constNT × contrLS

ALG's two safety and controls platforms — emergency egress and networked controls — cover every code requirement from UL 924 to Title 24 to ASHRAE 90.1. One submittal binder. One warranty card. Both halves of the compliance package.

Why ALG · 04
Spec · Submittal · Warranty

One submittal binder. One warranty card. Both halves of the compliance package.

One Submittal
Life-safety and controls on one spec package
When the egress fixture, the occupancy sensor and the relay all ship from ALG, the contractor pulls one submittal binder and one warranty card. No three-vendor finger-pointing on punch list.
Code-Aligned
UL 924 + Title 24 + ASHRAE on the same drawing
Emergency 90-minute discharge meets UL 924; daylight + occupancy + scheduling meet Title 24 §140.6 and ASHRAE 90.1 §9.4. Every claim ships on the spec sheet, not the marketing page.
ⒶCS-Ready
Every PRO+ luminaire pairs with the ⒶCS gateway
Bluetooth Mesh self-commissioning. Up to 250 nodes per gateway. Scheduling, daylight harvesting, occupancy, and demand response — without a separate panel or PoE backbone.
Field Reality:
The same drawing that pulls UL 924 emergency egress almost always pulls Title 24 occupancy + daylight. Pricing them together — same rep, same lead time, same warranty — is how the bid gets cleaner and the punch list gets shorter.
Spec Questions · 07
Frequently asked · pro buyer

The questions a contractor asks before pricing the job.

01
Is constⒶNT UL 924 listed?
Yes. Every Beacon-II, Sentry-LX, Lifeline, Watchman and Citadel SKU is UL 924 listed for 90-minute discharge. The UL file number prints on the spec sheet and on the housing label — drop it directly into the AHJ submittal.
02
Do contrⒶLS sensors meet Title 24 Part 6 and ASHRAE 90.1?
Yes. Periscope occupancy and daylight sensors are CEC Title 24 Part 6 §140.6 and §141.0 compliant out of the box, and meet ASHRAE 90.1 §9.4 auto shut-off + daylight-zone requirements. Programming is field-default; no commissioning trip required for code minimum.
03
Is the ⒶCS by ALG App a separate panel or part of the luminaire?
The ⒶCS Hub is a small wall- or DIN-rail gateway — Bluetooth Mesh on one side, Ethernet/Wi-Fi on the other. Every PRO+ luminaire and every PRO+ control node speaks BLE Mesh natively, so the gateway commissions itself. Up to 250 nodes per gateway. No PoE backbone required.
04
How many nodes per ⒶCS gateway and is BACnet supported?
250 nodes per gateway. Multiple gateways federate over Ethernet for larger sites. BACnet/IP is included on the PRO+ gateway for BMS integration; demand response (OpenADR 2.0b) and scheduling ride on the same channel.
05
Can I order constⒶNT and contrⒶLS on the same PO?
Yes — same PO, same warehouse, same lead time. Submittal binder consolidates UL 924, JA8, DLC NLC5 and Title 24 documents under one project number. Warranty is 7 years on PRO and PRO+ across both collections.
06
What about retrofit — can ⒶCS retrofit existing 0–10V drivers?
Yes. The Glide-1V dimming module and MeshNode-5 wireless node attach to any 0–10V driver from any manufacturer. Field commissioning takes ~2 minutes per fixture using the ⒶCS App. No re-wiring of the line-voltage feed.
07
Does central battery (CBS) meet NFPA 110?
Citadel CBS systems carry NFPA 110 Type 10 / Class 1.5 listings (10-second transfer, 90-minute runtime). Higher classes (Class 2, Class 6) available on the 2200W chassis. Self-test, monitored output and remote dry-contact alarm standard on PRO+.
