The default setting for the switch was that a P-wave(adjustable sensitivity) or the user-set triggers the alarm latch.
Since the p-wave pretrigger adjusts from 1-15, and it isn't too clear (other than 1=max sensitivity/15 least sensitivity) how it needs to be adjusted, and it isn't required, I set it to trigger the unused non-latching relay contact.
I also set it to trigger the alarm and trouble (both) in the event of trouble or exceeding the user set g limit (.15 g, any axis, by code). Since 2 relays trigger simultaneously, it passes the failure-resistance test.
I tested it by slapping it around, and it triggered it at the g level, without the pre-trigger causing a shutdown.
As of this post, the sensor hasn't false-triggered since I set it.
Cheers!

As for your usage request, here's the code:
CCR Title 8, Subchapter 6,Group 3, Article 37:

§3137. Seismic Requirements For Elevators, Escalators and Moving Walks.

Elevators shall comply with the seismic requirements for elevators in Part XXIV of ASME A17.1-1996, except for Rule 2409.1b(1), which is hereby incorporated by reference.

(a) Earthquake protective devices shall be designed, arranged, and maintained to ensure that if any component fails, the elevator will go into the earthquake-sensed mode and be removed from service in the same manner as though an earthquake were occurring, and that the elevator will so remain until the faulty component has been repaired and the system is again arranged to work as intended.

ASME A17.1-1996 Part XXIV Cross reference:
2409.1b Equipment Specifications
(2) Seismic switch shall activate upon excitation in a vertical direction of not more than 0.15 times gravity acceleration (32.2 ft/s 2 ) (9.81 m/s2 ). The frequency response of the switch shall be 1 Hz to 10 Hz.

PS-I find it ironic that there is only a vertical g rating in the ASME A17.1 1996-2005 version of the code, whereas the California code for existing elevators requires all 3 axis.
CCR 3041.d(12) An earthquake sensing device shall activate upon excitation in a horizontal or vertical direction of not more than 0.15 g.
