Otis Elevator Emergency Lighting RY-EM01 – Installation, Testing & Replacement Guide
Nanjing Zhuye Elevator Parts – OEM stock, global shipping, 24/7 support
Nanjing Zhuye Elevator Parts – OEM stock, global shipping, 24/7 support
The RY-EM01 is the UL-listed emergency lighting unit that keeps every Otis Gen2® and SkyRise® cab illuminated during mains failure. Housed in a 200 mm × 150 mm × 45 mm IP30 ABS enclosure, the device switches to battery power within 0.2 s, delivers 3 W of LED light for 3 hours and still has spare terminals for the alarm buzzer. A single flat battery or a blown LED strip will trigger a “90” fault and fail the annual fire inspection. Nanjing Zhuye Elevator Parts keeps hundreds of factory-charged RY-EM01 units in Rotterdam and Nanjing so you can restore full emergency lighting the same day. Below is an 800-word field manual that explains correct usage, monthly testing and the replacement cycle that keeps your elevators safe, compliant and passenger-friendly.

3. Installation – 15 minutes if you mark the wires
Safety: place the car on inspection, open the main disconnect and verify 0 V on the 24 Vdc rail.
-
Mark the old unit wires – note 24 Vdc input, LED output, buzzer.
-
Remove two TX10 screws; lower the unit onto a rag (LED is fragile).
-
Clean the mounting surface with IPA; check for cracks >1 mm.
-
Mount new RY-EM01; torque screws to 1.5 N·m.
-
Connect 24 Vdc (brown +, blue -) and LED plug (white connector).
-
Apply power – green LED steady; battery voltage 3.7 V ±0.1 V.
-
Press TEST button – LED illuminates, green LED flashes every 2 s.
-
Measure illuminance: >30 lx at floor level, >1 lx at 1 m height.
-
Record serial number, date and test time in CMMS.
4. Functional test – prove it to the inspector
a) Change-over time: <0.2 s from mains fail to LED on.
b) Illuminance: >30 lx at floor level, >1 lx at 1 m height.
c) Battery voltage: 3.7 V ±0.1 V after 1 h charge.
d) Duration: >3 hours at 3 W load.
e) Export OST test report and attach PDF to site file.
b) Illuminance: >30 lx at floor level, >1 lx at 1 m height.
c) Battery voltage: 3.7 V ±0.1 V after 1 h charge.
d) Duration: >3 hours at 3 W load.
e) Export OST test report and attach PDF to site file.
5. Preventive maintenance schedule
-
Monthly – press TEST button; LED must illuminate and green LED flash.
-
Quarterly – measure battery voltage; replace if <3.5 V.
-
Annually – run 3-hour discharge test; illuminance must remain >1 lx.
-
Every two years – replace the Li-ion battery – capacity drops to 70 % after 500 cycles.
6. Replacement cycle – usage and temperature decide
Manufacturer specification: 4 years. Nanjing Zhuye analytics refine this:
-
Light duty (<150 starts/day, office): 5 years
-
Standard duty (150–400 starts, residential): 4 years
-
High temperature (>35 °C, rooftop): 3 years – battery life halves every 10 °C rise.
Replace immediately if:
-
LED does not illuminate on TEST – battery flat or PCB fault
-
Change-over time >0.5 s – relay contacts oxidised
-
Illuminance <1 lx – LED degradation or lens yellowing
-
Battery swelling – risk of electrolyte leak
7. Eco-disposal & warranty
Return the old unit in the prepaid box; Nanjing Zhuye recovers Li-ion, ABS and copper and issues a €5 recycling credit. Every RY-EM01 ships with a 24-month replacement warranty, extendable to 48 months when you join our annual battery-replacement program.
