- The automatic detection system shall comprise cross-zone detection to activate before activation of the gaseous fire suppression system. The Contractor shall provide all control panel and necessary relay for alarm connection to MAP.
- Upon activation of the gaseous fire suppression system, it shall cut off the operation of the computer air-conditioning units, which are installed by others. The Contractor shall provide and connect all the necessary controls, relay, cable, conduit, etc to effect this interlocking operation.
- Activation Stage 1 (1st Alarm)
When the first detector of a particular zone is activated, the 'Alarm' LED on the Control Panel shall be blinking and the following functions shall be executed: -
· The alarm bell shall sound.
