5.1.1 Supervision of Devices
The loop interface software continuously supervises the devices on its loop against those
found during configuration for the following conditions:
• Device missing.
• Unconfigured device responding.
• Two or more devices responding to the same address.
• Wrong device type.
A communication or addressing error on a device is reported as a trouble on the associated
zone LED as configured. The detectors may be configured as non-verified or verified alarm
inputs.
5.1.2 Device LEDs
• Polling the devices on the loop causes the LED to flash normally.
• All device LEDs can be suppressed via the configurator. Suppressing the device LED’s
causes sounder or relay bases to not operate. AP devices do not support sounder or
relay bases.
• Activating devices on the loop (alarm for an input device, active for an output device)
illuminates the LED steady.
• The maximum number of active Advanced Protocol and/or CLIP devices with their LED
illuminated steady is fifty (50) per loop.
5.1.3 Alarm Conditions
Alarm conditions are determined by the system continually polling the analog devices and
comparing the reported value against stored thresholds for pre-alarm and alarm conditions. An
agency approved range of thresholds is provided for each type of analog device (except for
contact devices).
Devices can be individually configured with 2 separate thresholds, “day time” and one “night
time” or after hours operation; i.e. a device may be configured to a low sensitivity for “day time”
and high sensitivity at “night time”. The day time threshold will be used unless the after hours
operation is active. To configure threshold settings, Enable Auto After Hours must be selected
in the configurator.
