A push-to-test indicator lamp allows a documented local test of the lamp circuit.

## What it represents

A push-to-test indicator lamp allows a documented local test of the lamp circuit. The test path and normal indication path must be distinguished.

## How to read it

- A successful lamp test does not necessarily verify the monitored process contact.
- The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation.

## Information to show or reference

- Show normal signal source
- Show test connection
- State lamp supply and colour

## Important distinction

Lamp test verifies an indication path; it is not automatically a complete alarm-system test.

## Facts

- Drawing role: Visual signal
- Representation scope: Functional concept; not an official standard graphic or a product footprint
- Public vendor block reference: HLT1RP, VLT1RP (Autodesk identifiers; not IEC symbol numbers)
- Identifier status: The short label is a functional lookup label, not an assigned IEC or IEEE symbol number. Any separately listed Autodesk code is a verified vendor block name.
