• 3 digital inputs (unsupervised, for predefined system monitoring) Additional security I/O points are achieved by adding expansion modules. A fully expanded SEC-H-600 can support a total of 32 readers (using 15 SEC-H-R2R expansion modules). Or, other combinations are possible with fewer readers but more general usage I/O using SEC-H-RIO expansion modules.
SEC-H-600 SECURITY CONTROLLER The Security Controller and its expansion modules all have end-mounted, 6-pin, connectors that support direct chaining of modules into assemblies. Connectors pass RS-485 communications and DC power (and battery backup) through connected modules. Also, you can mount expansion modules remotely from the Security Controller, and use the supplied 6-position terminal plugs to wire RS-485 and backup-battery cabling between the Security Controller assembly and expansion module assemblies.
Enclosures. These enclosures meet the UL 294 listing, have a pre-mounted DIN rail (or rails), and include a door with a key lock and tamper switch. Two models have an integral 30W 15Vdc power supply that powers the SEC-H-600 controller and/or the expansion modules inside the enclosure.
(one reader per door), plus additional I/O points. See “Onboard Security I/O” on page 2. 2. Per SEC-H-600 controller, a maximum of 15 additional SEC-H-R2R (2 reader) modules and SEC-H-RIO (remote I/O) mod- ules total, in any combination. If needed, all 15 can be SEC-H-R2R modules. See “Expansion Modules” on page 2.
(W) and minimum Amp hours (Ah), for all devices. Where n is number of modules: • Min. power supply (W) = SEC-H-600 W + (n x SEC-H-R2R W) + (n x SEC-H-RIO W) = total W • Min. backup battery (Ah) = SEC-H-600 Ah + (n x SEC-H-R2R Ah) + (n x SEC-H-RIO Ah) = total Ah NOTE: Backup battery(ies) are often sized greater than the recommended minimum, for additional reserve.
When using an Enclosure Power Supply and backup battery to power the Security Controller plus all expansion modules, and some modules are not mounted in the same enclosure with the SEC-H-600, you must be aware of voltage drops in the connecting “trunk power”...
If using multiple powered Security Enclosures (SEC-ENC-H-1, SEC-ENC-H-2) to power a large system, and running only battery backup power from the SEC-H-600 controller (on terminals PS-, BB of the SEC-H-201) to expansion modules in other enclosures, be aware that the output load cannot exceed 2.5A.
• Medium or large sized WEBs-AX Security Enclosure, model SEC-ENC-H-1 or SEC-ENC-H-2. See “WEBs-AX Security Enclosure,” page 4, for more details. • Suitable tools and supplies for mounting enclosure, SEC-H-600 model of Security Controller and expansion modules, and for making all wiring terminations.
NOTE: All U.S. Installations: For a UL Listed system (UL 294) you must mount the Security Controller (SEC-H-600) in a “WEBs-AX Security Enclosure,” page 4. All expansion modules must also be mounted in a WEBs-AX Security Enclo- sure, either the same enclosure or in additional enclosures.

SEC-H-600 SECURITY CONTROLLER WIRING DETAILS The following sections provide general wiring information: • General Wiring Rules • Connection Overview • Grounding • Cable Types and Lengths General Wiring Rules The authorized installation contractor should comply with the following rules: • Obey all national, state, and local electrical and safety codes.
5. Prepare power wiring (leave the unit powered off). See “Power Wiring,” page 25, for details. 6. Connect the backup battery to the SEC-H-600 battery connector, and apply power to the unit. See “Connect the Backup Batteries,” page 26, and “Apply Power,” page 27.
• “Digital Input,” page 22 Door Terminal Associations The SEC-H-600 controller provides access control for two doors. For each door, the controller allocates: • One Reader Input (for a Wiegand-type, 12V reader) • Two Supervised Inputs: one for door switch monitor, one for REX (request-to-exit) •...
SEC-H-600 SECURITY CONTROLLER Example Door 1 Wiring Figure 7 shows a Security Controller wiring schematic for a door with an HID-type reader, normally-closed door contact, normally- closed exit (REX) device, and a fail-safe DC door strike (normally-closed control). Fig. 7. Example Door 1 wiring (fail-safe).
Reader Input The SEC-H-600 controller has two door reader inputs, each supporting a Wiegand-type 12Vdc reader. Each reader input has a 7- position connector, on the circuit board labeled as Card Reader 2 and 1 (see Fig. 4 on page 12). Typical wiring is shown below in Fig.
Supervised Input The SEC-H-600 controller has six (6) supervised inputs, located on three 3-position connectors next to the DB-9 connector (see Figure 9 below). Under each connector, terminals are labeled SIn, GND, SIn, for example: SI3, GND, SI4. This means when wiring, two conductors are typically landed to each GND terminal.
SEC-H-600 SECURITY CONTROLLER Supervised Input Wiring Notes • The device monitored by a supervised input should have dry contacts (voltage free) as either a normally-open or normally- closed type switch. Mount the device per the vendor’s instructions. • Use shielded, twisted-pair, cabling to connect the device to the Security Controller. Maximum cable distance is 2000 feet (610m) •...
Relay Output The SEC-H-600 controller has four (4) Form-C relay outputs, each rated to switch 24VAC/DC loads up to 3A. Output terminals are located two 6-position connectors next to the card reader 2 input (see Fig. 4 on page 12). Terminals are labeled numerically 1 and 2 under one connector, and 3 and 4 under the other connector.
SEC-H-600 SECURITY CONTROLLER Auxiliary Relay Output Wiring Relay outputs 3 and 4 are available for controlling an auxiliary device, such as a horn annunciator. Figure 11 shows example wiring for controlling an output device. Fig. 11. Relay output wiring from Security Controller to an auxiliary device.
Digital Input The SEC-H-600 controller has three (3) digital inputs, located on a 4-position connector next to supervised input connector (see Fig. 4 on page 12). Under the connector, terminals are labeled GND, DI1, DI2, DI3. This means when wiring, as many as three conductors can be landed to the common GND terminal.
Connect communications wiring to the Security Controller using ports on the bottom of the unit (Fig. 4.), which include: • Ethernet • Serial NOTE: Prior to connecting cables, provide strain relief for them to prevent damage to the controller. Fig. 13. Security Controller (SEC-H-600) bottom side, cover removed. Primary Ethernet (RJ-45) USB port NiMH battery pack in...
Serial There are two serial ports on the SEC-H-600 base unit. At the bottom of the board (see Fig. 13.), the DB-9 is an RS-232 port using an DB-9 plug (male) connector. At the ends of the unit, an RS-485 port “passes through” the unit using the lower 3 terminals of the 6-position connectors.
Door strike power, as well as power for other loads switched by the SEC-H-600 and/or its expansion modules, should always be provided from a different source. Do not apply power to the SEC-H-600 until all other mounting and wiring is completed. See “Power Up and Initial Checkout,” page 26.
SEC-H-600 SECURITY CONTROLLER POWER UP AND INITIAL CHECKOUT Ensure power wiring to the Security Controller is ready—see “Power Wiring,” page 25. Refer to Fig. 4 on page 12 for the locations of the NiMH battery connector, status LEDs, and 4-position connector for 12V sealed lead acid backup battery(ies).
SEC-H-600 SECURITY CONTROLLER Connect the Backup Battery Connect the 12V sealed lead-acid Backup Battery to the 4-position connector next to the DB-9 connector, on terminals BT+ and BT-. When the Security Controller is powered up, charging voltage is applied to the battery(ies).
SEC-H-600 SECURITY CONTROLLER Providing that the backup battery has tested good, upon loss of primary power the system operates from this backup battery power until the charge level of the onboard NiMH battery pack reaches 0. Note that both batteries discharge in parallel. However, as the sealed lead-acid backup battery capacity is much greater, the NiMH battery pack discharges much slower than if these backup battery(ies) were bad or not present.
SEC-H-600 SECURITY CONTROLLER 4. Digital input DI1 of the SEC-H-600 must be wired to the door tamper switch of its enclosure. See Fig. 12 on page 22. If additional WEBs-AX Security Enclosures are used in the system, each door tamper switch must also be wired to DI1 of one of the contained expansion modules.
