8.6.4.15: Car Emergency System
Procedure Note
Check the condition of all buttons, switches and
visual indicators.
Replace any faulty components, as
required.
Two-way communication:
Place a call on the two-way communication
device and ensure the call is responded to
correctly, i.e., the call goes to a location staffed
by personnel authorized to take appropriate
action in an emergency situation.
If the call is not acknowledged within 45
seconds the call must be forwarded to an
alternate location.
Remote/local alarm system (e.g. KRMS, if
applicable):
• Press the voice connection button in the car.
• Wait for a connection, and then perform a test
connection to the call center.
• Verify disconnection of the device following
deactivation of the call by the call center.
• Verify that the connection automatically
disconnects 20 seconds after initial voice
notification if caller does not extend call.
Emergency stop switch:
Check to ensure the elevator stops promptly
when the stop button/switch is activated. Check
the condition and functionality of the device.
Replace the emergency stop switch if it is
damaged or the markings are illegible.
Audible Alarm:
Where the Alarm Button is localized inside the
car, on top of the car or under the car, check
operation of the audible alarm to ensure it can be
heard outside the hoistway.
Ventilation system:
Examine and maintain the car ventilation system.
• Ensure the fan is properly guarded and
securely fastened.
• Clean the fan annually and lubricate the motor
bearings with 30w motor oil (not applicable
with sealed bearings).
Emergency power:
Disconnect normal power and check to ensure
the emergency light, audible alarm and two-way
communication means operate properly on
battery power.
• Use a voltmeter to verify output of the
battery.
• The emergency power system must have
the capacity to power the illumination and
two-way communication means for 4
hours, and the audible alarm for 1 hour.
