The conventional 4-zone fire alarm control panel is the central component of a conventional fire alarm system. It is designed for applications requiring a smoke detector, siren, manual call points, and monitoring of an automatic water sprinkler system. Each zone can be deactivated with a button. The basic unit offers 1 to 8 trigger zones, and up to 32 zones for larger installations.
Specifications of the conventional 4-zone fire alarm control panel:
- This is a modular design; the panel can easily expand from 1 zone to 32 zones.
- 2-level control mode via locking
- 24V DC and 5V DC power output.
- Output of FIRE and FAULT signals.
- 2 general siren activations.
- Each zone has 1 input for circuit detectors
- Each zone can be deactivated by a button.
- RESET button to reset the panel.
- SILENCE button to stop the BUZZER and SOUNDS.
- EVACUATE button to immediately trigger a manual fire alarm.
- Battery undervoltage protection function: activates when the battery voltage is below 21V DC.
- The battery will be automatically shut off until mains power is restored.
- Optional GSM module for fire alarm via SMS
