Name the three most commonly used credential types.
Magstrip, Fingerprint, Proximity
What jack is used to seize the phone line attached to the dialer of a security system when an alarm is activated?
When installing a glass break detector to monitor plexiglass, what type of detector should NOT be used?
Glass break - must use shock sensor.
What is the difference between a "duress code" and a "hold up alarm"?
Duress Code: Special signal with no siren or alarm. Most turn off at panel.
Hold up alarm: Button under a desk or foot level
Explain where the resistor is placed for both an open loop and closed loop door contact.
Open loop - parallel
Closed loop - Series E.O.L.
An earthquake is a potential cause for what kind of frequency that may cause problems for a security system?
Shock sensor - Seismic
What makes an access control system so beneficial and effective?
Restricts access without altercation, less expensive since you just change codes instead of all the locks, always know who's in the building.

N/O Closed loop - most common
N/C Open loop
Where must a smoke detector be placed in an elevator lobby?
Within 21' of the center
Explain the difference between a control module and a relay module used in fire alarm systems.
Supervised and unsupervised
Control Module: To be activated, either manually or through panel programming, on a select zone or area of coverage basis.
Relay Module: Allows the dry contact to be activated, either manually or through panel programming, on a select basis.
When installing a smoke/heat detector on a wall, the top of the device shall be how far from the ceiling? Why?
4-12". Smoke "curves"
What device is used for two-way communication to the FCC?
fire phone FFT
Duct smoke detectors are permitted to generate what two types of signals?
Alarm and supervisory
What is the main difference between a Central Station and a Proprietary Supervising Station?
Central: controlled and operated by a person, firm, or corporation done outside of the site.
Proprietary: "Same premises" Owned by a company and supervising station personnel in attendance at all times take action in response to signals
