(2) Disabling the signal jammer Deus Ex: HR Guide
Last update: 11 May 2016
Note! Disabling the signal jammer is optional and you should treat this objective as a possibility to gain additional experience points. You do not have to search around for kidnapped scientists, because this step is described in further part of this guide. But if you want to focus only on getting to scientists, just scroll down to the description of Step 3 (Finding Declan Faherty).
Map legend: 1 - Main entrance to the security building; 2 - Rear entrance to the security building (through the window); 3 - Terminal controlling the jammer; 4 - Armory.
The jammer can be disabled in two main ways. A first option is to get into the security building. This object is located east from the main square (you can follow signs Security and Armory). If you want to choose a main entrance to the building, then after reaching the main square head north-east #1. If you didn't stun guards there, you have to watch out for them now, skillfully hiding behind covers. The same applies to a defensive turret north from here. Go to the small, eastern balcony, and you'll reach the main entrance to the security building #2.
An alternative way to get inside the security building is to use one of the windows. To do so, return to the start area, specifically to an alley where you've met first two guards. Now head north until you reach a fence with a big hole in it #1. You have to move a container blocking your way, using the Move/Throw Heavy Objects augmentation. Go further north, reaching a place where you can safely open the shutter #2.
There are two guards inside the security building and it would be good to stun then. If you prefer peaceful solutions, wait until they split up. I suggest starting with a guard, who patrols a main corridor #1, and then eliminate his buddy sitting on chair in the main room #2. If you prefer force solutions, then shoot your opponents before they split up and watch the main door in case anyone else approaches here.
I suggest starting exploration of the security building with a central storage room, where one of the guards kept returning to. In addition to lockers, you'll find there a PDA #1 with a code 0111. Now you can go to the southern room, where second guard was staying and head towards not yet explored, western door #2.
You'll find yourself in the main security room, where two computer terminals are located. First of all use this one, which has no security lock #2 - thanks to his you'll be able to disable one of the security cameras here #2.
The most important thing is to interact with a terminal controlling the jammer #1. It has second security level lock, but you can also use a code 0111. After logging into the system, confirm that you want to switch it off #2. After few moments Pritchard will contact you and give you exact coordinates of three scientists (unfortunately Megan Reed is not among them).
Reward: 250 experience points + 750 experience points for remaining unnoticed.
It would be good to take this opportunity and explore the entire security building. To the north you'll find an armory #1, which has a fifth security level lock. In addition to ammo and weapons you'll find also a weapon upgrade there #2.
There are also two barracks in the northern part of the security building. The left door has fourth security level electronic lock but you can also use a code 1385. Inside this room you'll find Typhoon ammo and a weapon upgrade among other things. The right door has the same security level lock as the left door - you would start in this room, if you would have chosen a way through the shutter #2.
Another way to complete this objective is to get to the terminal near the jammer. A jammer itself is located in the southwestern part of the main square #1 and you can get into this fenced area in several different ways. The easiest one is to jump over the fence #2, but you would need the Jump Enhancement augmentation.
If you can jump or you don't want to, then head west #1, watching out for a security camera which is located on the northern building wall. You might use a camouflage here (the Glass-Shield Cloaking System augmentation) and walk through the laser barrier #2. I do not recommend using a terminal to "play" with the barrier, because it has third security level lock.
Regardless of how you get inside the fenced area, you have to watch out for a single guard patrolling this area. It would be best to stun him, but if you prefer force solutions, he is probably dead by now. In such situation you do not have to worry about getting near the jammer, because it is enough to cross the laser barrier and ignore the alarm sound.
Now look for a ladder #1 which leads to the upper control panel. Interact with the terminal controlling the jammer #2. It has second security level lock, but you can use a code 0111. Confirm that you want to switch it off #2. After few moments Pritchard will contact you and give you exact coordinates of three scientists (unfortunately Megan Reed is not among them).
Reward: 250 experience points + 750 experience points for remaining unnoticed.
