Honeywell Security Terms and Best Practices

Arm Away – Alarm system armed with no persons inside the protected area. Pets OK if all motions are pet immune.

Arm Stay – Alarm system armed with people inside the protected area. All motions will be ignored.

Arm Instant – Alarm armed without exit delay countdown.

Arm Max – Alarm system armed with no entry delay. Do not recommend this to users. It can easily result in false alarms.

Exit Delay – The period of time after arming in which someone can leave through a designated exit door before the alarm system goes active. Usually, 60 seconds is preferred.

Entry Delay – The period of time after someone enters a protected area through a designated entry door before the alarm activates. Usually, 30 seconds is preferred.

Interior Follower – This refers to an interior motion sensor. Not active in a STAY mode. It can also be used for an interior zone a user may wish to not have active if they stay in the home when the system is armed in a STAY condition.

Auto Stay – If an alarm panel is programmed with Auto Stay enabled, the system will default to an Arm Stay condition if an exit door is not tripped after arming the panel in an Arm Away mode. Essentially, if you arm the system as if you are leaving and you do not leave, the panel assumes you are still in the protected area, it, therefore, switches to a Stay mode to avoid motion sensor alarm activation. It is critical these feature not be enabled when using keyfobs or mobile apps to activate the alarm system. If you are outside and arm your system (in AWAY mode) with a keyfob, you do not want the alarm system to revert to a STAY mode because you did not open a door to leave. After all, you are already outside the protected area

Partition - A partition is an area protected by a group of sensors. A Vista 20P can have 1 or 2 partitions and even 3 in a common lobby configuration (see common lobby). When using 2 partitions, each partition can be armed or disarmed independently. Each partition must have its own keypad.
In most cases, 2 partitions are used for House/Garage scenarios where the client may wish to arm the garage at night, but not the house.
There is only one bell output on a Vista 20p so any alarm event will be heard wherever there is a siren. Through the use of relays and Advanced Programming, it is possible to separate sirens to be partition specific but there are limitations.

Common Lobby - A common lobby is a shared area by two or more separate protected areas or partitions. 
Consider two businesses that share a lobby with restroom, parking area or elevator. In the morning, business 1 staff enters and disarms their business alarm system via a keypad in the shared or “lobby” area. This disarms the common lobby area as well as their business area, however business 2 area remains secured and protected. That evening, business 1 staff closes and head home. They arm their alarm system with a keypad inside their business. The common lobby cannot be secured because business 2 is still open.  Later, when business 2 closes they arm their alarm system from the keypad in the lobby area. Because both business partitions are now secure, the lobby now also becomes a secure, third, area.

When using a common lobby you must install one keypad for each partition, including the common lobby. There are methods by which you could get by with 1 keypad in the lobby area, but it is FAR simpler to instruct users if each area has its own keypad.

A Vista 20P can have one or two partitions with a common lobby option. Setting the Vista 20P for 3 partitions automatically creates a common lobby configuration. If you need more partitions you must move up to a Vista 128 panel.
