SECO-LARM ENFORCER SA-025Q User Manual

Multi-Purpose
Programmable Timer
SA-025Q
Installation Manual
The SA-025Q Programmable Timer Module is suitable for a wide range of timed security and
access control operations. Auto-sensing of input voltage and DIP switches for programming make
installation easy.
 Timer can be set from 1 second to 60 minutes
 Can be triggered via an N.O. positive (+) trigger input signal or an N.C. negative (-) trigger
device or by powering up the unit
 Relay can be programmed to activate at the start or at the end of the timing cycle
 Relay can also be set to activate for one second at the end of the timing cycle
 Relay can be programmed to pulse (flash) or be steady on
 Built-in reset function to manually reset timing cycle
 Form-C relay, contact rated 10A@24VDC/250VAC
 LED indicates relay is energized
 12~24VDC operation (auto sensing)
 Current draw – Less than 1mA (standby) or 40mA (relay energized)
 Functions programmed via DIP switches – no jumpers to cut
