Q

What is a relay input ?

A

A relay input is the part of a relay’s frame that connects to the control component. The input circuit activates when a voltage higher than the relay’s specified pickup voltage is applied to the input.

Q

what is a head end system ?

A

Head end systems are systems that collect measurement data and meter events for eventual submission to the application. Many devices can communicate to the application through a single head-end system, but a utility may have numerous head-end systems through which they communicate with devices.

Q

What type of pathway is required for signal/data elevator escalator circuits ?

A

class X

24
Q

When is isolation required for elevator escalator signal/ data circuits ?

A

isolation is required between each element

25
Q

When are class B circuits allowed in signal/data circuits?

A

When they are dedicated to specific elevators and bank of escalators

26
Q

What type of pathway is required for notification circuits ?

A

Class B

27
Q

What type of Pathway is required for Auxiliary/Controls circuits ?

A

Class B

28
Q

What is each escalator solenoid release circuit required to have ?

A

a class B pathway

29
Q

What level of Pathway survivability id required for a fire alarm circuit for elevator/escalator ?

A

NONE

30
Q

What three things will elevator controls contain ?

A

primary recall, alternative recall, and cab signaling

31
Q

What is primary recall ?

A

An elevator recall happens when the fire alarm system activates and sends the elevator cab and its occupants to the primary floor.

32
Q

What is alternate recall ?

A

An alternate recall is a secondary floor of egress that can be used if the primary level becomes unsafe for egress. The alternate recall level is typically the second floor, which is an alternate designated level other than the main floor.

33
Q

What is cab signaling ?

A

signals provided by the elevator in case of an emergency

34
Q

IF the required elevator functions are not included what must be done ?

A

They must be available to be included at a latter date

35
Q

What type of protection is required for existing non power limited elevator or escalator control circuits an voltage should this circuit be ?

A

interposing relay protection is required and 24VDC

36
Q

What is an interposing relay ?

A

an auxiliary relay that is used to isolate two different systems or devices from one another.

37
Q

What type of detector is required for an elevator room ?

A

smoke detector

38
Q

Under what conditions are fire alarm conduits within elevator shaft and escalator truss areas allowed to be repurposed ?

A

If they are undamaged

39
Q

What must occur if fire alarm conduits within elevator shaft and escalator truss areas are allowed to be repurposed ?

A

The installation must be coordinated to minimize down time.

40
Q

what type of detection is required within enclosed lobby areas and shafts ?

A

smoke detectors

41
Q

What must be constant if a conduit in an elevator shaft/ escalator truss is repurposed ?

A

the spacing of the devices must be consistent

42
Q

What type detector is required for shaft ways mezzanines and platforms that are open to outer air?

A

WATER PROOF conventional heat detectors

43
Q

what is a shaft way ?

A

The vertical space in a building in which the elevator or lift travels.

44
Q

interface modules are required for

A

escalator sprinkler monitoring

45
Q

what three things are included in escalator sprinkler monitoring ?

A

tamper switch monitoring at feed/backflow assembly and all drain lines, sprinkler heat trace panel monitoring, supervisory air monitoring, and waterflow condition

46
Q

What is a feed/backflow assembly ?

A

a device that works to protect potable water from contamination or pollution due to backflow

47
Q

What is a heat trace ?

A

A heat trace system is an electrical system used to maintain or raise the temperature of pipes and vessels

48
Q

Escalator solenoid release is required , how is it performed ?

A

utilizing an addressable relay with fail safe operation to an interposing relay that controls the 120VAC to the solenoid valve.

49
Q

Ventilation and what controls are required for elevator/ Escalator FA systems ?

A

Ventilation and damper controls

50
Q

How are Ventilation damper controls controlled ?

A

controlled through an addressable module that supervises the 24VDC to an interposing relay and an additional module that supervises the 24VDC riser.

51
Q

What type of operations are required to have mechanisms to verify alarms associated with escalator operations ?

A

escalator operations.

52
Q

all smoke detectors related to escalator and elevator protection shall be what ?

A

EMR smoke detectors

53
Q

What is an EMR smoke detector?

A

The EMR Series holder/release device incorporates a photoelectric detector and can control the spread of smoke and fire in a specific location or throughout the building if wired into a central alarm panel.

54
Q

What should be placed 30 feet on both sides of an escalators balustrade ?

A

smoke detectors

55
Q

A notification device should be provided in each _______ connected to the station fire alarm system.
