Wireless Alarm Systems

Detectors, contacts and sirens talk to the control panel by radio instead of a cable, and the panel decides whether an event is an alarm. The systems here use two-way radio: Ajax Jeweller, which is encrypted, Hikvision AX PRO on 868 MHz with AES-128 encryption, and Pyronix Enforcer two-way wireless. The panel then reports to an app or a monitoring centre over its network or mobile connection.

Several products here state Grade 2. The Pyronix ENF/KIT1-UK Enforcer kit is titled Grade 2, the Pyronix MC1Z2/SHOCK-WE contact is described as a Grade 2 device for internal use, and the Ajax KIT2 S 90765.243.WH1 lists Grade 2 security features such as tamper and jamming detection. Check the grade stated for the panel and detectors where an insurer or monitoring contract asks for one.

Yes, if it is a hybrid panel. The Pyronix Enforcer V11 supports wired and wireless zones, reaching 66 zones in total when fully expanded with the ENF32UK/UPGRADE-WE, and the Texecom KIT-1005 pairs a Premier Elite 48 control panel with a 32XP-W wireless expander so wired and wireless zones share one panel. Ajax and Hikvision AX PRO kits are wireless systems built around their own radio.

The Pyronix KX10DP-WE is a pet-immune PIR with a 10m range, tolerant of animals up to 20kg, on two-way 868MHz radio. For Hikvision AX PRO, the DS-PDCL12-EG2-WE is a ceiling PIR covering 12m and 360°, and the DS-PDTT15AM-LM-WE is an outdoor tri-signal detector with dual PIR, microwave and anti-masking, rated IP65 for exposed walls.

Most of the kits here include a siren or sounder. Ajax KIT2 S and KIT5 S kits have a HomeSiren S indoors and a StreetSiren outdoors, the Hikvision DS-PWA64-Kit1-WE a DS-PS1-E-WE sounder, and the Pyronix ENF/KIT1-UK and ENF/KIT3-UK a wireless Deltabell module. The Texecom KIT-1005, the Ajax KIT18 S, the Hikvision DS-PWA96-KIT1-WE and the ENF32UK/UPGRADE-WE panel upgrade name no siren, so add a sounder to those.

Battery life is stated per device and varies with how often it transmits. The Hikvision DS-PDHT-E-WE heat detector lists a 10-year battery, the Videofied IDC200 door contact runs on one lithium battery lasting up to four years depending on activity, and the AX PRO DS-PWA96-KIT1-WE panel has an onboard battery backup rated at about 12 hours if the mains fails.

Yes, where the panel supports ARC reporting. The Hikvision DS-PWA96-KIT1-WE and DS-PWA96-Kit2-WE report in SIA DC09 or Contact ID, and the Pyronix ENF32UK/UPGRADE-WE supports DIGI-LAN, DIGI-GPRS and DIGI-PSTN modules with Contact ID IP and SIA formats. The Ajax KIT2 S 90765.243.WH1 is supplied ready for accredited installers, with Wings photo verification support.

Through Ethernet, Wi-Fi or a mobile SIM, depending on the panel. The Ajax KIT2 S 90765.243.WH1 hub has Ethernet, Wi-Fi and dual micro-SIM cellular with automatic failover, and Hikvision AX PRO kits report over LAN, Wi-Fi and cellular. The Pyronix ENF/KIT1-UK has a DIGI-Wi-Fi communicator, and the ENF32UK/UPGRADE-WE adds built-in Wi-Fi for the HomeControl2.0 app.

Yes, with a wireless contact link. The Hoyles WLR121KIT is a pair of 868MHz transceivers that take a clean contact input at one point and give a clean contact output at the other, up to 60m apart with no obstructions, with 1A relay outputs. The WLR121KIT units need a local 12VDC supply apiece, and paired units ignore other pairs nearby.

Some Dahua devices here do. The DHI-ARM7011-W2(868) is a wireless dry contact relay for switching a 0V to 36V DC supply at 5A, and the DHI-ARM7012-W2(868) WallSwitch switches 100-240 VAC and monitors voltage, current and energy use. The ARM7011 and ARM7012 use two-way frequency-hopping radio with encryption and interference or jamming detection.
