BPT video entry phone

[branco]

Hi guys,
I have installed and partly tested a BPT video entry phone.
I'm using 1 IT300, 1 VA/01, 2 VA/100, 3 DMVC/01 and 7 NS/61.
Only 1 maglock to control. Wich has been put through a relay getting signal from DMVC/01.
i have been asked to add a request to exit button. after a quick look at the buttons and connections,
it seems to me they might need a relay to work. is it true?
thanks for your help

No break the circuit to the mag lock, eg nc exit button wired into the neg supply to the mag,
