Door-Holding Systems

C2 MONO-ZONE MICROPROCESSOR

Certified in accordance with EN 1154-2 and EN 1154-4 standards.
The processor was designed and built in conformity with UNI EN 1154 standards, which regulate processors for fire alarms and related accessories which each must conform with EN1154 standards.

This is a control unit which administers the door-holding electromagnets for fire doors, where standards require consideration of every possible and imponderable event that could happen during normal functioning. The following, therefore, are subject to constant monitoring: all exits towards the smoke and heat detectors, the alarm and reset buttons, the external siren and the charge of the two batteries. The microprocessor itself, which functions as the brain of the system, is constantly monitored at regular intervals by a specific system routine that checks for proper functioning of the operational software. Any hitches, breakdowns or malfunctions are signaled by one of the ten LED diodes on the front panel, and the internal buzzer provides an additional acoustic signal for specific cases. Alarm or breakdown situations can then be reset at three different levels depending on the seriousness of the event: by a button located near the microprocessor, by a first button on the front of the microprocessor unit and by a second button on the same panel that requires key selector activation (key in possession of the safety manager). A fourth reset level is then supplied for the circuit only (operation executable by authorized technical personnel only).

ATTENTION
According to standard EN 1154-4, it is obligatory for the mono-zone processor to be equipped with:

• Nr. 1 heat/smoke detector RFC certif. EN 1154-7
• Nr. 1 pair of buffer batteries
• Nr. 1 external electronic siren certif. EN 1154-3
• Nr. 1 alarm activation button certif. EN 1154/11

• max. Nr. 5 RFC heat/smoke detectors
• max. Nr. 5 alarm activation buttons
• max. Nr. 2 electronic sirens
• Nr. 4 EM or EMP electromagnets
• Nr. 2 buffer batteries

RFC HEAT AND SMOKE DETECTOR

Certified in accordance with UNI EN 1154-5 and EN 1154-7 standards.
RFC heat and smoke detector characterized by white ABS casing. Optical/thermic operation with intervention temperature to be set between 54 and 65°C. To ensure proper functioning, the detectors must be subjected to regular 6-month maintenance checks. Please note that it is inadvisable to position the sensor where strong air currents are present.
