Page 50: Local Control Station Blc1
The Local Control Station (BLCS1) provides for the manual release and discharge inhibit of the gas extinguishing agent. BLCS1 is interfaced to Brooks FT2GAS control panel via a supervised 4 wire connection. The GAS RELEASE function provides a manual initiate switch, incorporating a two-step action which initiates the normal system discharge sequence including fire and evacuation alarms, time delays, and equipment shutdowns and overrides the discharge inhibit switch. -
Page 51: Tone And Voice Sounders
Tone only relies upon the occupant’s awareness of the tones meaning and purpose. The Brooks electronic sounder consists of a speaker and digital voice/tone module which can be custom programmed for tonal frequency, voice message and language to meet specific client needs. - Page 52 Rev No. 1.3 Operation The BROOKS electronic sounder has two inputs, typically used for Alert and Evacuation but may also be two evacuation signals providing the same tone but differing language messages. The sounder requires a 24Vdc signal applied at the appropriate polarity. When power is applied to the digital voice/tone module the unit will sound the tone for approximately 10-12 seconds followed by a digital voice message.
