4. It may be connected with a local manual/auto control box for setting the operating mode of the
system (the local manual mode is preferred).
5. It may be connected with an agent drop display panel to give agent drop alarm signals.
6. It provides both single fire alarm output function and compound fire alarm output function. The
output form may be either passive node output or
＋
24V active node output. It may be used as a
closed signal for controlling equipment concerning ventilation, air-conditioning, etc.
7. It provides a drive output function for the RELEASE indicator.
8. It provides a drive output function for the alarm bell and the horn/strobe. Both the alarm bell and the
horn/strobe can be muted through the peripheral MUTE button or the HORN/STROBE
START/STOP button and the ALARM BELL START/STOP button on the panel.
9. It provides independent drive output ports for the electromagnetic valves and supports a starting
current of 3A (24V) for the electromagnetic valves (electric detonators).
10. It can preset an automatic start delay time of 0~30s for the electromagnetic valves (electric
detonators) through the jumpers on the display panel and displays the start countdown. The delay
manner of the manual start may also be set by the user through the jumpers on the display panel,
too.
11. It provides an open circuit fault detection function for the input circuits and a short or open circuit
fault detection function for the output circuits (active outputs).
12. It can monitor various kinds of faults. After the faults are eliminated, it can recover automatically and
needs no human intervention.
13. It uses WATCHDOG technology to make software run stably and reliably.
14. It uses an adaptive technology for the hardware power supplies to enable the system to operate
stably in case of abnormal fluctuations of the external power supply.
15. It can realize AC/DC full electronic switching that is reliable, smooth and seamless.
16. The standby batteries have an over-charge and over-discharge protection function and have their
states under intelligent monitoring, thus prolong their service lives.
17. The system has a low-power consumption design, and the DC power supply can operate for more
than 48 hours continuously.
18. The key lock is designed with a password protection function to prevent miss operations.
19. It has a historical information recording function and can record 999 instances of fire alarm
information, fault information and release information.
