Frequently Asked Questions - SEG-155 Steren
How do I reset the Steren SEG-155 to factory defaults?
Press and hold the Reset button (located on the back panel) for 5 seconds until you hear a long beep. All user settings and sensor pairings will be erased.
Can I add additional sensors to the system?
Yes, the SEG-155 supports up to 4 zones. You can purchase compatible 433.92 MHz sensors and pair them by entering programming mode (press Arm + Stay keys together).
How do I change the backup battery?
Open the battery compartment on the back of the main unit. Replace the built-in 3.6V Ni-MH rechargeable battery with an equivalent type. Dispose of old batteries properly.
What does the 'Stay' mode do?
Stay mode arms the perimeter sensors (door/window) while disabling interior motion detectors, allowing you to move inside the house while the alarm is active. Press the Stay button on the keypad or remote.
How do I silence a false alarm?
Enter your 4-digit PIN on the keypad and press Disarm. Alternatively, press the Disarm button on the remote control. The alarm will stop immediately.
What is the maximum communication range between sensors and the main unit?
In open space, the range is up to 100 meters. Walls and obstacles reduce this distance. Ensure sensors are within range; test after installation.
Can I adjust the entry delay time?
Yes, enter programming mode (press Arm and # keys), then select menu option for Entry Delay. You can set delays from 0 to 60 seconds. Confirm with #.
How do I test if my sensors are working correctly?
Activate Test mode by pressing the Test button on the keypad (if available) or trigger each sensor. The main unit will beep or display the zone number. If no response, check battery and pairing.
What should I do if the keypad displays 'Low Battery'?
Replace the backup battery in the main unit as soon as possible. The system will continue to work on AC power, but backup protection will be lost until the battery is replaced.
Does the SEG-155 support remote monitoring via phone?
Yes, it has an auto-dialer that can call up to 3 pre-programmed numbers when an alarm occurs. You need a landline phone connection. The system will play a recorded message.
