Pulsing a PGM in a DSC 1832 with a Holdup button

[ECMA]

I am trying to send a video clip using an OZ Vision box and the PGM Outputs of the PC1832 for any of these events:
- Arm/Disarm -> PGM Out (17)
- Burglar alarm -> Zone Definition : (03)Instant - PGM Out: (01)
- HU Button -> Zone Definition : (12) 24hr Hold-Up -PGM Out (??)
Using the PGM outputs of my PC1832 and external relays and I am inputing these signals into the Alarm In terminals of the OZ Vision.
So far I have been able to switch the relays for the first two events, but I do not know how to pulse the relay using my third event.
Any ideas?
Thanks

I found the answer. What you need to do in order for your Hold-Up button to activate any of your PGMs without sounding the bell and deactivate your PGM when it is restored :

1 - Define what your panic zone is - Lets say Zone 8
2- Zone Definition for zone 8 is : (12) 24hr Hold-Up
3- Decide what PGM to use. Lets say PGM1. Then define your PGM Output Option as (29). 009=(29)
4- On your PGM Attributes 501 - turn on the number corresponding to your HU zone, ie: 8
