Tx is LED On timer. 
Factory default is 6.6 second.

Tx = 24,576 x R20 (Ω) x C7 (F)
= 24,576 x 15,000 x 18 nF x 10-9
= 6.6 second


Ti is inhibit movement after LED Off timer. 
Factory default is 4.8 second.

Ti = 24 x R8 (Ω) x C8 (F)
= 24 x 2,000,000 x 100 nF x 10-9
= 4.8 second


Modified

This item connect Pin 1 to V+ So it already config as retriggerable.

Next modified R20 to 407K.

Tx = 24,576 x R20 (Ω) x C7 (F)
= 24,576 x 475,000 x 18 nF x 10-9
= 210 second


Next modified R8 to 2M + 100K in parallel.

Ti = 24 x R8 (Ω) x C8 (F)
= 27 x 95,238 x 100 nF x 10-9
= 0.25 second
