FAI Input Connection Methods
The Beacon FAI input is the most flexible we have yet seen in the industry. It may be activated
by any common means found in the access and fire industry.
When activated, this input will disable the Beacon DC2 output and enable the DC3 output.
The MB8 and CMB8 accessory boards will follow the Beacon FAI input.
Methods of activation include:
1. Relay contact transfer using internal voltage
source:
a. Normally closed.
b. Normally open.
2. Power from external voltage source:
a. Switched positive.
b. Switched negative.
3. Open collector connection:
a. Internal voltage source
b. External voltage.
4. Direct to NAC loop:
a. DC polarity reversal
b. DC polarity reversal with horn/strobe
synchronization
