Description
This unit is ideal for applications requiring precise timing functions, such as access control and security operations. It features a delayed egress functionality that can be set to release a door from 1 to 60 seconds. Suitable uses include daily or weekly test modes, one-shot timers, door prop alarms, timed door annunciations, cut-off timers, and alarm swing eliminators. The digital display enhances user-friendly programming and offers real-time monitoring.
With an input range of 12 to 24 volts AC or DC, the unit operates with relay triggers through dry contacts. The dry form “C” contacts are rated at 2A/120VAC/28VDC. It has a current draw of 15mA in standby and 30mA when the relay is energized. The straightforward programming includes a one-shot feature that provides programmable relay activation at either the start or end of the timing cycle.
Features include:
– Delayed Pulse Mode: A 1 to 60-second programmable pulse at the end of the timing cycle.
– Delay Mode: The relay can be programmed to energize or de-energize during the timing cycle, adjustable from 1 second to 24 hours digitally.
Equipped with EE Prom memory, this unit prevents loss of programmed settings during power failures. Visual indicators via the LCD screen provide real-time countdown information. It operates within temperatures of -20ºC to 49ºC (-4ºF to 120ºF) and can be stored in conditions ranging from -25ºC to 70ºC (-13ºF to 158ºF) with a relative humidity of 85% +/- 5%.
