Control shall be capable of receiving ac

30、tivation signals from any device with normally open dry contact output. 1. With push-to-operate function enabled, the control shall provide a means of initiating a self-start activation circuit by slightly pushing the door open at any point in the door swing. 2. Latch Assist shall provide a two seco

31、nd impulse in the close direction to overcome restrictions with locking devices of pressure differentials, allowing the unit to operate in standard time delay mode, and permitting the door to close from the full open position after the hold time is satisfied.
