Bosch DS150I, DS151I Installation Manual

DS150i/DS151i Installation Guide Request-to-Exit PIR Detectors

1.0 Description

The DS150i is a passive-infrared detector designed for request to exit (REX) applications. It is UL Listed as an access control device under the UL 294 standard and is listed for Class I for UL Canada (ULC-S319). For C-UL listed installation applications, the REX shall be connected to ULCS319 listed compatible devices (i.e. control units, power supply and locks). Intended for indoor use only.

The relay output consists of two Form "C" contacts that can be adjusted to latch from approximately 0.5 sec to 64 sec. The latch time features two modes of operation: resettable (R) and non-resettable (NR). The relay can also be programmed to fail safe or fail secure during a power loss.

You can mount the DS150i on the ceiling or wall and aim and/or mask its pattern for more effective use based on installation needs. The DS150i is not designed as the primary means of exit for emergency egress applications.

The DS150i is available in a light grey (DS150i) or a black (DS151i) enclosure. An optional trimplate is also available in light grey (TP160) and black (TP161).

2.0 Mounting

1. Select a mounting location over the center of the door or doors to be covered. The target must walk directly toward the detector. Mount the detector on the ceiling, wall, or door frame. The detector can be surface mounted or mounted to a keyswitch plate with a "D" size hole.

The DS150i is not tall enough to completely cover a single gang box. Where aesthetics are important, mount it using the optional trimplate (TP160 or TP161). Refer to Figure 1

Figure 1: Optional Trimplate

for additional instructions for mounting with the trimplate.

3.0 Wiring

3.1 General Information

Only apply power after all connections are made and inspected. Remove all system power (AC and standby

Attach the wiring connector (provided) to the wire plug on the circuit board (refer to Figure 3).

Refer to Figure 4 to wire the detector’s relay contacts.

battery) before wiring the device.

DOOR

The arrows on the base indicate its correct mounting orientation relative to the door.

The mounting height range is from 7 ft to 15 ft. (2.1 m to 4.6 m) above the floor.

2. Remove the back cover from the detector. Insert the head of a small straight edge screwdriver into the locking tab and pry the back cover off.

When the back cover is removed, the front cover and detector module separate.

3. Route the wiring as necessary through the wiring entrance (refer to Figure 2). For surface wiring, use the break out wiring entrance on the front cover (at the same end as the wire entrance).

4. Loosely mount the back cover to the mounting surface using the supplied mounting screws.

5. Mount the detector module to the back cover. Aim the detector for the desired coverage.

Coil excess wiring behind the back cover along the channels provided.

3.2 EMF (Voltage) Spike-Protected Relay

Pins 6 through 8 (wire colors gray, green, and orange) comprise the EMF spike-protected relay. Refer to Figure 3.

Use this relay when connecting inductive loads to the detector. This relay protects the detector from inductive loads that might deliver damaging EMF spikes.

3.3 Non-EMF (Voltage) Spike-Protected Relay

Pins 3 through 5 (wire colors yellow, violet, and blue) comprise the nonEMF spike-protected relay. Refer to Figure 3.

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). Failure to use a bridge rectifier/diode may reduce the lifetime of the relay. Refer to Figure 5.

UL 1034 listed magnetic locks typically are already EMF spike-protected, and therefore do not require the bridge rectifier or diode as shown in Figure 5. Adding a bridge rectifier/diode to an EMF spike-protected device can cause unwanted delays in response. Refer to the magnetic lock’s documentation for more information.

4.0 Configuration

Use the on-board DIP switches to configure the operation of the detector. Refer to Figure 6 for proper switch positioning.

4.2 Relay Mode

DIP Switch 2 selects the relay mode. This allows you to select a fail safe by default, or a fail secure mode. Refer to Table 2 and Figure 6 for more information.

 Fail Safe: In the event of a power loss, the REX detector releases

the device connected to it (for example, magnetic door lock or electric door strike).

 Fail Secure: In the event of a power loss, the REX detector does not

release the device connected to it (for example, magnetic door lock or electric door strike).

In Fail Secure mode, the REX detector shall be installed in a manner that does not impair the intended operation of panic hardware used in conjunction with the REX detector.

Failure Secure mode must be authorized by the local Authority Having Jurisdiction (AHJ).

4.3 Led Enable/Disable

DIP Switch 3 selects whether the on-board LED is enabled or disabled. If enabled, the LED operates normally when motion is detected.

ON Enabled (Default)

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.

4.1 Resettable/Non-resettable Timer Selection

DIP Switch 1 determines if the relay resets at the end of latch time, or if latch time is extended by additional motion. Refer to Table 1 and Figure 6 for more information.

 Resettable: The relay activates when the detector first sees motion.

Any additional motion restarts the latch timer so the relay deactivates only when the detector no longer sees motion and the latch time has expired. Hint: This setting works best when bypassing a 24-hour contact.

 Non-resettable: The relay activates when the detector first sees

motion. It deactivates when the latch time ends, even if motion is still present. Hint: This setting works best when used with an access control system.

4.4 Latch Time

DIP Switches 4, 5, and 6 set the relay latch time. Latch time is adjustable from 0.5 sec to 64 sec. It indicates the amount of time the relay can remain active after the detector first sees motion.
