For High-Rise test:
Disconnect phone line to the CAB at the EMCS. Try
calling the cab for quick test to verify alarm.
Reconnect to reset then repeat but wait for alarm.

About the EMC-ALRM Phone Line Monitoring
Alarm Board
Key Features:
 Complies with ANSI A17.1/CSA B44 Safety Code for Elevators
 The EMC-60 Emergency Hands-free Elevator Phone, combined with the EMCS
Emergency Phone Consolidator, if applicable, verifies the operability of the
telephone line and signals the EMC-ALRM if the line is not functional.
 In the event of a phone line failure, the EMC-ALRM activates an audible and
illuminated visual signal for each group of elevators.
 The key-switch or pushbutton, accessible only to authorized personnel, will
silence the audible signal for no less than 12 hours.
 The EMC-60/EMCS monitors the failed phone line repeatedly and will signal the
EMC-ALRM to cancel the alarm immediately.
 The illuminated visual signal will extinguish and the system return to normal.
Battery backed-up power is recommended to enable notification of elevator
communications failure in the event of power failure (built-in when using an EMCS or
EMC-PAC).

Description of Operation
The Phone Line Monitoring (PLM) feature built into the EmerCom EMC-60 Hands-free
Elevator Phone monitors the phone line as required by ASME A17.1/CSA B44 Code. If
the phone line fails a pair of contacts in the EMC-60 will open (fail-safe) to signal the
EMC-ALRM Alarm Annunciator to generate an audible & visual alert in the elevator
lobby, in the vicinity of the Firefighters Recall Switch.
The visual alert LED will flash until the phone line becomes operational again but the
audible alert buzzer can be silenced by authorized personnel with the key switch (or
pushbutton accessible only to authorized personnel). The buzzer will remain silenced
for 12 hours unless the phone line is restored earlier.
Three LEDs mounted on the EMC-ALRM PCB indicate ‘normal’, ‘alarm’ or ‘silenced’
status.
A PLM test feature is available in the EMC-60 phone to simulate an alarm by opening
the relay contacts for the number of seconds entered (Command # 24), after which it
returns to normal. An extended test can be conducted by moving the test switch on the
EMC-ALRM PCB into the “TEST” position.
For High-Rise installations an EMCS Consolidator or Rescue Station will be required to
call into any cab from an on-site location. The EMCS Consolidator regularly checks the
health of the external phone lines and the connection with all of the EMC-60 Phones
and sends a signal to the EMC-ALRM (connections to the EMC-60 phone PLM
terminals are not required with the EMCS).
Troubleshooting
EC-Phone indicates a phone line fault but no alarm triggered
 Check 12-24V DC supplied and polarity correct
 Ensure additional EMC-60 phones are connected in series
EC-Phone indicates phone line okay but alarm triggers
 Verify the test switch is in the “NORMAL” position
 Check wiring for open-circuits.
Buzzer is not loud enough
 Ensure the sticker has been removed from the buzzer

 Problem or fault description
 Name of the person requesting the RMA, phone number and shipping address
Please reference the RMA number clearly on all packaging and paperwork.
Note: Statistically, more field problems are caused by wiring, connection, power supply or
installation issues rather than the devices themselves. Please have your field staff call us from
site before concluding that an EmerCom product needs to be returned, to offer you the
