DS160/DS161 Installation Guide
High Performance Request-to-Exit Sensors

Description

The DS160/161 is a passive-infrared (PIR) detector designed for Request to Exit (REX) interior applications.
The DS160/161 is UL Listed as an access control device under the UL 294 Standard and is listed for Class I for UL Canada under ULC-S319 when it is connected to a UL approved access control system. For C-UL listed installation applications, the REX detector shall be connected to ULC-S319 listed compatible devices (i.e. control units, power supply and locks).
The technology designed into the DS160/161 is based on the principal that all objects emit infrared energy. The warmer an object is, the more infrared energy emitted. Its PIR technology allows the DS160/161 to detect the change in infrared energy that occurs when a person passes through its field of view.
The DS160/161 has features such as Sequential Logic Input (SLI) to eliminate unauthorized entry. SLI allows you to arm the detector using any dry contact device, such as a second detector, card reader, or the access control system. This provides better control for this type of application.
A built-in sounder can be automatically activated if the door is propped open. The sounder can be controlled from any dry contact device. The DS160/161 detection pattern provides dense C-shaped coverage ideal for most REX applications. In addition, complete pattern control allows it to be adjusted to a single zone or placed over a doorknob, for example. There are fifteen possible coverage patterns to accommodate most applications.
This, combined with the ability to monitor the door and intelligently control the lock, adds considerable security to these types of applications.
The DS160/161 uses Motion Analyzer II signal processing to help prevent false activation due to environmental conditions. The relay output consists of two Form “C” contacts that can be adjusted to latch from approximately 0.5 to 64 sec. The latch time features two modes of operation, resettable (where the relay timer will not time out as long as someone is in the field of view) and non-resettable (where the relay will remain latched for a fixed period of time). The relay can also be programmed to fail safe or fail secure in the event of power loss.
The DS160/161 provides one set of relay contacts specially protected from EMF (voltage) spikes caused by connecting to inductive loads.
The DS160/161 may either be ceiling or wall mounted, and its pattern may be aimed and/or masked for more effective use based upon installation needs. It is not designed as a primary means of exit for emergency egress applications.
The DS160/161 is available in a light grey (DS160) or a black (DS161) enclosure along with an optional trim plate (light gray TP160 or black TP161) that can cover a single gang box. Panic hardware must be used with this or any other egress device.

Installation

1. Remove the cover using a small flat blade screwdriver.
2. Rotate the detector clockwise to remove it from the base.
3. Select a mounting location. Before you mount the unit, review Section 6.0 Coverage Patterns on page 6 for more information on the placement and location of the DS160/161.
4. Route the wiring through the base before mounting the base to the wall or ceiling. Refer to Step 5 on page 2 when using the optional trim plate (TP160 or TP161).
5. When using the optional trim plate (TP160 or TP161), run the wiring through the trim plate and into the base before mounting the base and trim plate onto a single gang electrical box. The arrows on the base indicate its correct mounting orientation relative to the door.

Wiring

3.1 Power, Remote Input, Door Contacts, and Tamper
Refer to Table 1 to wire the detector.

Table 1: Terminal Labels and Descriptions

between 12-30 Volts DC or AC.
R| Terminal R is for Sequential Logic Input (SLI), the keycard input or for remote control of the sounder. The contact must be Normally Closed (NC).
Refer to Figure 7 and Section 3.3.5 Sequential Logic Input on page 4 for more information.
D| Terminal D allows the detector to monitor door contacts.
Refer to Sections 3.3.6 and 3.3.7 on page 4 for more information. If used, these contacts must be Normally Closed (NC) door contacts. Do not share these contacts with any alarm systems.
T| Normally Closed (NC) tamper contacts.

Before wiring the unit, review Section 3.3 Wiring Examples on page 2 for more information on the wiring of the DS160/161.
3.2 Contact Output Wiring
The normal settings of the contact outputs change depending on the setting of the Relay Mode Switch (S3). Refer to Section 4.3 Relay Mode (DIP Switch 3) on page 5. 3.3 Wiring Examples
3.3.1 Basic Connection
The basic connection includes the DS160/161, a power supply, and a magnetic lock. When the sensor sees motion, power is removed from the magnetic lock. Relay contacts shown with Switch 3 ON (Failsafe Mode) and Power On. 3.3.2 Spike Protection

• EMF (Voltage) Spike-Protected Relay: Use this relay when connecting inductive loads to the detector. This relay protects the detector from inductive loads that might deliver damaging EMF spikes. No additional spike protection is needed.
• Non-EMF (Voltage) Spike-Protected Relay: This relay is best used for non-inductive loads. When connecting an inductive load that is not spike-protected, such as a magnetic door lock, to the detector, use either a bridge rectifier (such as a KBL01) or a diode (such as a 1N4007). Refer to Figure 10 and Figure 11.

UL listed magnetic locks typically are already EMF spikeprotected, and therefore do not require the bridge rectifier or diode as shown in Figure 10 and Figure 11. Refer to the magnetic lock’s documentation for more information. Failure to spike- protect the detector can shorten the life of the relay contacts.

3.3.3 DS160/161 and a Keycard Reader
Normally, this setup is used when a keycard reader is on one side of the door and the DS160/161 is on the other side. Either swiping a keycard or a motion detected by the DS160/161 removes power from the magnetic lock.
For DIP switch settings, refer to Section 4.7 Remote Input Function (DIP Switches 2, 9, and 10) on page 6. 3.3.4 Direct Sounder Enable
The Direct Sounder Enable setting can be used to activate the DS160/161 sounder from a remote contact. The DS160/161 internal sounder remains on as long as the external contacts remain open. The sounder input can come from devices such as a door controller or door contacts. Turning the sounder on does not affect the relay or relay timer. The direct sounder input does not remove power from the magnetic lock.
Turning the sounder on does not affect the relay or relay timer. The direct sounder input does not remove power from the magnetic lock. To ensure the best sound quality from the sounder, tighten all unused terminals on the terminal strip.
3.3.5 Sequential Logic Input
The detector only activates by motion when the Sequential Logic Input (Terminal R) is open, or for 10 sec after it closes. For example, when a second detector placed before the DS160/161 activates, and for 10 sec after it resets, the DS160/161 activates when it detects motion. Any movement after 10 sec after the contact on Terminal R closes is ignored. For DIP switch settings, refer to Section 4.7 Remote Input Function (DIP Switches 2, 9, and 10) on page 6. 3.3.6 Door Monitor Contacts (First Option)
In the Monitor Door Contacts Mode, a person entering the field of view of the detector activates the relay and timer. Door contacts connected to Terminal D monitor if the door is open or closed. If the door is held open and the relay timer is in the last 10 seconds of the latch time, the sounder will turn on. In order for this to work correctly, the latch time must be set for 16 seconds or greater (refer to section 4.3 on page 5.) The sounder also activates if the door is opened without first activating the detector or keycard input. The sounder remains on until the door closes or by someone moving in the field of view.
For DIP switch settings, refer to Section 4.7 Remote Input Function (DIP Switches 2, 9, and 10) on page 6. To ensure the best sound quality from the sounder, tighten all unused terminals on the terminal strip.

3.3.7 Door Monitor Contacts (Second Option)
If the detector is activated but the door is not opened, the relay drops out after 10 sec. If the detector is activated and the door opens, then closes, the relay drops out after 2 sec. This prevents unauthorized people from entering.
In this mode, the REX can be activated by either someone walking in its field of view or from a remote device if using the R input. If using the R input to activate the detector, switch 2 should be set in the ON position (resettable mode).
For DIP switch settings, refer to Section 4.7 Remote Input Function (DIP Switches 2, 9, and 10) on page 6. 3.3.8 Disabling the Request-to-Exit
The DS160/161 can be disabled by using Terminal R and an external device such as an access control or burglar alarm system. When the contact connected to Terminal R closes, the DS160/161 disables after a 10-sec delay. The DS160/161 returns to normal operation as described in Section 3.3.5 Sequential Logic Input, on page 4, after the contact closes. The NFPA 101 Life Safety Code requires secured doors to have a “manual release device that shall result in direct interruption of power to the lock – independent of the access control system electronics”.

Switch Settings

You can change the switch settings by sliding the switch to the ON or OFF position. Refer to Figure 18. 4.1 LED Operation (DIP Switch 1)

• ON: LED operates normally when motion is detected.
• OFF: LED is turned off.

When LED is enabled, it will flash on and off when first powered up. Once the flashing LED stops, the REX is ready to be used.
4.2 Timer Reset Mode (DIP Switch 2)

• ON: The relay timer starts when the detector sees motion and restarts if there is additional motion. The relay only drops out when there is no more motion and the timer expires.
• OFF: The relay timer starts when the detector sees motion. It drops out when the timer runs out, even if the motion continues. If the motion continues, the timer restarts.

Refer to Section 4.3 Relay Mode (DIP Switch 3) to select the time period.
4.3 Relay Mode (DIP Switch 3)

• ON: The relays operate in the Fail Safe Mode. Refer to Section 3.2 Contact Output Wiring, on page 2, for more information.
• OFF: The relays operate in the Fail Secure Mode. In the secure mode, the REX shall be installed in a manner that does not impair the intended operation of panic hardware used in conjunction with the REX detector. The Fail Secure Mode must be authorized by your Local Authority Having Jurisdiction (AHJ). Refer to Section 3.2 Contact Output Wiring, on page 2, for more information.

4.4 Relay Timer (DIP Switches 4, 5, and 6)
Setting Switches 4, 5, and 6 determines the amount of time the output relays energize (between 0.5 sec and 64 sec) when motion is detected. Refer to Table 2 to set the relay timer.

Table 2: Relay Timer DIP Switch Settings

4.5 Signal Processing (DIP Switch 7)
The Signal Processing setting determines how sensitive to movement the detector is.

• ON: High sensitivity (REX Mode)
• OFF: Low sensitivity (security sensor)

4.6 Door Secure Mode (DIP Switches 8, 9, and 10)
If the detector activates, but the door does not open, the relay drops out after 10 sec. If the detector activates and the door opens and then closes, the relay drops out after 2 sec. This prevents unauthorized people from entering.
To ensure that the Door Secure Mode operates as expected, set the relay timer (DIP Switches 4, 5, and 6) to 16 sec or longer.

• ON: If DIP Switches 8, 9, and 10 are all ON, Door Secure Mode is enabled. Wire according to the wiring example shown in Section 3.3.7 Door Monitor Contacts (Second Option) on page 4 for door secure.
• OFF: If DIP Switches 8, 9, and 10 are all OFF, Door Secure Mode is disabled.

4.7 Remote Input Function (DIP Switches 2, 9, and 10)
The Remote Input Function switches determine what the DS160/161 does when the contact attached to Terminal R is closed.

• Keycard Input: An input to the Terminal R activates the detector.
  Normally, this is used with a keycard reader outside of the door/building. The internal sounder does not activate when the keycard input is selected. The keycard inputs are affected by Resettable/Non-resettable Mode (Switch 2). The relay remains activated for as long as the keycard input is closed. The timer starts when the keycard input is force activated. If Switch 2 is on, toggling the keycard input again restarts the timer ( the suggested setting). When Switch 2 is off, toggling the keycard input does not restart the timer.

• Direct Sounder Enabled: The sounder is turned on for long as the contact on Terminal R is open. It does not affect the relay or timer.

• Sequential Logic Input: The detector only activates if the Sequential Logic Input (Terminal R) is open, or for 10 sec after it closes again. Movement after 10 sec after the contact on Terminal R closes is ignored.

• Monitor Door Contacts: Door contacts connected to Terminal D monitor if the door is open or closed. If the detector activates and the door is open when 10 sec remain on the timer, the sounder turns on. If the door opens without activating the detector, the sounder turns on. The sounder remains on until the door closes or the detector activates. For this feature to work, set the timer a minimum of 16 sec.

Refer to Table 3 to set the remote input function.
Table 3: Remote Input Function DIP Switch Settings

Complete the Installation

1. Secure the detector inside the base.
2. Adjust the sounder volume. To ensure the best sound quality from the sounder, tighten all unused terminals on the terminal strip.
3. Replace the cover and secure with a screw. Use a drill to remove a screw knockout in the cover only, then start screw and tighten to secure.

Coverage Patterns

The coverage (detection area) of the DS160/161 varies depending on the mounting height above the floor, angle of the lens, and if the unit is mounted on a wall above the door or on the ceiling.
The unit can also be masked to allow only some parts of the coverage pattern to be active.
6.1 Examples
When the unit is mounted on the wall and the lens is pointed straight down, some detection zones point toward the wall and do not detect movement. The higher the unit is mounted, the larger the coverage area. Do not mount the DS160/161 more than 15 ft (4.6 m) above the floor. When the DS160/161 is mounted on the wall above the door, you can move the coverage pattern away from the wall by rotating the detector’s lens.

6.2 Masking
The DS160/161 is supplied with three masking wedges used to disable any part of the coverage pattern. Each wedge covers approximately 25% of the coverage pattern.![BOSCH DS160 DS161 High Performance Request to Exit Sensors

• Masking Options](https://manuals.plus/wp-content/uploads/2023/08/BOSCH- DS160-DS161-High-Performance-Request-to-Exit-Sensors-Masking- Options.jpg)Insert a masking wedge by placing the bottom peg in first. Then press on the center of the wedge until it snaps into place. Remove a wedge by placing the tip of a small screwdriver behind the wedge and prying it up. Do not scratch the lens when removing the wedge. Up to three masking wedges can be used if you only want to detect in a very small area, such as around a doorknob or crash bar. The coverage pattern depends on how high the DS160/161 is mounted, location of the unit and the position of the detector lens. If you want a setup as shown above, mount the DS160/161 just above the door, on the hinge side, with the lens pointed down and  slightly out.
