Documented specifications
Algo · Algo listed the 8450 as a current IP Console, updated its user guide on October 9, 2026, and included model-specific changes in the 2026 firmware 5.7 release. Exact ordered variant, shipped hardware, installed and approved firmware, platform licence, regional availability, price, warranty and remaining support require current confirmation.
| Specification | Documented value |
|---|---|
| Variants | 8450SG desk or wall version has the gooseneck microphone and backlit action button; 8450R is the rack-mounted version without those two controls Source ↗ |
| Display and layout | 10.1-inch colour touchscreen with configurable screens and button layouts; interface state does not establish remote delivery Source ↗ |
| Control paths | SIP, multicast and REST API are documented as distinct integration paths Source ↗ |
| Live paging | Gooseneck microphone is required for documented live SIP or multicast paging actions and is an 8450SG feature Source ↗ |
| Operator controls | Product material lists five passcode-controlled user access levels plus confirmation and password-protection options Source ↗ |
| Inbound activation | Up to ten inbound SIP extensions can map to different button identifiers; hanging up does not itself cancel the triggered action Source ↗ |
| API authentication | REST API is disabled by default; the guide recommends HMAC-SHA-256 Standard authentication, limits Basic to HTTPS and warns against None Source ↗ |
| Power and location | Guide specifies dry indoor use at 0–40 °C and an IEEE 802.3at PoE+ or 802.3af PoE network connection Source ↗ |
| Provisioning and files | Supports model and MAC-specific provisioning; configuration, certificates, licences, tones, icons and other files require controlled backup and restore Source ↗ |
| Current firmware evidence | Algo announced firmware 5.7 features for the 8450 in 2026; the announcement and download surface do not prove one console runs or is approved for that release Source ↗ |
Unlisted fields remain unverified. Platform compatibility and remaining support life require confirmation for the exact ordered model.
Freeze 8450SG or 8450R before designing the workflow
Algo publishes one 8450 family with different physical variants. The 8450SG provides the gooseneck microphone and backlit action button for desk or wall use, while the 8450R is rack-mounted and does not carry those two controls in the current feature matrix. Record the exact order code, mount, attached controls, switch port, power negotiation, installed firmware and screen configuration.
Do not copy a live-page or push-to-talk acceptance result between variants. A touchscreen action may still initiate a stored announcement, SIP call, multicast or API request, but the operator, audio source and physical confirmation path must match the installed hardware.
Trace one action through its actual transport
The 8450 supports one-way SIP calls with live or stored audio, direct multicast to configured zones, and REST API commands to other devices. Record the selected screen and button identifier, operator, protection result, path, SIP destination or multicast zone, request and response, target endpoint, audible or visual output, completion and cancellation.
Algo says local multicast can provide paging continuity when the phone system is unavailable. That statement remains conditional on power, the local network, multicast configuration, console state and functioning receivers. It does not establish internet independence for every integration, end-to-end redundancy, recipient attention or guaranteed emergency delivery.
Protect every local and remote activation path
The guide distinguishes physical button protection, REST API authentication and passcode protection for inbound SIP extensions. REST API support is disabled by default; Standard authentication uses an HMAC SHA-256 digest, Basic should be used only over HTTPS and unauthenticated access is not recommended. Keep the sender and receiver credentials, clocks, NTP state, certificates and target addresses observable without publishing secrets.
Change default administrative and API credentials, define operator access levels, restrict management reachability and verify that remote activation cannot bypass the intended confirmation. Up to ten inbound SIP extensions can map to buttons, and the guide warns that hanging up does not cancel the activated action; configure and rehearse an authorized stop path separately.
Control messages, files, provisioning and firmware as content
Stored tones, recordings, icons, address books, certificates, licences, backgrounds and logos are operational content, not decoration. Inventory ownership, approved wording and language, file hash or revision, audience, expiry and rollback. A factory reset can remove uploaded files, while a restore can reintroduce old credentials, tones or certificates.
The 8450 supports model and MAC-specific provisioning plus central provisioning options. Algo also announced firmware 5.7 features in 2026. Preserve installed versus available firmware, signed source, configuration backup, change approval and post-update acceptance. A current release announcement is not proof that one deployment should upgrade or that every integrated endpoint supports the new behavior.
Accept daily paging and emergency workflows separately
Test startup, operator login, live microphone, delayed page, stored announcement, SIP call, multicast, API action, inbound-extension activation, relay-triggered action, target-zone accuracy, visual state, stop controls, receiver output, network and PBX loss, PoE restart, restore and user handover. Verify audio intelligibility and visual awareness with the intended recipients in the actual spaces.
Keep school, healthcare or industrial emergency procedures within the responsible authority's approved plan. The 8450 is an initiating control surface, not proof of recipient coverage, evacuation compliance, public emergency-service access or human response. No console, PBX, API, multicast domain, alert, announcement, receiver, emergency procedure, availability, compatibility, price or live event was inspected or tested for this reference.
