentially dangerous circuits are shut off.


SCHOOLS, LABORATORIES


If vandalism is a cause for concern it may be desirable to isolate the water supply at the same time as the gas supply. This can be done by fitting a solenoid valve in the water supply pipe to operate via the Firewatch panel voltage free contact, in a similar manner to that described above or using our MK 5.


We can supply all necessary wiring diagrams, layouts and solenoid valves. When the Firewatch Control Panel is supplied for either of the above duties the standard fascia has an overlay indicating the different services being controlled.
