network shall be self-operable and inter-connectable with at least 32 analogue addressed fire alarm network systems in big distribution systems. When additional detectors or buttons are needed in the system, these additions shall be made freely and this process shall not hamper the existing local addressing arrangement. The network shall contain at least 4 programmable audible alarm outputs as standard and specially controlled alarm and fault outputs shall be available for signalling to fire brigade or a remote fire-fighting centre or observatory. Different working schedules for day and night hours in the network shall be applicable. In case very low-density smoke is present, a pre-alarm function shall be available for early response from the network (response to fire before audible alarms activate). The network shall control all detectors constantly for pollution level and shall give a “Service required” warning when pollution is detected. Repeating panels and mimic panels shall be connectable to the network. All cables going to detection and alarm devices and all lines used for communication to remote control and inspection centres shall be continuously controlled for breakage, short circuit and fault currents. The network shall keep the last 200 events in its non-volatile memory. 

The fire alarm network shall contain a general fire alarm and fault lamp, individual alarm and fault lamps for each fire zone, illuminated alphanumerical gauge with at least 80 characters and local sound warning device. A mini type thermal printer shall be installable on the network when necessary. All regional fire lamps shall contain a zone number on their side to indicate their fire zone. In case the main supply is out, the fire alarm system shall be equipped with fully closed, impermeable type, maintenance-free batteries to carry out detection functions for at least 24 hours and to execute alarm, control and communication functions for at least 30 minutes at the end of this duration. Also, the UPS system in the administration building can be used for supply as well. The network earthing shall be made independently with required ohm value. The network shall be in accordance with TS EN 54-2 and TS EN 54-4 and shall be manufactured by a ISO 9001 quality certificated manufacturer. The supply and delivery of the network tested for operation, including all types of small materials. 

## Analogue Addressed Ionized Smoke Detector; 

The detector shall be sensible to smoke particles with sizes between 0.01 microns and 10 microns. The detector shall have a double-cubicle ionization cell to be immune to changes of humidity, ambient temperature, etc. The detector shall send the measured analogue smoke levels to the control panel as analogue information, the sensitivity, calibration and working performance of the electronic circuit shall be tested by the detector and this information shall be sent to the control panel via circuit cable. The detector shall contain at least one LED light for remote visual control and shall be suitable for parallel warning lamp connection. The detector shall be mountable and removable by a specific socket. The addressing of the detector shall be made by any position switch or manual type detector programming devices. The detector shall be in accordance with TS EN 54-7 and shall be manufactured by a ISO 9001 quality certificated manufacturer. 

## Analogue Addressed Temperature Detector; 

The temperature measured by a semi conductive temperature detector shall be sent to the control panel as analogue information. The detector shall be programmable to operate as a constant temperature detector or temperature increase rate detector and the constant temperature activation value shall be adjustable to at least one of the 4 different temperatures. The detector shall send the measured temperature levels to the control panel as analogue information, the sensitivity, calibration and working performance of the electronic circuit shall be tested by the detector and this information shall be sent to the control panel via circuit cable. The detector shall contain at least one LED light for remote visual control and shall be suitable for parallel warning lamp connection. The detector shall be mountable and removable by a specific socket. The addressing of the detector shall be made by any position switch or manual type detector programming devices. The detector shall be in accordance
