Alarm Detectors

The Bosch ISC-BDL2-W12G is the dual-technology detector for a room with no pets in it: passive infrared and 10.525 GHz microwave Doppler radar over 12 m x 12 m, wall to wall, with an improved lookdown zone under the detector.

What you get

• 1 × ISC-BDL2-W12G detector, white high-impact ABS

You’ll also need

• An alarm panel with a spare zone and a 24-hour tamper circuit
• A cable run from the panel carrying its supply, the alarm relay and the tamper, plus the end-of-line resistors the panel requires
• A bracket if it is not going flat on a wall or into a corner, such as the B338 ceiling mount

The Bosch RFPR-12 is the RADION wireless motion detector for a room the dog still uses: a 12 m x 12 m pattern, pet immunity to a 13 kg dog, and a lithium battery that runs for years, so a room gets covered without a cable.

What you get

• 1 × RFPR-12 RADION PIR detector in a white plastic housing, the version for Europe, Africa and Australia

You'll also need

• A RADION receiver on the alarm panel, such as the RFRC-STR2 sold here
• A CR123A lithium battery when the time comes to replace it
• A bracket if it is not going flat on a wall or into a corner, such as the B338 ceiling mount

The Honeywell 2012/24AUSI is a low-voltage photoelectric smoke alarm with its own sounder: it wakes the room on its own at 85dB(A), interconnects with up to 24 alarms in total, and reports to a security panel or access control system through a Form C relay.

What you get

• 1 × 2012/24AUSI photoelectric smoke alarm in a low-profile ceiling-white housing
• 1 × mounting ring and a 9 VDC back-up battery, both supplied with the alarm

You'll also need

• A 10 VDC to 30 VDC supply, typically from an alarm panel. The ICP-SOL3-P and CC610P are the panels sold here; check their supply and zone inputs against the figures below
• Four-wire cable from the panel for power and the relay, plus the end-of-line resistors the panel requires
• A ceiling position in the area to be protected, and cable between alarms if they are to interconnect

The Bosch ISC-PDL1-W18G is the Professional Series TriTech detector for a large commercial space: PIR and 10.525 GHz microwave working together over 18 m x 25 m, switchable down to 8 m x 10 m, with anti-mask supervision and SCEC approval for Australia.

What you get

• 1 × ISC-PDL1-W18G TriTech detector, white, in a high-impact ABS enclosure with a built-in bubble level

You'll also need

• An alarm panel with a spare zone and a 24-hour tamper circuit. The ICP-SOL3-P and CC610P are the panels sold here; check their zone inputs against the figures below
• Cable from the panel carrying 9 VDC to 15 VDC, the alarm relay, the trouble relay and the tamper, sized 0.2 mm² to 1 mm², plus the end-of-line resistors the panel requires
• A bracket if it is not going flat on a wall or into a corner, such as the B338 ceiling mount

The Bosch CDL2-15G is a hardwired Commercial Series Gen2 TriTech motion detector that pairs passive infrared with a 10.525 GHz microwave Doppler radar over a 15 m x 15 m pattern, and builds the end-of-line resistors, a bubble level and a lift-gate terminal strip into the housing so installation can be faster by up to 45%.

What you get

• CDL2-15G Commercial Series Gen2 TriTech detector (order number F.01U.383.078) — alarm relay, trouble relay and supervised tamper contacts, with DIP-selectable end-of-line resistors on board

You'll also need

• A hardwired alarm system with a 9 VDC to 15 VDC supply and supervised normally-closed inputs matching the detector's alarm, trouble and tamper contacts
• Cable of Ø 0.40 mm to 1.29 mm from the detector to the alarm equipment; its EOL values must match the 1.0 k, 2.2 k or 33 k resistors built into the detector before they can be used
• The optional B338 ceiling-mount bracket for a ceiling position; the B328 gimbal and B335-3 swivel brackets are the angled wall options

The Bosch ISC-PPR1-W16 is the Professional Series passive infrared detector for a large indoor commercial space: 18 m x 25 m of coverage, switchable to 8 m x 10 m, with tri-focus optics and sensor data fusion doing the work that keeps false alarms down.

What you get

• 1 × ISC-PPR1-W16 detector in a white high-impact ABS enclosure
• 1 × hardware pack with two flat-head screws, two screw anchors, a nylon cable tie and a pattern mask, plus a literature pack

You'll also need

• An alarm panel with a spare zone and a 24-hour tamper circuit, supplying 9 VDC to 15 VDC. The ICP-SOL3-P and CC610P are the panels sold here; check their zone inputs against the figures below
• Cable from the panel for the 9 VDC to 15 VDC supply, the alarm relay and the tamper, sized 0.2 mm2 to 1 mm2, plus the end-of-line resistors the panel requires
• A bracket if it is not going flat on a wall or into a corner, such as the B338 ceiling mount

The Bosch RFSM2-A is a RADION wireless smoke detector for homes that want fire detection on their Bosch alarm panel without running cable: photoelectric smoke sensing plus fixed and fast-rise heat sensing, its own 85 dBA sounder, and supervised reporting to the panel over 433.42 MHz radio.

What you get

• 1 × RFSM2-A detector with the radio module and two CR123A batteries installed
• 2 mounting screws and 2 wall anchors

You'll also need

• A B810 wireless SDI2 bus interface at the panel
• A compatible panel. Bosch lists the G Series B9512G and B8512G, the B Series B6512, B5512, B4512 and B3512, and the GV4 Series D9412GV4 and D7412GV4 at v2.00 or higher; on a Solution 6000 support was added in firmware V2.53.19
• An indoor, dry ceiling or wall position on a flat rigid surface

The Dahua DH-ARD2251E-W2 is an outdoor wireless detector for the Dahua AirShield alarm system that combines three detection technologies — PIR, microwave and an optical verification camera — to catch a real intruder outside while shrugging off the things that fool ordinary outdoor sensors. It detects movement up to 15 metres, has pet immunity to around 40 kg, supports anti-masking, and captures a short verification image so you can confirm an outdoor alarm before you act. It is IP66 rated and links to the hub over an encrypted 868 MHz two-way connection. It works with the ARC3800H AirShield Hub 2 only, which is sold separately.

Key points
- Triple-tech detection: PIR + microwave + optical, with intelligent filtering
- Outdoor range up to 15 m at 90° (1 m mounting height); 3 sensitivity levels
- Pet immunity to about 40 kg / under 80 cm; anti-masking and tamper
- Built-in camera for alarm video verification (IR up to 15 m, 110° view)
- 868 MHz two-way radio with AES128 encryption and frequency hopping; up to 1,600 m
- IP66, -25 to +60 C, 4x CR123A; works with the ARC3800H AirShield Hub 2 only
