2.8.1 Alarm Delay

The detector is equipped with an Alarm Delay option, which provides

programmable time delays with settings at:

• Antiflare* (default)

*The Antiflare mode is selected to prevent false alarms in locations

where fast flares may be present. The Time Delay for fire alarms in this

mode ranges from 2.5 to 15 seconds (usually, less than 10 seconds).

Other delays settings are available:

• 0, 3, 5, 10, 15, 20 or 30 seconds

When an Alarm (Detection) level condition occurs, the detector delays the

execution of the Alarm outputs by the specified period of time. The detector

then evaluates the condition for 3 seconds. If the Alarm level is still present,

the Alarm outputs are activated. If this condition no longer exists, the

detector returns to its standby state.

The Alarm delay option affects the output relays and the 0-20mA. The LEDs

and outputs indicate warning levels during the delay time only if the fire

condition exists.

2.8.2 Address Set-up

The detector provides up to 247 addresses that can be changed with the

RS485 communication link or the HART protocol.
