Overview

Loop Parameters

Loop	Current Draw	Duplicate Pulse Threshold	Normal Pulse Threshold	Set New Thresholds	XP95 LED Flash on Poll

Devices (a Missing device can be forgotten to clear it from this list - e.g. after a temporary DIP-switch re-address test)

Loop	Addr	Type	Analog	Status	Updated

Board & Loop Admin

Quick Actions

Onboard Diagnostic LEDs (the ALM2 board's own Red/Yellow/Green - not a loop device, set-only)

Red: Yellow: Green:

Selective Polling / Commissioning (no addresses commissioned = full loop always polled, which is your current state)

Loop	Addr	Type	Action

Detector Controls

Detector Sensitivity

Loop	Addr	Type	Current Mode	Set Mode	LED Flash	Rapid Drift Comp.

Alarm Thresholds (write-only - the protocol has no command to read back the currently configured value; defaults are pre-alarm 45, alarm 55)

Loop	Addr	Type	Pre-alarm (0-127)	Alarm (0-127)

Drift Compensation

Loop	Addr	Type	Clean-Air Value	Dirty	Reset to Default

Backup/Restore (bulk 126-address table, Command 1D):

Switch Monitors, MCPs & Relays

Switch Monitor / MCP Control (write-only - no read-back for these bits; per-row table below is switch monitors/MCPs only, but the bulk buttons also include detectors - same output bit triggers Self Test on both device families)

Loop	Addr	Type	Self Test	Integral LED

No switch monitors / MCPs detected yet.

Output Control (quick action - any non-detector, non-sounder device: relay modules, switch monitor/MCP LED and self-test bits, etc.)

Device: Output bit:

Advanced (any device, any loop/addr, e.g. Beacon/Sounder control bits once a sounder is added): Addr: Bit:

Sounders & Discovery Groups

Discovery Group / Sounder Broadcast (UNTESTED - no sounder beacon on this loop yet)

| Loop: Group: Volume: Tone: Output bits:

Sounder Beacon Settings (appears automatically once a sounder beacon is detected on the loop)

Loop	Addr	Type	Current Settings	Set Groups (comma-separated 0-15)	Set Volume/Tone	Noise Pollution

No sounder beacons detected yet.

Integral Output Control (UNTESTED - this ALM2-20 has 0 integral outputs; implemented per spec, packets send without protocol errors, but no observable hardware to confirm against)

Loop: Output(s): 1 2 Pattern:

Custom pattern (0/1 per 1/4s, e.g. 1100110011001100):

Pulse: s

Discovery Device Data

User Data (4 bytes non-volatile - site ID or install/service date, applies to every Discovery device)

Loop	Addr	Type	Current Value	Set as Text (up to 4 chars)	Set as Date
