1.3.2 Mode-2

In MODE-2 (switch 1 ON), the monitor relay is typically connected to a local alarm (bell, buzzer, light,

etc.) and the alarm relay is typically connected to the buildings alarm system. In this mode, there are

two distinct conditions under which the tracker board will respond to a door ajar condition; FORCED

CONDITION and PROPER CONDITION.

FORCED CONDITION - The access system or request to exit device has not activated the door strike

(output relay not activated) but the door ajar contact (door ajar switch closes) indicates that the door

has been opened. In a forced condition, both the monitor relay and alarm relay will activate whenever

the door ajar switch is closed, and will deactivate when the door ajar switch opens. Note that a forced

condition can only occur if the access system or request to exit device has not activated the door

strike, otherwise a proper condition occurs.

PROPER CONDITION - The access system or request to exit device has activated the door strike

(output relay activated), but the door has not closed (door ajar switch closed) by the end of the strike

time. In a proper condition, the monitor relay will go on and off at 1-second intervals until the door

closes (door ajar switch opens), or until the door ajar timer (switches 5 & 6) runs out. Five seconds

prior to the door ajar timer running out, the monitor relay will stay on, and then deactivate. When the

door ajar timer runs out, the alarm relay may or may not activate depending on the setting of switches

3 & 4. If the alarm relay does activate (switches 3 & 4 off), it will remain activated until the door closes

(door ajar switch opens).

(see chart on next page).
