Etlin-Daniels supplies emergency lighting and occupancy sensing for commercial buildings. Two items are listed: the ER372D LED emergency light battery unit at about $140, and the SENPIR-CM-03 ceiling mounted PIR occupancy sensor at around $44, rated for 120V at 800W, 277V at 1200VA and 347V at 1500VA, cULus listed. Emergency battery units are required by the building code to carry egress lighting for a set duration after power loss, and they need periodic testing to stay compliant. Occupancy sensors are usually specified to meet energy code lighting-control requirements in commercial spaces.
**How long must an emergency light run after a power failure?**
The required duration comes from the building code for your occupancy, commonly 30 minutes or longer for egress lighting. Confirm the requirement for your building type, then select a unit whose rated capacity covers the connected remote heads for that duration.
**Do emergency battery units need testing?**
Yes. Emergency lighting requires scheduled testing and record keeping under the fire code. A monthly function test and an annual full-duration test are typical. Check the requirements applicable to your building.
**What does the multi-voltage rating on the occupancy sensor mean?**
The SENPIR-CM-03 accepts 120V, 277V or 347V supply, with a different maximum load at each. That flexibility means one part number covers residential, US commercial and Canadian 347V commercial installations, but the load limit changes with the voltage.
**Where should a ceiling occupancy sensor be mounted?**
Centrally in the space, with a clear line of sight to the areas people occupy, and away from HVAC diffusers that can trigger false detection. PIR sensors need line of sight and will not see around partitions or into cubicles.
**Can you supply other Etlin-Daniels products?**
Yes. Send the catalogue number to sales@mapleelectricsupply.ca or call (905) 553-7171 and we will check availability and pricing on the wider range.
